Engine/Transmission (1998.5 - 2002) Will it pull 35 gallons out of the fuel tank?

I was wondering how low the truck will pull fuel out of the tank? Will it get the whole 35 gallons or do they run dry at 33 or 34? I bought my truck a month ago and keep going a little further each fill to see where I'm really at. With the needle just starting to touch the the red line, I still have 7 gallons left!

i have run mine for 75 miles on the red line and still only put 28 or 29 gallons in it at fill up

I would think that it will pull most of the fuel out of the tank, but your gauge is going to read empty well before that happens. You don't want to flirt with that to much, starving the VP44 for fuel is not something to do.

You can look at these photos of the fuel module and pickup point where fuel enters the system.



It would appear to me, from my experience inside the module, that the truck can run with approximately 3/4" of fuel in the bottom. However there is no sump... and sloshing will affect how well it runs. I can tell you that the module helps with the sloshing as the screen fiber mesh is more than just a filter and the module is a reservoir of sorts to hold fuel during low level sloshing.



As to whether it will pull 35 gallons out depends on how much fuel the tank actually holds. Theoretically you could almost drain it under ideal conditions. Real world wont let you.



I wouldn't try it on the road for sure. The gauge probably fudges a little from looking at my float. Its a factor of safety for you and you should respect that. The heat from running the injection pump gets transfered back to whatever fuel is recirculated into the tank. Low levels of fuel get real warm real fast... and that may not be good for the VP44 injection pumps cooling needs.
