Do I need a new fuel pump and AFPR

[wtkaos]

I have a 95GT stock with a full MAC exhaust (with cats) and a cold Air Intake. I'm installing GT40p heads and ported stock intake and 1.72 Roller Rockers. Do I need a adjustable Fuel Pressure Regulator and/or replace my stock fuel pump???

any help would be appreciated.

thanks

I wouldn't say either are absolute requirements but you WILL benefit quite a bit from BOTH. The Fuel pump will add peace of mind...knowing that your car is getting the fuel it needs. The AFPR will help greatly when it comes to fine tuning the setup. I would have to HIGHLY reccomend both as they are valuable mods for little money. Make sure you get some sort of gauge to monitor your fuel pressure. A standard underhood one is just fine.

Thanks for the advice, I had a feeling I should get them.

Just to back up ryclef. I have the basic bolt ons (stock pump and FPR at the time) and when I did TFS heads/1:7's and stock intake I did a few dyno pulls for shits and to see how the a/f was. It came out pretty lean. Like 15:1 from 3600-5400rpm .

FYI, Accufab makes a nice AFPR.
