Airtex fuel pumps

[Roger/Sacramento]

I need the mechanical pump to connect the stainless fuel lines as shown. The problem is the electrical pump will cause gas to weep out of the diaphram when left on past priming the pump.The mechanical pump is sold by Amazon for$35.

No gas should leak around fuel pump diaphragm if all is well with the pump. If fuel is leaking with electric pump running then it will be sucking air when the mechanical is in use.

There is no electric pump that will self limit to the 3.5 psi limit of the carb floats. So, any electric pump used more than just momentarily/intermittently requires a pressure regulator.
