dellorto fuel pressure question?
 

So i just bought a gsl with 48dhla on an s4 6 port with the sleeves removed. The PO was running without a regulator and the car would bog. Its at 3.5 psi, so i went and bought a mister gasket fuel pressure regulator#9710 adjustable from 1 to 5 psi. I have been thru 4 of them and none of them are consistent. 1 worked but it leaked from the adjusting knob. The other 3 won't get my fuel pressure under 3 psi. I need it at about 2psi.it runs cherry rite there!

My question is what fuel pressure regulator is everybody using with their Dellortos?

i used a Carter pump with a Holley (1 to 4 psi) regulator when i ran my Dell'Orto.

im gunna look into that! i re-sealed the original regulator i bought and it works pretty good but just looks so cheap i know its set to fail in the near future. All other regulators were in the wrong range and none adjusted low enough to where i needed them but i am definately gunna look at the holley before this one fails me! Thanks! :icon_tup:

Don't use the Mr. Gasket piece of crap, not only do they not work they also restrict the flow
significantly. Ask me how I know :)

I use the holley 1-4 as well on my Dell. Setting it to 3.5 is almost more than the Dell likes.
Mine is around 3 I think. I say I think because the gauge is a liquid filled 1-15 and at that
low of a setting its not always accurate.

I adjust mine by engine sound. Get it good and hot and slowly crank it open until the idle
changes a bit and then crank back 1/4 turn and leave it alone.

mine seemed to be happy at around 3 psi as well. it took me a few weeks to accept it, but the fact is that's where the engine performed best in the lower RPM ranges.

fuel, fuel pumps, reg
 

I have a Dellorto Carb on a 1989 13B with the port sleeves removed. The car has racing beat header and exhaust, i use two 4 psi facet fuel pumps. They pressure regulator is set a 3.5. The car runs fine. if i didn't have two fuel pumps the car could starve after a few minute of hard acceleration. I think my Dellorto mauel recommended 3psi.

anyone got the part number on this holley regulator???? Is it the 12-804?
