1997 Chevy S-10 4 cyl Two Wheel Drive Manual

Where is the fuel pressure Schrader valve on this model pickup?
Thankyou in advance -
Rob
PostScript -----------
This is a multiport system, and we can't find the valve anywhere on the fuel rail. This may not be the original engine; did GM put the valve somewhere else in other years?
Thanks -
Rob

Is it a TBI or MPFI fuel system?

TBI-disconnect the fuel line between the TB and fuel filter hook up the gauge-

MPFI-the schrader valve is on the fuel rail

It is an MP system, and we're not positive this is the original 1997 engine. But we cannot find the valve anywhere on the rail; did GM put the valves anywhere else in other years?

It has to have one if it has a fuel rail if not backtrack to the fuel fuel filter and try to take it there.
