Has anyone came across a fuel leak at the mechanical lift pump coming out of the pump where you seem to not be able to get the fuel to stop leaking? Like the flare wont stop leaking. I tried replacing the mechanical lift pump and the line going up to the carb and it still seems to leak. Is there an electric fuel pump conversion for this or just buy the block off plate or make one and put an electric pump on it and be done with it.

 

Maybe a little teflon tape on the fittings.

 

I have never seen one leak there? You have a metal line into a pump and you have replaced both the line and pump and it still leaks at the same spot?

The only thing that makes sense to me is at some point the threads got damaged, Installing the damaged line into the new pump damaged the new pump so then you installed new line the pump was already damaged.

Back in the day I saw newer mechanic struggle to get metal lines to go in straight. There is a feel for it and they must go in straight. Other then that those connections are pretty built proof.

Yes all the parts exits to convert your car to an electric pump. It is a common upgrade when building a high HP car. It will be pricey. you just need a pump and regulator and a return line.

 

The metal flare has a crack?
Tightened too tight?

 

Its a flared end on the tube and into the pump. It wasnt overtightened at all. Im not sure if teflon tape would help, not sure if it would make the leak worse by not having the barb in all the way. Just my opinion.

 

What would the fuel pressure need to be set at?
