redneck fuel system

Sooted up from being brazed maybe?

Don, if i'm thinking right, I got half inch tube, with .065 wall, giving me an id of .37. Just seems smaller than what I had in mind.

pipe is measured on the o.d.

tubing is measured on the i.d.

.375 is 3/8 or -6

thats all i used for out of the ip to the reg - then the return from the reg to the tank is -8

if it were a nos system i woulda went with -10 return to the tank but its not - my system works great

keep us posted on yours

don

ps - dont know what you mean by sooted up brazing a plug on the end of a pc of tubing does not change the i.d. its a easy way to attach braided hose to tubing coulda flared it but i dont like flares. the braze is good to 500 psi water pressure
