Gas on Air cleaner??

Gas pouring out of Carb??

Been trying to figure out a bogging issue when I took off my air cleaner and it was soaked in gas...it poured out. What would cause that

EDIT:

Turned on my fuel pump with the engine off and gas is just POURING out of this

any ideas?

Too much fuel pressure and/or your floats are set way the hell too high and the bowls are flooding.

Bad, worn, dirty fuel inlet needle. Or, some dirt may have gotten in there, and is now gone. Don't use stock or the cheap fuel filters.

Or, your float level is very high and you took a corner too fast.

Or, you have a fuel leak in the fitting or fuel line.

I still remember when I switched the jets on my Holly in my Olds (way back in the day ) and I was in a rush and didn't fully tighten the fuel clamp. I go to the mall, went shopping, come back out, got in my car, and I could smell gas big time. There was a little leak. When I was driving, the fumes never made in inside the car. After I parked, some gas leaked on the manifold, evaporated, and made such a smell that my eyes were burning when I went inside the car.

Moral of the story: Double check everything, don't rush, and don't use old cracked fuel lines. And, Joe did MANY stupid things in his life. I hope that I can prevent at least some others from repeating my mistakes.

Don't forget, everyone makes mistakes!
The smart people learn from their mistakes.
The morons don't and keep repeating them!

Yup, the needle on your fuel inlet valve isn't fully seating. Or, the float went bad. Both are very common for a number of reasons.

As said, dirt is the most common.

Or, if you have a plastic float, it may have started to disintegrate.

OR, your metal float may have a leak in it and is no has gas inside. That's easy to see. The float no longer floats. That's also common.

Or, you put the carb back together and bent or didn't align the fuel needle valve.

BTW: Been I've there many times! My Vega had a munged up valve seat assembly. The carb would work for a while, then the needle got off as enough of an angle and would stick open. In case you didn't know, that's what they invented hammers for. Hey, it was a 4-cly Vega and I was a very broke college student!

tapped the float and it quit doing it. Now my new plugs are soaked in fuel. Just take them out and let them air dry?

Yup, let the plugs and cylinders dry out.

NOTE: You really should find out WHY the needle valve stuck! It will happen again! Trust me on that one!!
Remember what I wrote above!

It might be a dirty fuel filer, or it might be a bad needle valve and/or seat, or bent needle valve assembly. Regardless, the problem is likely to reoccur. My guess is that it happened before and got gas on the air filter. Then, you went over a bump, or something, and the needle valve reseated.

You do realize that you're asking for your engine and car to catch on fire with gas just pumping out onto the manifold, don't you?

Get a Holley rebuild book. Get one used from amazon.com. You should be able to pick one up cheaply. Also, check on the web. But, IMHO, NO web site is replacement for also having a Holley rebuild book!

If you don't take my advice, that's your choice.

Good Luck!

BTW: My vega's carb had a worn seat and needle. But, it was an in-line 4 with the carb hanging off to the side. And, just about all of the gas would go right into the carb when the valve got stuck. It had a worn fuel pump, small fuel lines, and an old semi-clogged fuel filter. Any leaking fuel that didn't go into the carb, wouldn't even go on the exhaust - it would just go in the ground.

So, just because I was semi-foolish/risky with using a hammer to unstick the carb in my Vega, that doesn't mean that it's at all safe to have fuel leaking out of a 5.0 carb. As I mentioned with my V8 Olds, I made damn sure after that fuel leak not to let one happen again in the Olds.

I bought the carb brand new in December...Holley 650 double pumper...and now its just April and this is happening. Its past the 90 day warranty but the store manager said he's help me out.

Im just going to have him order me a new one

It was probably just some crap keeping the needle from seating. Do you run an inline filter before the carb? If not you should...this same thing happened to me but it was in the rear bowl.

yea its right under the hood before the carb. Now with all new plugs, its misfiring at low rpms (most noticeable about 1500) but smoothes out when I mash the gas further
