fuel pressure regulator

[Jeff Geisen]

Plug the lines you have running into the jugs to test pressure statically.

what Jeff said.

You did make sure the bolts holding the regulator cleared the tank, right? The firewall is almost up against it. More than one person here has drilled thru the firewall into the tank without realizing it until the engine is back in and the tank filled.

post a PDF of the instructions or a link to them for the regulator.

My last name might be Kent but I do not have x-ray vision to see inside that regulator to see how the ports are plumbed. At least post the make and model of that regulator so we can try to find a set of instructions to answer your questions on why the flow is so uneven. For all we know one port could be regulated and the other unregulated or something like that.

I tried contacting them, but they seem to be phone oriented, fax too. So I will call them in the AM...

You know what I know now. You would think they would note any crazy features on the item page.... Port size is important, but not much else given.

thanks, I am off to bed, 71 year olds should not be up to midnight. We can read the manual in the morning. Took 3 or 4 minutes to find the manual.

Good luck sorting that out.

[malcolm2]

I thought i read that the 803 came factory set at 2.75 psi.

Plug both lines. Check pressure. Stop pump release pressure, swap lines do it again.

[malcolm2]

I did get intouch with Jegs today.... While plugging the lines may give me a reading, it seems that the only way to test is to hook it up.

Oh well, guess I won't know til I am done if it works or not.

Thanks for commenting.

if you want to test it, pinch each fuel line closed with something like one of these. I got mine at a Napa, but HF has similar. Then release one until a small trickle flows. The do the other so both are flowing. If it is set at the 6.5 psi the PDF and ads online say it is, you will need to adjust it down to maybe 3 1/2 psi or so. I think 6+ may overwhelm the needles. We used to set the race car to 3 - 5 max and those carbs were maintained in a pristine condition.

If you have not yet touched the adjustment screw, your pressure gauge should read 6.5 PSI. If not then the gauge may be suspect.

If one carb isn't getting fuel the problem is more likely to be in the carb than to be in the regulator.
