Default Clogged pick up?

On my third Bosch 044 pump on my beans E fuel kit, first and second one totally died, third one seems to lose pressure when you get in it, fuel pressure is at 55-56 cruising, Stepping in it I can drop the pressure to Zero, then it builds back up, even harder when towing.

Thoughts? Pump is only 3 months old, first two did the same thing then totally died.

Ratchet strap a fuel can onto frame and stick fuel line into and draw from it while driving. If it's fine then yea tank issue

Take the fuel line lose and blow air through the line to see if clogged your foot pick up could be broke and a peices of it in line . . If u still have the selector valve it could be it . It could also be bad wiring. U want your fuel pressure set at 65 psi .

It probably sounds silly, but could it be your filter(s) is/are clogged?

Fuel pressure has been set at that since I got it 4 years ago, I will blow air through and see if it helps, seems like the front tank doesn’t do it as quickly as the back tank.

Might be screen plugged on bottom of intake in tank, although there is a by pass there too. Not sure how bean system works but if injector o-rings are going that o-ring debris will probably make it back into the tank via return line and pulled up against the screen possibly. Not that big o deal to drop tanks and check.

Blew air into both tanks and hauled close to 10K pounds with it today, fuel pressure seemed to stay good until I really got on it, about 30-40 mph stepping on it I got it to go to zero, but instantly shot back up, seemed to do better then before

The other thing I’d check is the vents for each tank. On my mid ship steel tank, it looked like it was caved in, however the tank guard was un damaged. I think what really happened was the vent got plugged and the stock pump created significant vacuum and deformed the tank significantly. Thats why I replaced with SD poly CCSB mid ship 132 litre tank, this spring.

Holy crap. Below 15psi can score the injectors. Id stop running it untill you found the problem. Get a different pump and drop the tanks and make sure they are clean. Do the hutch mod while in there on both tanks as well.. fuel pressure should hold rock solid at whatever you have it set at no matter if at idle or wot...

Could also be sucking air somewhere too...
