DO IT RIGHT AND IT WONT LEAK
As you may have read others say that this leaks. Well I'd like to say they're not doing it right!!! As a mechanic and DIYer I know that every fuel/oil/water/brake line you ALWAYS use thread tape! anything under pressure you use thread tape to prevent leakage. I have this in my 78 Mercury fuel my Aces EFI throttle body on my 403 stroker and NO LEAKS. constant 60psi all day no leaks. Do it right and it will work amazing!!

Works
I used this to adapt a Jaguar 4.2 V8 for a return style system. Holds constant 60 psi base pressure, does what it needs to do. Like most adjustable EFI regulators it will not hold key off pressure so if that’s important to you buy an inline check valve. The NPT fuel gauge as installed leaked, teflon tape seals it up. Excellent product for the price.

Doesn't Work, Breaks Quick!
Not as described. This product does not go from 0 to 100 psi. it goes from 15 psi to 100. if you lower it more than this, it hunts and hunts and is not good for the pump, even with returns plumbed well. the hoses are nice and cool, easy to cut and use hose clamps on, but the metal will cut you. After taking apart the check for the return was broken inside. Junk

Worth more than you will pay
I’d put this little regulator up against any of the higher dollar ones on the market right now . I’ve bought regulators from much bigger names and they were always problems with leaks and casting issues or the gauge was junk. Out of the box this worked , didn't leak and was accurate and consistent even after 50k .

Fuel pressure regulator kit
Great kit, priced right and works well! Use thread sealer and tighten a bit to seal. But after some tinkering which is to be expected, good results. Jimmy, Making it work

How to make it work for a Carb
As other customers stated, This will not meter down to zero. I purchased for a carbed engine with a 15 PSI pump. I could not get it to drop under 15 psi, no natter how I ran the fittings. I ended up taking the housing apart (4x 4mm hex bolts) and cut down the spring approximately 1/3. I put back the 66% spring and I was able to get it down to 6.5-7 psi which I can live with. The fittings are good to go just be sure to have the o-rings on the ORB end and use fuel safe pipe tape and you’ll be good. All in all, well worth the price if you accept that your going to have to make it work.

Does not regulate fuel. Screw turned all the way in or out, my fuel pressure is the same.

The product advertises 0-100 psi but it cant even go lower than 20. The construction is decent and would maybe work for EFI application. Not suitable for a carbureted engine.

Terrible regulator. Will not adjust below 45 psi.
