What carburetor came stock with my Kingston motor home

Hi,

I attached the detail about the 460 carburetor for your model year. Let me know if you need more information. Thanks

I thank you very much. I've been searching for details about this motor home after but it from a lady that didn't know much. The problem is that it won't go over about 25 mph. I have replaced most of the vacuum lines and the shift modulator. The carburetor that's on it is an Edlebrock 1406 0644, and I don't know a lot about carburetors, but to me it seems some parts are missing? I just looked on line for that Holley carburetor you told me earlier, lmao. Can you tell where I might be able to find a good deal on a rebuilt Holley 4180-c 4bbl ? Or something that will work and is easy to adjust. And won't break the bank. Thanks

The Holley 4180 was originally meant for 351 CID but worked very well that they fit it to the 460. With this being the case, just make sure you are getting one with the C.

However, the Edlebrock that is on there is a 600 CFM carburetor that is like a cousin to the Holley.

If parts are missing then it may need to be replaced but if a rebuild will correct the issues, that can be done FAR cheaper and is pretty easy.

If you are going to purchase one, I would give one of the sites like Jegs or Summit or the Holley Store, a call and tell them what you have and they should be able to send you everything you need to make it work. Back then, it didn't really matter if it was a motor home our just a pickup truck, the engine was all the same.

Thank you very much, and I'm hoping that will fix it. I'm not sure what else to check. If you have any ideas please feel free to let me know... Thanks again.

Good morning,

Just to add for you, rock auto has the original 4180 in stock for your motor. I attached it on this post for you.

Hi guys, it's hippie again... So I replaced the carburetor with a Holley 600cfm,.. I got it running at idle real good, when I get drove it the fuel pump went out. (No fuel to carburetor)... I know there's no manual pump on the engine (already looked)... I found what I believe to be an external electric fuel pump. I also have an on board gen. My question has a few parts to it. First, if that external pump works for the engine, does that eliminate any internal pump?. The second part is, How does the gen get its fuel? And for a recap:This is on a 1984 e350 24' Kingston motor home, 460 engine with a C4 transmission. With two fuel tanks. Thanks for any information. hippie

Hey Hippie Mike.

We need to keep the questions to one topic per post or when people search for them they won't find different issues under different headings.

Sorry to make you re-post this but if you don't mind starting a new question for this one we would appreciate it.

https://www.2carpros.com/questions/new

Here are a couple of diagrams that I found for the fuel system. Looks like it says you have an in tank electric pump. I don't show an external pump or a mechanical pump. So I assume this has been altered due to it being a motor home. However, I will look for the new post and we can dig further into it.

Okay, that's fair. staying in the external fuel pump. If it has been modified with an external pump, does the fuel typically go through the internal pump as well? Thanks for any information.Hippie

And here's another question concerning having duel tanks. If the pump in the rear tank goes out, could I just run off the front tank?

I would expect the in tank pump would still have to work. However if they just put a pick up tube in the tank then clearly it would not because it wouldn’t be there any more. I don’t think the in tank pump can be used as just a pick up meaning it’s just like a tube in the tank that draws the fuel out. I think the pump would have to work so the only real way to know is to see what’s in there. Anytime something appears to have been modified it’s best to just investigate it and see what is there.

Yes. You can run off of just one tank. I had an F150 with duel tanks and the rear pump went out so I just ran off the front for a while. Only issue is you have a smaller tank. But this is why Ford went to this is so that you have a back up for when a pump went out. You should have a tank switch that allows you to select which tank to run off of.

Awesome! Thank you very much. That is what I was hoping to hear. And that makes sense. Thanks again

So here's a question about on board generators: How or what provides fuel to the generator? Does it have its own fuel pump?

I bet this is what your external fuel pump feeds. If the generator doesn't have its own fuel tank then it pulls the fuel from your main tank. Clearly it will need a pump to draw it out. I would just follow the supply line from that pump and see if goes to your generator.

Hey guys, well ends up that that external fuel pump runs the engine. I'm guessing that it was a aftermarket install so they (previous owners) didn't have to drop the tank to replace the original pump inside the tank. In the mean time, the external pump is feeding the engine, my question to y'all is this,.... That pump is wired to an on key fuse, however, the pump never shuts off, will that hurt the jets in the carb ? Or is it a possible problem in the future ?... Thanks for any info.....

Okay, if it never shuts off, it will drain the battery.

It is connected to the wrong fuse. It is connected to a battery-powered fuse instead of a fuse that has voltage with the key on only.

You need to change that wiring.

