I have a fully modded 355 TPI. Afr's, Xtreme cam , 10.5/1 compression, longtubes, etc. When the car is idling we upped the fuel pressure to around 42 psi, but as soon as you start to rev the car it goes down to 35-36psi and never goes pass that all the way up.(We reved it until about 4k) I have 24lb SVo injectors and assume that the fuel pump can just not keep up. Where can I get an inexpensive inline pump for my car? What do you recommend?

Thanks

Chris

 

Also....would you recomend changing to a better inline pump or changing the intake pump(big pain)

You could go with an inline pump, however you would still have a half dead pump in your tank, restricting the inline one. I changed over to the Holley 255lpr in tank unit, it will supply about 550-600hp.
