'70 Charger - Thoughts on installing Fuel Line Check Valve to help reducing starting turns

[matchek]

Hi gents, been awhile. Car needs excessive starting turns when sitting for more than a couple of days especially in the winter months. It's been cold this year too. Summer not as bad where it may be affected after sitting more than a week or two. I saw this Youtube video where someone installed a Carter check valve on an old Pontiac to reduce the amount of fuel that returns to the fuel tank. I have Amazon link below of the part. I was wondering your thoughts on this pros and cons. I have a 67 442 that needs extra turning too but not as much as the Charger. Seems like my Charger system need many extra turns in the not warm/cold months where gets annoying and just thinking of ways to making it easier.

If I didn't want to add a check valve is there anything I can spray in the carb to give it boost? Pour fuel in all in the 4 jets? Thoughts appreciated.

Check valve will do nothing for your situation. You could fill the bowls before starting. You also could install an inline electric pump that you manually activate to prime the carb when starting.

No specs from Amazon, what a surprise. Looks like 1/4" pipe thread. If your fuel bowl vents correctly, it shouldn't siphon back to the tank. Fuel pumps have their own valves, so if the pump isn't the issue, it may just be the 10% ethanol in the gas nowadays, unless you don't have that in NC.

What sort of fuel system do you have that has a return?

The fuel is evaporating from the carb bowls not draining back into the tank.

I made this thread a sticky for easy access. Electric priming pump for fuel evaporation issues.

Are you certain your choke is set correctly and not hanging open on a cold start?
