Dropped fuel tank

[Ryan Rønning]

So I droped the tank on my truck at the suggestion of some of the folks on here. My pick-up is not clogged or anything. I got to thinking that if that is not it then what could it be. I poured diesel in to a pale and turned the key to on and let the pump suck fuel up. The in tank pick up is seems to be sucking air even when sunk in fuel ther-by not allowing me to build any fuel pressure. any ideas?

Really, You guys have no advice?

Did you clean the screens that are inside of the pick-up? I didn't know they were in there until after I put mine back on.

I've changed 3 sending units in 3 seperate 7.3s because of cracks in the pipes that suck air when the fuel level drops below the crack. Pressure will slowly drop as you accelerate until there is no pressure and the engine stalls.

Just a note.....do not support the tank in the middle where the sending unit is located. You can damage it.

Is the problem you are having is no fuel to filter, thats the issue I have on another post by me. I am afraid that is my issue trying to get as much info as possible. Looking into the itp fix for this with the external pre pump filter.

Isn't that why guys do the in-tank mod to eliminate the mixer valve?

Update:

I got the tank all dropped and cleaned out. Took apart the pickup and cleaned the screans, did the "hutch mod", put a clanp on the pick up as mine was missing and it is supposed to have one, did the harppon mod and then put it all back in the truck in a lil less then 2 and a half hours. I reckomend everyone do this as it is very easy and dropping the tank is simple (if its empty) I did the whole thing myself.

Trucks runs better now.

Good for you. Did you find much crap in your tank? Mine was very clean.
