Thanks for asking, it's driving great ! I still shake my head in disbelief at times that this truck turned into such a nice driver.

Hi Paul, Pressure too high can cause the carburetor to flood if the pressure overcomes the force holding the needle valve down. I read a couple of install blurbs for Holleys and they aren't as adamant about pressure as Edelbrock. I read one said 5-7 psi is OK which means in that case you wouldn't need a regulator. Just read the manufacturer's recommendation and you can't go too far wrong.

About your leakers, make sure your hose IDs and tube ODs are the same size. If the metal side is out of round or corroded that could cause leaks, too. I used AviationFormAGasket on one tube/hose connection on my old setup cuz I couldn't get it to stop leaking and that worked.

Thanks. I used to dread steel tubing, but now, I got the hang of it and I really liked bending the stuff. Good tools and materials help a lot !
