Another Zenith problem

Allenk-

Hopefully others will correct me if this is wrong, but I think if you use a pressure regulator like Holley it allows for a line in, one to carbs and one to return line. 3 ports on the reg.
You might check the following post, it has good info on using a loop setup. (hope this link works)


Webers and fuel pressure regulators, yes or no?

Actually the Holley regulator will work with a return but was not designed that way. The extra port is to either feed both bowls of a Holley 4bbl or to feed two carbs. Either way I'd make sure the return is smaller than the feed or at least has a restriction to keep from starving the carbs. A return style Barry Grant regulator would be better but they're pricey.

Yeah, I was thinking, there must be a way to "T" the fuel line and then add a pressure releif type valve to the return line so it opens at the set pressure. I'm going tp look into that.
