I was checking out my fuel pump in my 305 87 iroc, there are to lines for fuel to be pumped out of it. Well one of the lines is stopped with a rubber cap and the other runs up by the carb and is Yed off to first and secondraies.

Would car run better if i ran a second line to the carb? or does it not matter. I am also having problems with the secondary float getting fuel could this be causeing it?


I know i am a newbee but please help

 

Stock there should be 3 fuel lines, 1 runs to the charcoal canister, 2 is a feed line to the carb, 3 is the return line back to the tank. Are you running a stock carb or aftermarket? Can you get us a pic of this?

 

There's no line to the charcoal canister on a stock pump.

How is the rubber cap held on?

 

Yeah, no charcoal canister line on the pump itself, sorry

 

It is an aftermarket summet 600 carb... it is a rubber cap can't think of what it is called but u screw it in and the ring gets bigger and smaler... the fuel pump to my knowlage is stock

 

Ok, the capped line is a little smaller than the one running to the carb?

 

Yea the caped one is smaller

 

That's the return line to send excess fuel back to the tank. With that capped, the internal regulator in the pump can't function and you're getting full flow up to the carb and it's flooding.

 

Yea just check and you r right found line it should run to

 

The quiesten then I wanna know is why didn't who ever hook itdidnt do it right

 

Maybe $5 of 1/4" fuel hose is too much for some people to spend. More likely it was removed under the misguided assumption that it was something to do with "emissions".

 

I went and got a hose for it, carb is off but still runs way better then it did before... thanks for the help
