Fuel pump and fuel system ???'s I'm in the process of setting up my fuel pump system, and have a few ???'s
Donor engine 2002 LQ9 from a Escalade w/ a feed and return line
Recipients Vehicle 1991 Toyota Land Cruiser
The LC is fuel injected, I see three options for me...
1 stock 1991 pump About 45/50 psi
2 stock twin turbo supra pump about 50/55 psi
3 fit the correct GM pump
I see the LQ9 wants 60psi, if I use the stock GM pump do I need to use an additional regulator?
I have read my builds where they use the TT supra pump and they run fine
Can anyone give me do's and dont's before I buy a pump

I don't think that's your return line, that goes to your emissions canister. You should have a bleeder valve on the fuel rail itself where you can test pressure. I have a 2004 lq9 and as far as I know there is no regulator?
