Hi,

I am using a holley fuel pressure regulator, since I left the electric fuel pump running last year and it filled a cylinder full of fuel...
I bought the holley fuel pump regulator off ebay, but no instructions came...
so I just screwed the adjuster screw right in....
it has seemed to be OK....
but I noticed fuel had leaked out of the accelerator pump
on top of the fuel bowl a few days ago.....
so maybe I don't have it adjusted correctly....
anyone with any info appreciated...

not exactly sure on the holley, but i can ask someone tomorrow for you....

any ways, on the mallory one that i use, which is the same principal with spring and diaphram, turning the screw OUT gives less pressure.(less spring pressure holding the diaphram down thus relieving earlier?) an in line guage would start eliminating your problems Lee.

1 3/4 ----3 pounds is plenty of pressure.

perhaps you might try turning the screw back out and seeing if the motor gets starved?

i will check on the holley tommorow tho.

If you left the adjusting screw as you got it it was probably preset way too high as holley carbs run higher fuel pressures, like 7-9 psi i think. get a gauge and check it, and wire your pump up to an ignition power source so you dont have to remember to turn it off!

I run one but I use a gauge which makes adjustment simple. Be aware though that there are two different springs available - I use a holley blue pump, but used the spring suitable for a red pump since I needed much less pressure than what the blue pump puts out. The only really way to know would be to add a gauge (I think about $20 from memory).

I'm guessing you mean with the ignition off?

You do know that you are required to use a tachometric relay when an electric punp is fitted don't you?
When no signal is recieved from the dizzy it will cut power to the pump.

the other trick is to use the charge or oil pressure light to control a relay

the old gemi's used to use the signal from the alternator spinning over too which is another method

Im looking around for a good boost sensitive one for the new blow through turbo project im starting anyone know of a good one?

My electric pump is situated under the fuel tank and can be switched off via a switch under the dash...
Its connected to the ignition.....

but when it filled the cylinder with fuel i was still doing some wiring and the pump was left connected to power.

When I turn the ignition on, if the pump is turned off an Amber lamp on the dash lights up....

I've screwed the adjusting screw in about half way...
all I can do now is drive and see what happens....

I haven't heard of the other types of wiring..,.
and I don't have a fuel pressure gauge...

thanks for Your comments

Lee
