Gasoline pressure

[Otto]

Hi

When my gasoline pump stalled on my plus 2, i installed a Fazet gasoline pump. It's working fine, when the car is up and running, no starvation problems!. But i have trouble with flooding In the start up. I am suspecting the pump of deliviring to High gasoline pressure, and suspecting the needles in the webers to be to week or old to handle/ shut down gasoline.
I Think i have to put In some pressure regulator device.
Do any of you have experience doing so?
And what pressure is the Right for webers?
And what brand/ model of regulator would you recommend?
Would like to have a good qualaty setup.

Regards

I've got an electric pump on my Elan. At the time there were two pressures available, one for injection systems and another at a stated 4psi for carburetors. The workshop manual shows a maximum 2.5psi for the mechanical pump so I was hesitant at taking the 4psi as ok.

Once installed I also had some flooding so I rebuilt the carburetors with new needle valves and from internet searching found various recommendations for pressure, ranging from 2psi to 4psi. In the end I fitted an adjustable regulator after the pump which allows me to go from 1 to the full 4psi so I had the options covered.

It's been set at 2psi which seems to be working ok for my driving style. (slow)

Thank you for interesting answer. Sounds good with the variable option.
D? you remember what brand it is.

Hi,
It's nothing special or expensive, just a simple regulator that I bought from Ebay UK labelled as "Pro Flow" by Sytec which I'd never heard of until it arrived !

I'll try to upload a photo showing how it goes together.

ProFlow! What Hip hop musician wouldnt love to have such a device.

I've been using one of these - http://www.demon-tweeks.co.uk/performance/fuel-pressure-regulators/malpassi-filter-king-fuel-pressure-regulator-and-filter since I fitted an electric pump about 25yrs ago.

I've no idea what pressure its set to and it doesn't seem to matter - whichever end of the scale I set it to the engine seems to work ok, but I'm using it to feed Strombergs and they may not be as sensitive as Webers.

I seem to recall that the Webers call for no more than 3 psi. I had that issue back on 1972! when I put a fuel pump on my first Elan. Bought it at the local hot rod shop. It was meant for 4 barrel Hollys. Completely flooded the csrbs.

I have one of those Filter Kings's too, though mine is the 87mm one with six screws holding the pressure diphragm chamber on the top.

I don't know what it is set to as it was set for me by Vegantune of Finchley when they installed it, but robably about 2.5 psi.
