Moving fuel pump
I need some advice, Here is what I have going on. I have installed a carter 4070 pump just outside of my fuel tank, I have that pushing into a NAPA spin on filter and then it goes to the stock fuel pump. My question is can I move the stock fuel pump back by the tank, get rid of the carter and still maintain enough volume pushing through the spin on filter? The truck still has the OEM filter on the engine.
As for mods I only have the DP 80 econo tune with opened up exhaust and the 6637 filter.
Another option would be to allow the stock pump to suck through the spin on filter, but I believe these pumps are more efficient pushing than pulling. Correct?
Also is there a better pump than a stock replacement? this one has 175K on it and I'm starting to wonder how much longer its going to be around.
Thanks for the inputs.

Yeah, you can move the pump. I moved the stocker when I did my regulated return with fowl bowl delete. You just need to extend the wiring and drill new holes in the frame for mounting using the existing hardware.You'll have to run new fuel line from the pump's new location to the hardline up by the motor.

Ron's right, they do better pushing than pulling.

Thanks Ron, Guess I'll be moving the pump back by the tank this week end.
Can anyone tell me why you would wrap the filter during the winter? It seems to me the fuel would get just as cold and jell in the lines to the engine as it would in the filter?

Reduce the exposed amount of fuel to extremely cold air being feed through the filter, the only place gelled fuel will give you problems.
I hate plugged filters, cold fuel dripping down your arm to your arm pit, snow down your back laying on the side of the road, psd not wanting to run.

the filter still gets as cold as the out side temps..wrapping it keeps the bellow 0 windchills from deep freezing the filter...the lines are prtected by the fame where there tucked way up in..and any water that is collected should be in the filter..not the lines..

Well Ron maybe you will get some pictures posted by the time I get around to installing my regulated return. I'm deleting the bowl, and was trying to figure out where to mount the post pump filter. Right now my plan is to move the pump back, but I might reconsider that if I could find a place to mount it and keep the pump in the same spot. Different options is always a good thing

I moved my fuel pump to the inside of the tank.
Best move I ever did for the truck.

Pressure is the same as stock, the pressure regulator is still in the fuel bowl.
What makes this mod so good is the total lack of any air introduced into the fuel stream.
REALLY reduces the amount of cackle. Idle is glass smooth.
