Non return valve


Davo

Recommended Posts

I have a typical problem of when I start the pinto engine after a couple of days, it takes a while to get the fuel flowing. My guess is because the fuel seeps back down the pipe. It's a mechanical engine driven pump. 

I was wondering if a non return value would help this?

If so, where to fit?

Near the carb to keep it primed?

Just before the pump in case that's got the imperfection?

Back near the fuel tank to keep everything ahead of it primed?

If you are still using the mechanical pump then drain back is normally a sign of the one way valves/diaphragm thingy is on the way out. Fitting a one-way valve will help but probably need a longer solution or retrofit an electrical facet pump.

Thank you, so you would suggest then it would be best to fit just before the mechanical pump?
