Weber DCOE spraying way too much fuel...
 

This problem just started after I changed the fuel filter.

What would be the main cause of this and where would I begin to look into how to fix the problem? The car will start fine, but within a few seconds of running fuel will just start dumping out of the spot where the filter bolts up all over the housings. The car only holds idle above 1400 RPM. If you adjust the idle any lower or mess with the mixture screws it will start shaking back and forth and stall out. I got scared it would drip onto the exhaust manifold and ignite a fire so I shut it off.

I'm using a Holley 4-9 PSI fuel pressure regulator and it is set all the way to the bottom setting. Why is it getting so much fuel??

If you turn the key to ACC and let the Holley electric fuel pump run for a few seconds it will start dribbling out of the jets and pool up inside the carb.

I'm really getting frustrated with this Weber carb and the pressure regulator. I have 2 stock Nikki carbs and a stock manifold so I may just return it to stock. I can just run the OUT line from the fuel pump directly to the Nikki without the Holley fuel pressure regulator correct? Suggestions?

Your floats are probably stuck down. That's happened with mine several times. Do you have the plastic floats? They seem to be more prone to doing it. Take the float bowl cover off and try to hold the floats up as you put it back on. I've used a flat-head screwdriver to help.

does the FPR you have go any lower than 4 psi? webers like 2-3.5 no more.

Ah, yeah, didn't catch that. Also, those Holley FPRs are terribly inconsistent. Sometimes they work, sometimes they don't.

I was thinking the same thing. I've been told to run 2.5-3 PSI and then people have told me 4.5-5 PSI. I figured 5 PSI would kill my MPG drastically. It feels ok when you rev it at the current setting, but let it drop down to idle for a few seconds and try to rev it and you get a shake shake shake then a raspy rev. Too much fuel...

I noticed that it wasn't wanting to get much fuel at all yesterday so i jacked it up, looked at the fuel filter, and noticed there were large pieces of sediment in it. I also noticed that the line before the filter had pressure, whereas the lines after the filter barely had any. I changed it and then it was like niagra falls.

Is there an inexpensive regulator that will do 2-3 PSI that you could recommend?

The Spectre/Mr. Gasket/Purolator regulators (all the same thing) seem to do their job fairly well.

Are those all sold at Autozone and places like that?

yes.
