An old brand of universal fuel pump, looks to be a solenoid pump. The other is like a roll-over valve or something. My car had one pre-bridgey fuel system. I removed it, never heard of it being used before.

Do you think I should order a new fuel pump. This one It has gas coming from it, but it feels like its not pumping enough. Bowls are filling up however when I start to hit the gas it feels like it empties it to fast. I remember on my old Rx-7 that the fuel filter looked more full in the engine bay. This one however looks as if its just trickling into the fuel filter. It'll start strong and slowly go weak. The vent is actually hooked up to that solenoid Didnt have a gas tank when I bought it -_-

Starting out with decent pressure, then dropping off is pretty common with these, particularly in a return-less fuel system. As they get warm, the PSI will drop. They get warmer, faster, when run without any type of return line, due to less flow thru them. The fuel flowing thru is what helps keep them from getting too warm.
I agree with Jeff. Too small for feeding a Rotary, especially one that is driven beyond the "granny" stage.......

Used this one until I switched to the holley. Mounts very cleanly near the fuel tank, looks stock and mine ran perfectly for over 10 years. I think it probably couldve fed the holley just fine, but I got a smoking deal on a holley blue.

Srsly try that little solenoid pump. I can dig mine up out of the parts shed and dust it off if you want lol. I'm 100% certain that little bugger still pumps, even 14 years after I bought it.

Yeah, the little holleys are cheap and can be rebuilt for under 10 bucks. Theres a few different kinds out there, you should try to locate a bypass regulator to use the stock bypass lines on the car. UNLESS your nikki still has the bypass built in. Then you could go with a dead-dead regulator.

Theres some of your choices, but I ran a 803BP with my nikki@4 psi
