How to replace a fuel supply line without any leaks at the snap connector at the fuel pressure regulator supply line. I dropped the gas tank to replace the left side rear brake line which I completed successfully. However the pressure regulator nipple seal developed a small leak at the neck and I chose to replace it along with the snap connector (about 7 ins. long) and connects to a crimped 3/8 10 ft.length of stainless tubing that connects to the EFI at the manifold.I chose to replace this rigged nylon line due to kinks in the original line and new O-rings for a positive seal.
Before I re installed the tank I started truck and let it run 30 minutes "dropped for visual purposes" without a drip;disconnected the elect. fitting and fuel supply then applied a little more heat to the new rigid for a tighter fit at the snap fitting.Once the truck was back together I started it,but now it is leaking at the connector pretty good so I immediately shut it down.The only thing I can think of is that the new rigid 3/8 tubing does not require a great deal of heat and does not react like other heat shrink material. I would appreciate your thoughts if you have ever performed this type of repair regarding rigid fuel tubing/fittings...
