Three weeks ago I needed to pick up two tons of hay (sorry I forgot to take pics) about 30 miles away from home. It was one of those 90* plus days. On the the drive back I was four miles from home when the engine stuttered and stalled. Pulled over and lifted the hood, looked around for a minute, saw the gas boiling the glass
fuel filter. Let it cool down, then carefully drove the rest of the way home.
This took a few revisions to the new engine to work out, it's only got about 1200 mile on it with a QuickFuel Slayer 600. Well the electric fuel pump had been on the the car when I bought 16 years ago with a 4350 4v carb. Never made friends with that carb. So I replaced that fuel pump with a new Facet 7-10psi electric and a Holly deadhead regulator. I plumbed in a pressure gauge just before the stock type filter (with the return line). That line also had the glass
filter in it. Only was getting 3-4psi. QuickFuel recomends 6-7psi
After more trial and error/learning I found that the glass filters (I have just always liked being able to see if gas was flowing) reduce fuel pressure by 1-2psi because of restricted opening at both ends. The filter inside did not make a difference in pressure. Next I found that stock filter was reducing pressure by allowing the excess fuel to return to the tank, which is what it is designed to do. If I capped off the return nipple and the pressure increased about 3psi. But I know it needs a return line.
So I replaced the deadhead reg. with a Areomotive reg. with built in return line and the filter, capped off, in front of it. Nothing like reinventing the wheel but it seems to be working, although I have not been on any "hot" drives yet.
This was the fuel line before:
After the changes:
Made a heat shied from galvanize flashing:
The QuickFuel required a throttle mod. because it did not allow WOT cable:
Finally the power steering pump had been needing to be replaced, stuck a filter in the return line there:
We'll see how it goes.
