Eric tests every carb on his own or a friend's engine. Any problems or questions, you can call him. He has even helped people with carbs not built by him when they couldn't get any help from where it was purchased. The more info you can give Eric on your combo, the better he can build to fit your needs. No detail is too small. No one is 100% infallible. It's how you take care of your customers that counts.
So that is 5/8" to the carb. What do you have for the return ? #8 is 1/2" and #10 is 3/4" in stainless braided hose. What type of fuel line do you use that is 5/8" ?
I am running one of Tri-shields mechanical fuel pumps with a 1/2 line from the tank and no return, been doing it for 5 plus years no issues.
It's #10. I don't run a return style regulator. The pump has a built in return at 12psi and I run 6.5psi to each carb bowl via 4 port reg Cheers
I runs s 1/2 line from the tank with a Tri-Shield mechanical fuel pump with no return for over 5 years and no problems. Just for reference my engine makes 600 plus HP.
Actually #10 is 5/8" ID. A #12 would be 3/4" Hose Sizes: -4AN (1/4"), -6AN (3/8"), -8AN (1/2"), -10AN (5/8"), and -12AN (3/4").
I'm up and running may try to open it up tomorrow on the way back from alignment, Friday and Sat its getn a workout for sure
