Rotary not rotaring!

Remember when I said I don't have alot of experince with carbs? Well, here goes my inexperience. Do Fuel pressure regulators in carbureted vehicles require a return hose to bleed off the excessive pressure the regulator isn't letting past?

This regulator says it has three ports, is the third used for a return or is it for another purpose, i.e. a pressure gauge?

And to repeat what Ben said again, Thanks Everyone for the advice!

We will look everyone up at the farm!
 
Ben & Crew, hay Crew do you have a real name ?

The three ports on the Holly 12-804 regulator your talking about has 1 incomming port & 2 outgoing ports. Incomming is from fuel pump. 1 outgoing will go to the carb & the second can be either pluged, or you can plumb your gauge, or you could plumb your gauge & your fuel sample hose.

I use the stock carb & there is a stock return line comming off the carb which returns fuel to the tank via a second line to the tank.

Do you guys have a Mazda workshop manal ? The raeson I ask is that number one you SHALL have one at all SCCA races. Part of the rules. Second if you had a manual there is a bunch that can be learned. Example you have a after the fact worked on carb & who knows what has been modified, may be they closed the return line haole. If ya had the manual maybe it would help with some of these thing.

Have Fun

The carb seems to have a line that has been sealed, however, there is a hose running from the front bowl to the catch tank. We have a service manual.

The carb is stock, atleast, We think so, it looks like all the pictures in the manual.
