Adding pusher pump on 2005?

[Blacksdieselhp]

My truck has the in tank fuel pump. Do i need to drop the tank and do away with the stock pump or just run another hose in the tank and tee back into the stock fuel line? That way I would have a backup pump also. What do you guys think?

Good luck! I asked this same question about 6 montha sgo and got NO INFO!

I'm interested in doing this as well on my 2005 with the in-tank pump. I think what I want to do is add an external pump and keep the stock internal pump. I'm unsure how to do it. Does anybody make a kit?

First off, in my opinion, the in tank pump is too restrictive to suck thru for high hp applications. So, I dropped the tank down and out in a bulkhead fitting and run -8 line to my pusher pump. From there it is -6 line all the way to the CP3. Just before the fuel filter, I installed a T valve with the factory pump feeding in one side and the pusher coming into the other side. I keep the valve switched to the pusher pump and popped the relay out of the fuse box to shut off the in tank pump. Now, if the pusher fails, all I have to do is switch the T- valve to the intank pump and put the relay back in and go.

thats correct, the stock lift pump is too restrictive, your best bet is to bypass it alltogether. :-laf

Let me just say... Thats is an awesome setup. Kudos to you for that idea!



Like a RASP, but less money - And still with "plan-b" feature!

Why thank you. I was actually thinking about putting an electric solenoid valve in place of the T valve so I could switch it without getting under the truck.
