where is the pump located....

 

Just a thought but, with the pump in the tank and the tank level run down low before refueling, the pump and motor could overheat and burn up sooner?

Would refueling at 1/8 to 1/4 of a tank more often, while there is still fuel covering the pump and motor removing heat, help keep it cooler and therefore make it last longer?

Not sure just thinking out loud.

 

No.Fuel flo is fuel flo.Low or high.

 

I had poor fuel pump pressure on my truck.I talked to the dealer & a diesel shop last week,They told me that the 2005 in fuel tank pump retro fit is not much better.If you are running any kind of HP box the fuel pump is starved for fuel.My truck stumbled and check engine light came on, codes I had were 0192 & 0237.I had a FASS system installed this week and keep a constant 12-13 psi of pressure (WOT) on my fuel pressure gauge.coobie

 

If your referring to the old style lift pump its located on the back side of the filter canister.

 

I have a 05 cummins and it lossed all power but it would still run. check engine light came on and it was a PO251, I believe. It said it was the injection pump metering control A. Is the injection pump and the lift pump the same thing If not what is the differents? Sorry if this is a dumb ?? just I am new to diesel.

 

No, the lift pump get fuel to the injector pump and the injector pump get fuel to the commonrail/injectors.

It is under warrenty isn't it?

 

Yes, it is still under warrenty. The dealer just called and said that they had it fixed It's been a week.

 

Good.

 

another thought,,being as the duramaxs run a cp pump also,its my understanding that they dont even use any supply pump at all........anybody have input on this??...........bama

 

Last one I had die, I could re-start it but it would die if I throttled it hard. Limp mode style drove it 10 miles to house.
