My son and I are resurrecting a 75 280z that has been sitting for 6yrs. Now that it is running, it leans out under load. (No power and backfires). I am trying to find out what the fuel pressure is supposed to be. Can anyone help me?

According to the FSM, the fuel pressure should be 36.27 psi. The fact that you car has been sitting for 6 years likely has caused restrictions in the tank/lines due to the sediment build up from the old gas. I went through the same thing when I bought mine. You'll have to clean out the lines and clean or replace the tank.

I need to replace the gas lines on my 72 240Z. Can anybody tell me what to buy for:

Gas Supply:

Gas Return:

Fuel Guide Valve Line;

Thanks, zdisease
