Very nice regulator for the price. Only problem is tightening fittings. There is no where to place a wrench on the body of the regulator. You need to use a vice, or pipe wrench which works but scratches the paint. But over all, very well built and does its job well.

I used this for a carb swap on a tbi 89 firebird, worked great to meter down the fuel pressure right out of the box. Quality is good, comes with instructions and mounting hardware. Looks good.
