I ordered a mallory furl regulator from summit and got it in the mail yesterday. I took it out of the box and started to look at it, and I ordered the on that the tech articals told me to, but what do all the ports on the outside go to? There is four of them around it, and one at the bottom. I couldn't quite understand what the artical was telling me. If you could tell me in terms that i will understand , I would be thankfull. I have a 1990 TBI and I'm putting in a holly 750 carb

 

The port on the bottom labeled "bypass" is for the return line. The four ports are just for flexability. Run a line from the tank to one, and run one to the carb. Then plug the other two.

 

Thanks, that is what i thought, but I was not sure. What should I plug the holes with (the cheapest way?) Also can I put A fuel pressure gauge in one of those holes?

 

You can get plugs where you get the fittings for it, and yes, you can put a gauge in, you just need an adapter.

 

got my hardware at napa....paid $7 for a gauge install it between the carb and regulator...5-7 works best for me
