I got a high pressure Fass pump with some stuff that I bought from a guy I thought it was just a pump without the filter. Turns out that is not the case. Can I run this on a Lbz instead of a lift pump? And if so where do connect to, I was told it goes under the hood somewhere, fuel rail? CP3? I'm lost. Thanks

That is a lift pump

i would probably put it on the frame somewhere ,It ties into the 12mm fuel line under the truck to precharge the cp3

try a search, or in the diy section

try fass website for install instructions and you should check your parts list vs what comes in the box

have you connected a power supply to see if pump even runs?

I think this is the one where he is missing half the lift pump.

Post pic of said pump.

I think you should contact seller and get refund. You are missing half you pump if it is the one I am thinking about. you cannot make it work....

I don't have a picture of it but the guy said that this one went under the hood on a wide open throttle switch and he was running this along with the other fass setup on the fuel rail. I thought he said this pump was capable of like 100 psi? I don't know if there is any truth to that though.
