Fuel systems
Ok guys here is whats up. I have 3 things
1. I have heard our cars have a secondary fuel pump mounted inside the engine compartment. What is this part called? and do they burn out?
2. What is the proper procedure for testing fuel system pressure? How much do test kits run?
3. What should proper pressure be at?

No secondary pump on MPFI motors.
The kit to test the pressure on our cars cost me $20 at Autozone and it has the little connector to screw onto the schrader valve by the back of the intake plenum.
Proper pressure should be 35-40 psi if i remember right
