Proform fuel pump?

[jkgts1]

Hi, I'm in the middle of doing the fuel system in my 74 260z that is going to have a 2jzgte swap. I have been looking for a lift pump for the surge tank, but I'm not sure what to use. I don't plan on increasing the HP too much in the beginning, I maybe want 350-400whp max. I was going to use the Bosch 044 for the primary pump. Does anyone have experience with the Proform standard pressure pump (#67380) for a lift pump? I've been trolling through the different threads, but still need some advise. I know some people say they use their stock pump as a lift pump, but does it flow enough or equal to the Bosch 044? I'm trying to get all my info straight, so I can try to do this right the first time.

 

Thanks

Proform is a Chinese brand. They are cheap. Many of their parts fail. Do you want that on your 2JZ? Just buy a Walbro 255 Lph pump. Likewise, the stock pump should work. You have to realize that the amount of fuel a pump will flow is totally dependent upon the amount of pressure it must put out, as well. A lift pump (from the fuel cell) to the surge tank is essentially at zero pressure (open discharge) and is therefore under very little load. A Walbro pump is under $100 and it's a set it and forget it situation (for a long time). Don't skimp on fuel; it's insurance for a forced induction engine.

You don't have to "match" flow between the lift and primary pumps. The surge tank is configured so that when it is full, the rest overflows back to the fuel cell. You want it to always be full. This is relatively easy since the fuel cell pump is in open discharge and flows a very high rate versus the primary pump which must feed the engine at ~60 psi +/-.

Cool, thanks for the reply.
