Fuel System problem on 1986 Bronco
I just bought a Bronco, a 1986 with the 351w. This is old enough to still be a carb, a Holley 4180. The basic mechanicals are solid, but there is some tune up work that needs to be done. The truck sat for over a year without being started (joy!).
The truck just doesn't want to stay running. The timing is good and I sorted out any vacuum leaks (now a ROCK solid 21hg at idle). Based on the problems I am seeing, I am pretty danged confident that the problem is fuel delivery. Sure, check the fuel filter, volume from the pump, maybe the carb is all gummed up. Basic stuff, so I am going to check the easiest to get to stuff first.
I can't find the fuel filter! The is an on-block mechanical fuel pump. Unless I am crazy, and remember my pre-EFI world wrong, the fuel filter should be between the pump and the carb, right? I spent my post-work and pre-sun down hours tonight trying to find the stupid thing. It doesn't LOOK like anyone has messed with the truck, it's all pretty stock. It is possible a previous owner did remove the filter and just run hose from the pump to the carb.
Can anyone confirm the fuel filter location on a 80-86 Bronco (carb, not efi)?
