I ran my camaro on the dyno today, and it was wierd, A little gas came up threw the vent port on where the charcoal canister used to be. It used to be TPI, but switched over to carbed.

Any help would be appriciated.

 

Qjet? That big 3/8" hose nipple on the top/front of the carb that points down at a slight angle? If so, that's a bowl vent for use with the stock charcoal canister. If you don't have a charcoal canister or you don't have a vent hose hooked to that fitting, put a plug on it. There are many other places on a QJet for venting to take place.

Chances are that some fuel splash inside the bowl at WOT (where there is a lot of fuel flowing through the inlet valve) sneaked it's way up through that vent. Shouldn't be much unless maybe your float level is too high.

 

No actaually, its a mighty demon 750CFM.

It comes out the line comming from where the fuel and return lines are....

 

coming out of the port on... the carb?
or the fuel pump?
vent port where the fuel and return line - that throws me.

What was the dyno results?

do you have a pressure relief on the gas tank? electric fuel pump, or removed and using on block mechanical?

 

Okay, right by the driver side wheel well, yo have your fuel lines, You have a Supply, return and a vent line that goes to the charcoal canister, that line is where the gas was comming out of.

Its a electrical FP, with a pressure regulater....

 

Sounds like it might be building up pressure in the tank.

 

Sounds like you need to put a charcoal canister back on it.
