My TBI fuel system requires 15PSI, and I see when searching through new fuel pump offerings they list anywhere from 26 GPH flow to as high as 75 GPH
There seems to be a lot of arguement whether the fuel pump actually being submerged keeps it any cooler than when exposed, because of the fuel flowing through it, saying submersion is an old wives tale.
I am wondering just how much fuel actually flows through it to maintain that 15PSI.
I most often drive with less than 1/4 tank and I doubt the top of the vertically mounted cylindrical fuel pump is submerged at this level.
I've had a few stalls recently, that I am not sure are fuel related, and it has restarted, but required the extra few seconds to restart, like it is building pressure after the fuel pump lost power or quit temporarily or sucked in some air.
I have checked the fuel wiring and connectors. The ground bolt was stripped but not loose or showing any signs of oxidation on the ring terminal or surface it was mounted to, and it has not stalled since, but I have not driven much since.
The Delphi replacement pump I am considering, says expected fuel pump life is 7 to 10 years seemingly irregardless of mileage.
The current Carter pump I am using, and suspect might be near or at end of life, was installed in 2006, mileage less than 40K.
Rockauto has fuel pumps ranging from 22$ to Denso at 64$, and I was considering the Delphi Bosch or Denso turbine style pumps as opposed to the gear style pumps.
I am not sure whether the Carter I have now is gear or turbine. It is not currently loud, but the one I replaced in 2006 was buzzing loudly before it failed.
So how much cooling does the fuel passing through the pump actually do, and how does that compared to the pump being submerged in fuel?
Would members here choose Delphi over Denso or Bosch?

I am considering replacing it proactively, just because of the age and the stalls, and the inconvenience and possible danger of it giving up entirely on the road somewhere.
