Holley fuel pressure regulator issue
 

I was flushing the lines on my Camaro when I noticed a fuel leak from the bottom of my new Holley big port regulator. The fitting came with the kit, everything was tight. I even used paste after trying first with teflon tape on the NPT coming in from the bottom. Never run into this with a regulator, was getting late called it a night. Could it be a cracked fitting or cracked regulator. Anybody ever had bad regulators or fittings out of the box? Gonna get a fitting Monday at the local speed shop and start there. Nothing was over tightened, put several on in the past. Thanks for any input.

Not sure on the holley, but on the MagnaFuel and Product Engineering ones that I have used, the fittings require an O-Ring to seal up. Worth checking out if you haven't already.

I bought a Summit branded (remanufactured Holley regulator) and right out the box it had a pin hole in the casting. As soon I turned on the pump it had a tiny stream that shot out about 8 inches.

Regulators are thin at the threads and will crack at the threads if they are tightened very much.

Send the Holley back and buy an Aeromotive. Good quality stuff.
