truck has been down too long

so the story goes....
driving my truck down the hwy and it started to sputter. Like it wasnt getting fuel. After getting it towed home i opened up the fuel bowl and there wasnt any fuel.
So i replaced the fuel pump. While i had the fuel bowl i rebuilt the FPR and the fuel bowl.
So i went to start it and i was not getting fuel to the bowl at all.
I put a fuel gauge to it and i wasnt getting any preasure at all.
i tried switching tanks and still no fuel flow.
My question is. If there a issue with one of the tanks wouldnt just switching over to the other tank eliminate the issue?
Any other thoughts would help.
thanks

tank selector valve failed and stuck in the center is a possibility.

remove suction line @ quick disconnect on frame driver side behind front tire, remove fuel caps, blow compressed air in to line (gently like 5 pounds) and have someone listen for bubbles or air flow into tanks, switch tanks and verify both.

also check fuse for tank selector.

You could have a pinhole of rust in a fuel line / sender somewhere too (my tank senders are stainless but the rail lines looked mild steel). The fuel pump sucks from the tank, so if there is air getting in anywhere itís going to pull air before fuel. Could be a rubber flex line to quick connect oring too. It can leak air under vacuum but not fuel.

If you really wanted you can cut the rubber or steel line feeding the bowl under the truck frame rail and run a piece of 3/8Ē fuel line from it to a can of diesel and thatíll rule the tanks, senders, and fuel valve out. You can always couple it back together with rubber. Thatís what efuel kits do anyway.

Air on the rear sounds like there isnít a shower head in the pick up or itís not below the fuel
level. Blowing air wonít find a pinhole leak though.

You dont need a return line to make it run. It'll suck the fuel can out faster and just put it back in the tank but if you have a fuel return line leaking itll be an external leak and you'll see it, and it will not affect your trucks ability to run.

I do not think filling the fuel bowl up will get your truck started and running, it'll help, but its going to take a minute or two of running just to get the air worked out of those heads and injectors.

I sure am glad I went e fuel. soap up the line and blow are in them again. see of you get bubbles. I can see a minor leak keeping it from getting enough fuel to get it running. I would fill up the fuel filter area and try starting it. Maybe the RPS will get things going.

ok


so I hooked up the supply line to a 5 gallon jug of diesel.
I also filled the fuel bowl. tried to start it and got nothing. Fuel pressure gauge off the FPR wasn't moving.
So when is fuel pressure measured? at what point.
When I re-oringed the FPR did I mess it up? im out of ideas...

I'm sure it's possible it got messed up. Maybe your fuel pump is broken? And the fuel bowl leaked out through the broken pump into the crank case? I'm not sure if that can happen but thats all thats left if you haven't replaced that pump. Unless there is a crack somewhere the supply line or rubber line leading to the fuel pump causing it to draw air.
