Fuel leakage

I was wondering if and if so how anyone here has delt with their fuel line draining back into the tank. I believe that their were some "Saucer" things originally installed on the fuel lines that inabeled the fuel to flow back into the tank but, I know that mine are gone. Anyway, without moving over to an electric fuel pump, how does one go about putting a stop to the fuel draining back into the tank over night? I always hate cranking the motor over and over untill I can suck up enough fuel to fill the lines.

unless the carb is leaking there should be enough fuel in the float bowl to start the car and run for a minute or two.

The mechanical pump has a one-way valve built in, it should prevent drain back. A little debris under the valve and it don't work. Cleaning mine made a world of diff.
And like Mark said, should be enough fuel in carb bowl unless it has sat for a while.

I'm not saying that that is not a possibility.

My original question was a bit mis-leading. Instead of saying overnight, I should have said - after about 2 weeks. I rarely start her on a daily basis but when I do, I don't have to crank and crank. Only after a week or so.

Sorry. Still, totally could be a leaky carb or sub par fuel pump.

If it is a leaky carb you will most likely smell the raw gas, especially if the car is in a garage. And that has to be fixed for obvious safety reasons.

I have had two single carb cars that had this same problem (most recently, a 124 sedan). Never was able to solve the issue and tried all the known "fixes". Just put an electric pump on it, and it will start instantly, even after weeks of sitting. Not worth wearing our a starter, IMHO.

I have thought about doing this but so many people who switch have so many problems. Doesn't the pump have to be mounted in a certain place at a certain angle?

Also, It would be stupid not to remove the pump cam and cut the lobe at that point and have a compleetly interference free motor - how hard is that to do?

the stock ele pump is just infront of the driver side rear tire "were all cars have a fuel line"
look up more progress by azgoustoyou"brady"he went over this with somebody
