Fueling & Injection - Fuel pressure gauge on front of rail.

Does anyone know where you get those fuel pressure gauges that screw on to the end of the stock ls1 fuel rail? Normally a plastic cap goes there but I have seen guys that have a gauge screwed on in that location.

I think I had metco fuel adapter with autometer digital gauge. you must remove fuel pressure spring under cap for everything to work

Excellent thank you.... that took two seconds too find online as well.

We also stock the correct fittings for this.
