Can someone tell me how to increase the fuel pressure on my 87 LB9 IROC? I know that I need a new fuel pressure regulator but do I also need a new fuel pump? If not then where does the fuel pressure regulator go and how easy is it all to set up?

Also, I read a tech article and it says you should fit a pressure guage, is this essenbtial?

Finally where can I get the pest parts for the job and how much will it all cost me?

Thanks for the help

Look a few pages back at one of my posts or elsewhere Vader has posted an article about how to convert a stock fpr into an adjustable. You need a guage if you want to know what the pressure is.

I think there's an article on converting your stock FPR into an adjustable one in the tech articles section. The pressure gauge will fit on the schrader valve on the fuel rail.

Look at the article for the homemade afpr. You can buy a FP gauge at Lowes for $7. Don't waste your money on the Hypertech or Accel one.
