Holley fuel regulator problem ?

[Kiel]

Hi.

Have problem with my Holley fuel regulator. The seat can not close 100%. Pressure rises to 14 psi. I have tried 3 different holley regulators now. But stil the same problem. I use a Holley blue pump and provides 14 psi. And it is a low pressure regulator 1-4 psi.
Drive not with retur-line to tank.

Hope that there are some who can help?

Check you have the right colour spring  or buy a better make of regulator. There are plenty out there. Bernie

That's not what you told me when I bought mine from you!

there have been lots of probs last year with holley regulators, my advice by a different one.

I can't comment on he more recent holley regulators,
but the ones tha I used through the nineties were trouble free.

The only problem I ever had was when crap caught in the ball.(stray aluminium shaving)
This made the carb pressure equal to the pump pressure.
...so if the ball is not seating correctly, due to shoddy manufacture, the symptom may be the same.

I think if you had the inlet an outlet port swapped it would do the same.(?)

You CAN buy different springs for the relief in the pump to try that.
...which may help the regulator do its job better.

Yes, there are much better products on the market these days.

I had a few Holly's and in the end replaced them with a Mallory, whilst there may be a big difference in price there's a massive difference in quality.

after years of fighting with my Holley "fuel T" I discarded it and replaced it with a Malpassi. Set it once and haven't touched it in more than a year now.

hi.

Has borrowed a Mallory regulator, and will try it tomorrow. But it goes from 4-12 psi. Will also try to take a bit of pressure of the  blue Holley pump , to 7 psi, instead of 14 psi.

I runs with 300 original needle valves.

Hove must pressure do in running (psi)?

hi.

Have tried Mallory regulator today, and it seal 100% , but can not get the depressed without 3.5 psi, and then the carburetor starting to overflow.

So try to buy a filter king (Malpassi) regulator 1-5 psi.

Are there some who know about it have to turn in any particular way?

Will like to have it fit on the firewall !

I am running the Malpassi Filter King reg on my car. (see 48IDA linkage thread from yesterday). I "shock" mounted it to the Berg linkage angle-bracket just above VW oil filler and next to alternator. I'm running 8mm fuel line, Holley red pump and have it set @ 3.0psi. No reason to goof around with it now for over a year.

Hi Stagger Lee

Thanks, will try it.

Hi Thomas,

What is your problem? That the needle valves do not close or that the regulator does not work?

If needle valves, have you checked your float height? Glass needles? If so, good luck with getting them to seal. Bigger needle valves = more area = harder to seal = lower pressure to seal = no problem since they flow more. I had to turn the pressure down to 2,3-2,4 psi to get my 3.00 needles to seal.

Hi beetle bug.

My problem is to have the regulator to seal. The pump pressure rises in the carburator, to what the pump can deleve in pressure,
( blue holley pump  14 psi ). begause the regulator not seal.

But will try to reduce the pressure to 7 psi in the pump. JPM tricks.

I run with 300 originale needle valve.

Have just order a fliter king regulator, so i can have the pressure set at 2-2,5 psi...  I hope will help me.

The 3 new holley regulator i have bought is going to stay forever on my racer shelf ! picture vill come...........

i've just had exactly the same problem with a new holley reg im using on mine, mines a draw through turbo setup tho and i have 1 rising rate holley reg which rises with the boost pressure, and a second holley which caps the pressure at 5 or 6 psi, basicaly so it gets enough fuel to the float bowl when the turbos drawing hard at it, without it rising too high and flooding it! the rising rate one is new, and the second one looks older, guess which one wont hold the pressure of the blue pump!..... yep the new one! its seems to do it totaly randomly too which seems odd.
