Warning...fuel press. regulators

[thejum57]

Just a heads up to anyone who has a Purolator fuel pressure regulator....I had one on my J-10, because I have a Weber carb. They only like 31/2-4lbs. pressure or they run like %$#@ ! Anyway, they seem to fail, mine did and I couldn't find another one. Called the main office in Tenn., they said they are beging re-called, and stopped production a year or so ago. I went to the local Autozone, they have a no name brand right on the shelf. Hope this one works better!!! I was going bezerk trying to figgure why it was STILL running like &^%$ even after dropping the tank, and replacing the pick-up tube filter. I think I know why now!!! :rolleyes: Hope this saves someone a little agrivation!

Those are VERY DANGEROUS!!!!!!!!!!!!!!!!!!! Junk!!
I used to run one on my CJ and my wagoneer. Last summer I'm 4 blocks from home and I start smelling gas. I'm almost there I think, I'll keep going. 100 feet from my drive way it (smell) gets real strong. I pull in the driveway, shut it down, open my door and gagged from the fumes. I grab my fire extinguisher mounted between my seat and door. There are multiple heavy streams of gas dripping off my freshly painted 350 on to the ground. I pop the hood and there is gas everywhere bigtime. The manifold runners were full. I hose everything down and start searching for the leak. I could not find it. THANK GOD I had done a HEI conversion. A points distributer would have ignited that mess and there is no doubt my wagoneer would have burnt to the ground.
I bumped the ignition after another hose down and right from the center on the fuel pressure regulator behind the sticker shoots this huge pencil thick stream clear up to my open hood. I had it turned off just as the stream hit the hood. I almost lost my wagoneer that day. I still have the regulator in a ziploc bag at home. I took the one off the CJ right away.

If anybody reads this and is running one of these regulators, I STRONGLY recommend removing it TODAY if you like you're rig. The volumes of gas this spewed out will be more than a small fire extinguisher can handle. TAKE IT OFF...

I run a Holley presure regulator at 4 psi. I used a Purolator reg once...stressing once. Used the Purolator fuel pump also....again stressing once. Purolator stuff is crap.

... No fuel pressure regulator needed here! I run a red top electric Holley fuel pump. It is on the high side pressure wise for my MC-4300 4V but the pressure is slightly lowered by the fuel return line. This combo has worked for my ’76 401 very well for the last few years.
... I have put a washer with a 3/16th inch hole in the return line to adjust the main line fuel pressure

I've been running a Purolator regulator with my Weber since I installed this engine in July. I set it to 3.5 lbs, which is within the range recommended for this carb.

I've been constantly dealing with a lean running condition and occasional vapor lock. At first, I thought it was vacuum leaks, but I'm sure that's not the case any more.

I also installed a secondary (electric) fuel pump, and the problem hasn't been solved. I guess it's worth a try to remove the regulator.

... Pretty broad statement.
Does this mean you have tried every single product they manufacture?

Conjecture sucks.
How about 'some' of their crap sucks?

Any suggestions on how to reduce pressure without a regulator? I don't get the "washer" method you mentioned Don. These Webers are REALLY fussy! If I didn't spend so much on it, I'd replace it with a Holley 2 bbl.

I put in a Holley red top pump on mine,too. I can tell you from experience,though,it's *way* too strong for the 2150. I'm using the regulator that was mentioned in the first post. Right off the shelf at A/Z for less than $30. Seems to be working fine for me. And for what it's worth,I'd use Purolator products (especially their oil filters)long before I'd even consider buying anything Fram (again,oil filters) makes.

... The fuel return line can possibly bleed off too much pressure in a few cases. So I installed a small washer in the hose right at the third nipple to reduce the amount of fuel and vapor flowing back to the tank there by increasing fuel line pressure to my 4v carburetor. This way I could discard the fuel pressure regulator.

Holley Red Tops are a gyrator type pump and very smooth.

Purolator did make some very good oil filters.

I've been running a Purolater regulator on my CJ for almost 15 years without a problem. I'm not doubting what you say, but maybe just the newer ones are having problems. I've found it very useful when I'm wheelin off camber areas to damp down my fuel flow to 2-3 psi to prevent too much fuel into the float bowl.....................phil
