Anyone know the correct fuel line routing for a 77 Chev C-10?
I mean, does the fuel line, before it goes into the pump for the 350
V8, mount on the outboard side of the frame rail, or the inboard.
After I've driven a while and the engine is warmed up the vehicle
tends to stall out at stop lights or when slowing down. I had the
engine replaced a while back and I notice that the rubber fuel inlet
hose is on the inboard side of rail.
Could passenger side exhaust manifolds be vaporizing fuel thus causing
vapor lock and thus the stall?
Runs fine at ordinary speeds.
Vapor lock could easily be the problem if the fuel line is too close to the
manifold. Easy enough to check. Temporarily insulate the line with something
and see if the problem goes away.
I don't remember where the line was mounted, but since the tank was mounted
outside the frame, it wouldn't surprise me to see the line mounted the same
The fuel line comes out of the top of the tank,over the frame rail,and
inside the rail all the way to the fuel pump.From there it loops around the
front of the engine, and up to the carb..Try changing the filter in the
inlet of the carb.,and check the pressure.(should be 3 to 5 psi).If you have
dual tanks,the switching valve will be just ahead of the pass.side
tank.Carefully look at the rubber hose connections there,as that tends to a
source of suction leaks.Good luck.~Ed
