fuel delivery/ vapor lock?
Okay folks.... here goes.
1979 jeep cherokee s, 360 400 th, carter afb 4 bbl, edelbrock performer intake, bfgoodrich 33" MTA's, 4 inch suspension lift, 2 inch body lift, (all that is new or fresh rebuilt)
had sputter/ stall like the out of gas symtoms at 45.
replaced fuel pump
pulled fuel filter anad hacksawed it in half, it was packed with rust! pulled gas tank & it too was rusted out bad.
replaced with Poly tank from JC whitney source fit was great! replaced all rubber fuel lines,filters and rebuilt a brand new carter 4bbl.
problem still exists with a pratically brand new truck!
I am now kicking around the vapor lock theory and printed out some really early messages about this that was discussed like a thousand messages ago!
but now idicators point to fuel return system. also filling this thing with gas is a pain in the rear seal, nozzles keep shutting off, and I have to hold it pointing to the back of truck going real slow to keep it filling!
