Fuel Pressure question and Leak???????

[vanrj1]

Ok, so driving home from car show today and my car stalled at a stop sign. I got it off the road and opened the hood and noticed a little gas leaking. got it started and it was running real rough and got back to my garage, then noticed it was leaking in three places. I shut it off and the fuel kept dumping in the front carb like there was to much pressure. Here is a pic where it was leaking. This is NOT my carb just used it for description. Mine is a New Edelbrock 500 cfm

Electric pump?

Electric pump?

No, It's Mechanical

Possibly a float stuck in the carb.

What's the best remedy for a stuck float? Not real mechanical when it comes to rebuilding a carb. It is only 1 year old.

Aftermarket pump? How many gph?
How long since it was rebuilt?
Maybe time for a rebuild?
(the pump plunger rubber gasket and airhorn gasket are included in the kits. Eddy's are super easy to rebuild)
but as ykf mentioned I'd also check the floats,
Best remedy (the right way)is to pull your air horn and check the float position,
BUT, (i hate to admit this lol) in the past in pinch I've tapped on my carbs to free up a stuck float, JUST to get me home.

Summit SUM-250014-1 80 GPH, Max Pressure 8 psi (could be pressure as eddy's like 5 psi up to 6.5). They have about 400 miles on them and about a year old.

you dont really have to rebuild an edelbrock carb when you open it up and look inside.no gaskets should rip and you can put it right back together.just pull all the screws facing up and a couple of rods like the one to the accel pump.its really very easy.could be some junk got into the carb.you will be able to see the needle and seats very easy and can pull them out to inspect easy as well.just take some pictures and keep everything organised and it should be no prob at all to take it apart.

Sounds like a plan, Thanks

Just keep in mind that the needle and seat assemblies and the floats are attached to the air horn (the top of the carb you're pulling off).
Also, Eddy carbs HATE excessive pressure, so you MIGHT be running too aggressive of a fuel pump for that Eddy carb. (Reg.?) Rule of thumb on Eddy carbs is; the least amount of fuel pressure that you can get away with, is best. (What I mean by "get away with" is; enough fuel pressure to provide your carb with the necessary fuel in all rpm's but no more.)
when rebuilding ANY carb, I always tend to keep a spare kit handy JUST in case you need a particular gasket, even when performing tuning, I always keep a spare kit handy. (Better to have one and NOT need it, than to NOT have one and THEN need it.)

Ok, I took the top off and adjusted the floats. They were a little off from spec's. I also noticed some very small debris on the bottom of the bowls. I cleaned them out and reassembled. It ran fine, my guess is that there was some blockage. Also I bought a fuel pressure gauge and it is running at 7psi so I should install a regulator which I have (A new Holley) and set it to 5 which Edelbrock site says is optimal.

Preach it Brother!! i cant count how many times that has bit me in the *** till i learned!!! lol

Lol, I usually have to learn things the hard way, and I def learned that one the hard way.

 

[vanrj1]

Seems like it is working ok after disassembling and making a few minor adjustments and cleaning. Also added a fuel pressure gauge and a regulator to keep pressure at 5psi..... Thanks again for all the input!

if you had a little junk in there you might want to change out you fuel filter to prevent it from happening again.

Always keep something preferably wood or plastic handled screwdriver with you to tap it pretty hard while its running. Float is stuck or small amount of trash causes it. Done it many times over the years........
