Okay, after reading the reviews of the Mr. Gasket 9710 Fuel Regulator I was more than a little apprehensive about purchasing this unit. I am using this regulator with the Mr. Gasket 42-S low pressure fuel pump, which pushes 2-3.5 psi @ 48gph. I wanted to reduce the pressure down to as low as possible for use with a 1750 watt portable generator that has a very small Mikuni carburetor, just to be sure that I didn't flood the thing out. Anyway, I went ahead and took a chance and picked up this regulator at my local Advance Auto....and I'm glad I did. It worked perfectly for my application! My portable generator now draws fuel from my RV's fuel tank with no over pressurizing or flooding of the 3.5hp Briggs and Stratton engine. There is no longer any need to refuel the puny 1 gallon tank on my generator every few hours. Now, I have only bench tested the regulator. I have only run the generator for a brief time to make sure that everything checked out, so I cannot attest to how this thing will hold up. All I can tell you right now is that this regulator did what is supposed to with no leaks or problems.

One note: to confirm another reviewer's comment, as soon as you pull the unit out of the package you MUST check the screws that hold the housing together. A couple of mine were loose, but about 30 seconds with a #2 phillips took care of that problem.

These "dial" type of regulators used to be of better quality back many years ago when they were not made in China, but now days every thing is it seems. Use available discounts when possible, in my opinion not worth [$], only bought this using an Advance Auto Parts promo discount, and needed it to regulate the pressure of an electric fuel pump added to the car before I purchased it. Mine does not leak, I sealed the fittings with a little Permatex #2. Looks good in engine compartment, but on close inspection the finish is not quality. Again, our Chinese imported parts. I would only recommend to a friend if they really needed it to get a vehicle on the road.

Attached it to reduce mechanical pump pressure from 7 to 5, when dialed in to 5 we still had 7 psi, had to set dial to 2 to reach 5...will return today.

Comments about Mr. Gasket Fuel Regulator:

Regulator is very simple to install and even easier to adjust the pressure settings. According to fuel gauge it will not dial down to a precise pressure but will keep it manageable for most carbs

Comments about Mr. Gasket Fuel Regulator:

This is one of the worst products I've ever used. Ive got a few things from Mr. Gasket in the past, some of them didn't perform as well as I would have liked, but they all usually at least work. I added this in conjunction with a 5psi MAX fuel pump and a weber carb on my truck. The minute I fired the pump up, it leaked out the sides EVERYWHERE. I thought it was possibly a bad unit so I exchanged it. The next one did the exact same thing. I tried 3, all new, they all did the same. I finally gave up!

            Dont bother with this regulator! I bought one to put on a custom VW trike. My pump puts out 5-7 PSI. The carb system i have runs good on 3.5psi. I bought this to lessen the flow out of the pump and right out of the box i had a issue. The diaphragm inside was folded when installed so it put out max PSI regardless of setting. I had to take it apart and fix the diaphragm. It worked fine for a week or 2 then every so often it would act up and either the fuel will go right through it non regulated or would get blocked due to the faulty diaphragm.

            I read the reviews but couldn't believe that the product was as bad as people said. IT IS THAT BAD!! Mine didn't leak as several people experienced. However, after only about 10 minutes use, it simply quit regulating. The measured outlet pressure of my electric fuel pump is 5.5 psi. The measured fuel pressure after the regulator is 5.5 psi--at any setting. That is absolutely inexcusable. I hope that you will learn from my experience and others. Save yourself money,time and hassle by just leaving this junk in the store.

                Ok, there are alot of reviews saying this product leaks, even when fuel pressure is low, and id agree if you just throw this on after buying it, it would, but i noticed when ir eceived this product that 5 of the screws on the bottom holding the housings together were loose, if you spend the couple minutes to tighten these screws pretty tight before install you should have no issues, been running it for almost a month, fuel psi is standing still at 4.5 psi when it used to be about 8-9. Id say if you tighten those screws before install all should be good.

                    I installed this on my T-bucket hot rod, which runs a stock GM fuel pump and a Rochester Quadrajet carburetor. After just a 5 minute ride, this regulator had quit working and was running full fuel pressure to my carburetor. Don't waste your time and money. Spend a few more bucks for a quality regulator, if such is to be found. I would not even recommend this to an enemy !

                    The regulator does not do a good job of regulating the fuel pressure. I had another one on my car and it worked fine till it started leaking. I use a fuel pressure gauge and it's not close to what the gauge reads. It looks nice and will do for a replacement, the price for it in my opinion is too high for what the product is supposed to do. And do know what I'm talking about too, Retired drag racer.

                        A:

                        I'm happy to help, Gordon! Holley has a few regulators from their HP Billet Carbureted By-Pass Fuel Pressure Regulator line, such as Part No. 12-841, 12-845 or 12-842. These regulators are not available on AdvanceAutoParts.com. I suggest speaking with your local Advance Auto Parts or CARQUEST store for availability.

                        If you prefer another brand of regulator, looking for a by-pass style regulator for carburetor applications will help you narrow down your selections.
