Fuel Delivery (Pump) Question
So, I started the basic tune-up last night. Left with just putting on the new plug wires. Just one thing I was kinda curious about.
When I removed the fuel line at the carb to replace the filter (fittings were EXTREMELY tight), there was virtually no fuel in the line or the filter - - nothing spilled out as I expected. Is this normal? The filter was also quite dirty. The main reason I am doing the tune-up is the extreme rough running of the engine which just started recently, and came on quite suddenly. The engine lopes and sputters badly at idle - almost feels like a "low fuel" situation. So when I saw the "dry" filter condition, I thought could my fuel pump be going out as well? I have had suggestions that my fuel mix is too rich, which could very well be, and I'll be looking into this as well, but I'm just trying to cover all the potential bases. I'll finish the wire installation (hopefully tonight) and see how she runs, but I thought I'd get a jump on asking this question. |

Re: Fuel Delivery (Pump) Question
i'd change the filter for sure,there cheap.as for no fuel when you removed line,that's not abnormal.if you want to tell.put the carb end of fuel line in a coffee can or pan whatever will fit and bump the key a few times.you'll see if you got fuel flow.

Re: Fuel Delivery (Pump) Question
I am kinda having the same problem. I was doing a tune up on my 81', I put on one of those Mr. Gasket chrome and glass filters near the carb. With it just idleing the filter is full of gas, crack the throttle a little bit it sucks the filter almost dry and barely purculates any gas into it. Let off of the throttle and it fills the filter up again. I think I am going to put on an electric pump this weekend.

Re: Fuel Delivery (Pump) Question
The fuel lines from the fuel pump to the carb regularily go empty, when the motor is shut off. Part of this is due to the heat of the engine causing a vaporization of the fuel and IF you happen to have the return line from the fuel pump to the fuel tank, then the rest is going back there. I have a glass fuel filter on my truck and it is empty most of the time, until I crank it over.
