In need of an overflow valve for p-pump; preferably newer style. Also p-pump washer an nut.
 
Look up tork teknology they have the best valves for cheap,I run both the 60 and 70 hp valves on my truck and love them!
 
I have the 075 and I'm making to much fuel pressure have to back it off a little They deff work
 
I don't see how you could have an issue if you know what it is. Its just a fixed orifice size. If you're injecting a lot of fuel then you'll still need a good pump, because your pressure will always drop. Its not a regulator.

Pump work and injector size? I idle at 48, and can pull it down to 35 with raptor 150.

i run a tork Tek 75, pressure is the same at idle and WFO.......3 dyno runs and my fuel level gauge drops over a needle width :hehe:
 
i was running the 75 on the street, that being said..i don't know if i would recommend it to most people do to the low flow through the pump for cooling reasons. big modded pump, injectors, not that friendly of a street truck maybe
 
Ya the 75 for my truck makes crazy pressure I think it's to much at idle from what I have seen from pump builders gonna buy the 60 next

I know I don't have enough pump LOL. But my pressure stays over 35 so I don't care.

I thought 75 was the street one? What's the 60 considered for?

75 is full race, it has like a .030 hole for return out of the pump (almost dead heading the pump)

the 60 is like a .100 orifice for more return and flow through the pump to keep it cool

(don't quote me on the orifice size they are just for reference)
