So I was running my 80hp Ford Lehman
for about 45 mins on idle and suddenly it shut off. My immediate suspicion was that it ran out of fuel. I checked below the racon fuel filter
and saw clean fuel with no signs of air.
Then I looked at the polishing filter and found that it was empty. So my thoughts were that my fuel filter might have been bad. It didn't "look" bad, but I don't know what a bad one looks like, and I replaced it anyways and tightened the cap up.
Next I tried to bleed the system. I turned the electric
on and went to see if the polishing filter was filling up...it wasn't. Then I opened up the two bleed screws on the injector block. There was some fuel exiting out of the farthest bleed screw, but nothing out of the nearest screw. I then used the lift
pump priming lever (which was seized in place, until I worked it free), and started seeing some bubbly fuel going into the polishing filter. I kept trying to prime with the lift pump but didn't get any fuel into the polishing filter.
Why can I not get fuel into the polishing filter with the lift pump?
Shouldn't the electric
priming pump be able to do this without me using the lift pump?
