Maybe I should post this in the forced induction section, but anyway could someone please explain this.
-I am trying to test the fuel pressure I have at idle so I installed a fuel pressure gauge on the fuel return line just after it goes through the factory fuel pressure regulator and the then the hard line off the fuel rail finally connects to rubber hose.ing -The reading i get is only like 3-4 psi. It should be around 40psi. Its not the gauge when I squeeze the return line after the gauge the fuel pressure jumps up to 40. -I used this method to read fuel pressure on an fuel injected Isuzu I worked on and it worked great. Is the toyota celicas fuel pressure regulated differently?????? The car is running fine so I don't believe anything is wrong..... Help!!!!!!! |

You have to pick up the pressure from the high-pressure line BEFORE the regulator. After the regulator (return line) there is no pressure. -Doc -------------------- -Dr Tweak, 6GC's resident engine swap wiring expert extraordinaire Click here to see my swaps drtweak@phoenixtuning.com |
