Fuel pump ready to die????

[TurboTy]

whats up guys, the past couple days, i've noticed when i turn the key on and wait for start the fuel pump sounds like its suckin air bad, like its breathing through a straw, do these commonly go? i gotta check and make sure the lines are clear goin to it, but i'm pretty sure they are, my mpg if anything has gone up in the past couple weeks, the truck hasnt ran different at all really, but dont wanna end up on side of road with a beat fuel pump if i can change it now, lol..what do you guys think??

What is the quanity of fuel in the tank? Is it at around 1/4 or less?

Does having more fuel in the tank help at all?

it is a little less than 1/4 tank, i'm gonna fill it up tomorrow and see if it changes, i swear i've noticed it no matter what through this tank of fuel, but hard to say...i will def let u know asap

Don't fill the tank, just add another 1/4 tank or so.

If the situation improves with more fuel in the tank, you're probably sucking air through a leak in the fuel pickup inside the tank. Raising the level of fuel to a point above the leak will in effect stop it from sucking air. If that's the case, then you're a candidate for a "Hutch" mod.

Don't rule out that in your "mixing chamber" on the fuel pick up there are two screens inside of it. If these screens are plugged it may make you pump struggle alot to pull the fuel out of the tanks.

ok, i put bout a 1/2 tank in her today and the sound isnt as bad anymore, you can here the pump, but it dont sound like its suckin through a straw, lol...i'm goin to be painting my truck soon and replacing my beat up bed with a better used one so i will have that off, think i'm gonna do the hutch mod and make sure everything is cool while the beds off and i got easy access, thanks for the help guys!

don't discount the click lock fittings on the fuel lines either.
you can upgrade them with a piece of diesel fuel hose and eliminate 2-3 of them around the pump. they are known to leak.

You might want to "harpoon" the tank too as long as your in there.

"harpoon"? which mod is that?

"harpoon"? which mod is that?

Cutting off the extension of the tank vent that extends into the tank. It allows faster fill-ups where you can top off the tank all at once versus clicking the pump nozzle 1/10 of a gallon at a whack to get that last 2-3 gallons in.