Roy

Sorry ron,.. Maybe I didn't wire it right,... But it is wired to a key on fuse.... I.e. When I turn the key on the pump comes.on and when I turn the key off it turns off,.... It don't stop pumping when the key is on.... I understand that that's what's supposed to happen,... I've understood that if you turn the key on (but don't start the engine ) that once the fuel lines build pressure and fill the lines to the carb, that it would stop pumping fuel and be on a stand by mode,... Until needed ?

Okay, since it is an aftermarket external pump and hard wired to the fuse box, that will not happen.

The ECM is what controls the 2 second prime. With the set up you have, the ECM has no connection to the operation of the pump.

Roy

Again sorry ron,.. This damn auto correct... It's supposed to say ... Maybe I didn't word it right....

Thanks Roy for that info,.. But what will not happen, ?... The pump won't turn off ? Or if won't hurt the jets in the carb?.. And I'm confused about the "ecm" ? What is that ? And what does it do ?

It will not harm the carburetor at all.

The ECM is the engine control module which controls all engine controls.

Roy

Thanks for that info,... I'm still having the same problem as when I started,.. Which is,... It won't drive over about 30/35 mph... It spudders... Here's what I've already replaced,... New(rebuilt) Holley carb,.. Most of the vacuum lines and the transmission shift module, I also put a new electric external fuel pump ( which was there already and am guessing the prev. owned installed )... I guess my question is... Got any ideas why ?

Okay, let us back up.

Did you check the ignition timing? If you did, what did you set it at and did you adjust it with the vacuum advance disconnected?

Did you check the compression on at least 1 cylinder?

The other thing would be the exhaust. Did you either drop the head pipe and road test or remove the O2 sensor to see if the performance improves?

Does the transmission shift through all the gears?

Roy

I'm going to put it on a trimming light tomorrow, and I'm guessing advanced if anything right ? Maybe 3-5 degrees... What's your suggestion? And no I hadn't checked the compression yet... Nor have i done the 02 sensor. And yes, it shifts thru 3 gears.... It has a c4 transmission. I just recently bought this motor home and don't know much about it. I can't find a owner repair manual on this type of motor home and chassis. Its a 1984 e350 Kingston motor home with a 460 engine. If you have any ideas on that too would be most helpful.... Thanks again... Hippie

Okay, I hope it is not a C4. It should be a C6. The C4 is way too small for this unit.

Do those checks and get back to me.

Roy

I checked the manufacturer plate on the drivers door and the code was "g" and a book I have on ford pick ups 1965-86 says it's a C4. If I'm wrong, please tell me the correct transmission. Like I said, I can't find a repair manual for this model...I will get to those tests and get back with ya.

Can you give me the complete vin number?

Roy

I am looking at options and the only one I see is the C6.

Can you post a picture of the transmission pan?

Roy

I'll try tomorrow. I'm pretty sure it's the original engine and tranny. If you could tell me what tranny goes with code G on a e350 ford that would be awsome... And if it's a C6 like you say.. That's interesting...

The only transmission listed for the 7.5 is the C6. It takes a special bell housing and the C4 does not have that option to bolt to a big block.

Roy

Hey guys, so it turns out the timing is fine, however, I did discover a exhaust leak on the egr plate that in between the carb and the intake manifold.... My question to y'all is this,.. Since the egr is plugged off, could I remove that plate and just install the carb to the intake manifold ?... By removing it will it effects the air/fuel mixture ?.... Thanks for any info.. Hippie

No, due to the blt pattern. It will not bolt up.

It needs to be there.

Roy

Roy, the bolt pattern is the same. They both slip into four threaded studs that are anchored in the intake manifold. I'm not sure I understand your answer... But thanks anyway

Take a look at the passages in the intake manifold where the plate bolts up. It has an exhaust port and an intake air port. With the plate installed, you do not see those ports exposed. That is the difference. You cannot just use a gasket and install the carburetor.

Roy

Hey,.. Question for you. Oh a 1984 e350 /460 engine, automatic Kingston motor home, I'm wondering about it having too small of an alternator will effect the performance of the engine? Now with a brand new 60 amp alternator, after starting it, I disconnected the battery and it dies. Is that because the alternator is too small? Thanks for any information. hippie

Due to the exhaust port. It will overheat the base of the carburetor. You need that plate to be installed.

Roy

What about the alternator question? Can/will you answer that one please?

Okay, disconnecting the battery with the engine running is not a test and can damage components. It tests nothing.

The alternator needs battery voltage to work. When you disconnect the battery with it running, it should shut off.

If that was the original amp rating for the alternator, then that is good enough to maintain the battery.
