Hi, I have a 97 GMC Sierra with the 5.7 liter engine.
Has anyone ever tried installing an after-market in line fuel pump on a vehicle similar to mine?
I was considering it as a means to cut cost, but I have no idea if it would work.
My thinking was to either disconnect the in tank pump all together, or leave it hooked up as a supply pump.
Would the in line pump be able to draw through the in tank pump?
If I leave the in tank pump hooked up, could it somehow over pressure the line or the in line pump, if so are there any after market regulators available to regulate the in tank pump between the tank and in line pump?
I know it sounds like I'm opening a can of worms, but I can't help but wonder if there is a more economical solution to this, than pulling off the bed, paying $500.00 for a pump, and risking damaging the lines etc., in the process.
Like so many post I have read, I am having very weird problems with the fuel pump.
It bleeds down overnight when its cold outside.
Then even after purging the line, it won't pump enough pressure till the pump warms up. Lately I've had to jumper the pump so it will run long enough to warm up before even trying to start the engine.
Any suggestions would be appreciated.
If you think I'm nuts, feel free to say so!
Thanks, Nick
