Which jets? And stock fuel pump Q

Which jets do you guys run in your webers?

I have a 34degc (or what ever the code is), and i have a 47.5, and a 50(or 55 - can't remember) and I'm just wondering if I'm using the right jets, or should I be running a different size jet?


For our stock mechanical fuel pump, after the pump I have a holley regulator on it, set at 3.0psi right now, and I was wondering, I'm going to be putting a fuel cell in, and I'm going to be blocking off the return line on the fuel cell, will it be alright to plug the return from the fuel pump without having to worry about pressure build up in the pump?

I figure it would be alright seeing as how our pumps aren't high pressured or anything. This will only be temporarily until I get more money to buy an electric pump.

Thanks guys

here's a link that shows what the base jetting the webers are coming with.


as far as the stock pump, i wouldn't block off the return, it is there to equalize pressure in the tank, not likely to happen, but if the vent got stopped up somehow, it could collapse the tank, you might even cause a vapor lock situation & those are agrivating as heck....I'd just save a few extra $$ and put the fuel cell & pump in at the same time.

Redline has a 1-800 tech support number that u can call,give them ur application and any mods u have and they will tell u how to set the carb up and what jets to use.BJ
