i need at least 80 psi, can a turbo pump do it for me?

 

If you're real lucky. According to the FSM, the TII should have about 70 to 90 psi of dead-head pressure AFTER the filter. Mine has 72 (with 12.4 volts). I have two others that both tested at less than 65 psi, but I don't remember what kind of voltage I had when I tested them.

My pump is 18 years old; maybe the newer ones consistently put out the specified 90 psi, but I don't know.

 

Are you trying to flow a significant amount of fuel at 80psi???
Then the answer is NO.

yeah, i got an s5 engine dropped into my s4, no emissions, strait fuel lines, and my old fuel pump only pushed 60 psi, i found a turbo fuel pump for 25 bux, and if that'll work then cool, if not ill get a walboro.

 

you do understand that as PSI goes up flow goes down, like WAY DOWN. why on earth do you "need" 80 psi??? i really don't understand that...

 

ben, i think you fuel pump is fine keep the one you have. try and find some new s5 injectors or take yours out and send them away to be cleaned.

 

Why would you think you need 80psi? Stock static fuel pressure is ~36psi and there's really no need to go much higher than that.

The only way you'll get 80psi out of a fuel pump is if you dead-head it (i.e. blocked off, zero flow), but this tells you nothing.
