Adjustable Fuel Pressure Regulators

[CrUZida]

Does anyone make a stock replacement with a built in gauge?

ie, unscrew stock one, couple of new washers, install aftermarket one, and bam, done.

Sard sell conversion kits for common engines, eg 1JZ/2JZ, and I think they also sell screw-in gauges. Should be pretty close to plug and play.

Turbosmart also make adapters that allow the use of aftermarket FPR's.

I've got one with a Sard FPR with a turbosmart gauge waiting to be installed.
