I thought people were sdaying all 2004.5 fuel pumps were on the filter housing. Well today for the first time I took the time to start my truck with the door open. I then turned key forward and heard a buzzing coming from the fuel tank area (electric pump on tank i guess). would this be what the buzzing was? or do i have 1 on the filter housing because i didnt hear anything there? also what is better the tank mount or the filter mounted factory pump?

 

The tank pump is better because it is easier to push than suck. the Canister pump is easier to upgrade because you do not have to drop the tank.

 

04.5 are filter mounted unless someone took it to the dealer and had the intank lift pump installed

 

Just look at the filter housing. It will be a black fuel pump-looking thing.

All you have to do is look on the back side of the filter housing and see if there is a black cylinder. There should be on an 04.5.

 

how big roughly? I dont recall seeing anything there. when i turn key forward wouldnt it make noise there? It makes noise somewhere by the fuel tank. Also I had boughten the truck used so. someone have a pic of their filter housing with or without pump?

 

The previous owner had the stock filter mounted pump removed and replaced with an in-tank lift pump.

 

i wonder if its stock or some bigger unit? i should get off my butt and check. maybe its mounted in the frame even who knows?

 

If it's mounted on the frame or installed in-line some where it's after market.

There is no after market in-tank lift pump so if you don't see any lift pump any where it's a factory retrofit in-tank lift pump.

 

ok ill go look. i tried it again this morning and sure enough the pump is pumping from rear somewhere. its probably in tank.
