i have a fuel issue and almost sure its the regulator. in the next few days im going to pinch the return line to make sure my pump is still strong. i do have a pressure guage on the fuel rail.

im looking for a part number for an adjustible fuel pressure regulato to fit on a hsr... im not sure i have confidence in the one i purchased (holley) so another aftermarket one would be great.

its been awhile, is it possible to have my regulator screw facing outside. using the head of a nail sux.
