Answer 1

Most fuel pumps are electronically controlled. The 4-6 psi range is the operating pressure of the pump. If you're car requires a 4.5 psi pump, this one will work. However, make sure that your car does have an electronically controlled fuel pump and injection system.

Answer 2

don't know what your doing .but rule of thumb is manual Fuel pumps for carabator is 6 to 9 pond of presser . Fuel injection is 50 to 90 psi

Answer 3

I dunno but I'm guessing there is some tolerance. Hook it up and see if it works. Or just get a used pump on Ebay for a few bucks.
