Fuel Pressure Gauge

... a little advice on gauges and not to get to complex. Liquid filled gauge absorbs vibration the best on an engine and a snubber will stabilize the needle for a more consistent reading.

How did you think that one up?

Be prepared to buy a regulator. You'll find the stock replacements push a higher pressure than recommended, from 8psi to 11psi. Without anything to regulate the pressure, you will eventually experience flooding.

Hey Marlin, who's throttle cable is that on your car?...

So now the hunt is on for a fuel pressure regulator!!! I saw a holly one that wasnt bad looking. Long as it works. Just have to buy some fittings for it.

Was out and about and stopped at 3 different auto part stores. None had a 0-15 psi fuel pressure gauge. South orange county has nothing. Go figure?? Not driving to santa ana in the rain. Guess I just order one online. Think there would be a speed shop somewhere down here that had it.

How about a Plumbing supply for a hydraulic hose supplier ?

Jegs should have them as well as Moon.

Edit: If you are running an electric pump you should use a regulator w/ a return. Mechanical pump should not need this. (experienced opinion)

Yeap ordered reg and gauge from jegs. Price wasnt bad. I did find one at an auto parts and it was 60 bucks for a filled 0-15 psi gauge. Plus the reg was not there so I just ordered of jegs. How bad can they be. If I have any trouble with them I can junk them. But Im guessing it will all turn out fine and I will have it set up like it should be. Just stopped raining so kinda wishing parts would come in so I can do some late night repairs.

So I received the parts. Gauge was good. No problem with that. I did not like the regulator too much. It was one of the round dial ones that you click into place for the amount of pressure you want. I had everything on so I could check the pressure. Pressure was good, but, after a while it dropped and ran bad. I messed with it for a while, clicked it up a notch and it ran better. But then after a bit it ran bad again. I took the reg off thinking maybe its just a POS, basically did the same thing. I have a clear plastic fuel filter that I replaced inline. I like the metals ones but I wanted to see what the fuel was doing. The filter never fills up all the way and it doesnt really look like a lot of fuel is pumping into it. It stays the same (about half full) the entire time even when running so it looks like the pumps pumping gas. I get some backfires out of the carb so Im thinking lean. Not enough fuel. The fuel pump is new but that could be a POS too. Im kind stumped on what to do or check. I did all the electrical checks, to make sure distrib and alternator were ok. Seams to me the pump is not pumping enough fuel. Am I crazy or what? I drive it down the street not too far in case I had trouble. It bogged whenever I gave too much gas. Any ideas whould help, I have time to check things out this month. Please help!!!

What year car do you have? The early models had a fuel pickup that extended to near the bottom of the tank. It tends to rust and the pin holes let the fuel pump suck air.

...If The Pump can't Build and HOLD Pressure!
The Pump is BAD! As Husker said..The Pump Suction May be Blocked(Would explain the Air Bubble in the Filter) OR The Pressure is Leaking past Bad Fuel FLOAT 'Needle and Seats'! Might Explain the Backfire-ing!
What kind of carb are You running?
Have You Observed the 'Pump-Shot' Down the Throats?? Use a Flashlight a Mirror and a Helper! While Your there You can Verify that the Throttles Open FULLY!...

I'll bet there is NO Pumpshot because the Pump ain't pumpin! Find the Reason Why!...
