I am taking Alex's advice and using my drain plug as a secondary fuel pickup. I will be running 2 Holley blue pumps, one for the carb & one for the nitrous. My question is, should I just run the line from the drain to the nitrous pump, or should I combine the drain & the regular line, and then split them off to the 2 fuel pumps? Thanks!

Do you think the drain plug opening will be large enough to flow plenty of fuel for the n2o?

Yeah, it will be loud. But it will be wired so that the 2nd pump is only on when the nitrous is armed. The nitrous will only be armed at the starting line, when I have the open headers!

100 to 150 shot. I'll double check the size of the hole.

Alex is right.. The drain is a great way to run a second fuel system. I run a Blue pump with regulator for my carb out of the stock pick-up location. I modified the stock pick-up by putting in 1/2" line. For the nitous side I'm running a Red pump.If you run a Blue pump on the nitrous/drain side you will have too much fuel pressure, because the pump will deadhead at the fuel selenoid.I tried it this way. If you use a Red pump you will get about 5psi at the selenoid.I tried running the Red punp with a regulator to be able to adjust the pressure and that caused problems.Since I removed the regulator it works great!! Save your $$$ and by the Red pump...

Well, I already have a 2nd blue. So I figured I would just regulate that one down to 6 or 7 psi for the nitrous. Would that cause a problem?

Regulate the pressure by check flow.What i mean is you want to check the pressure as if it is flowing with solenoid open and spraying through spray bar.I have an extra plate so i put in the jet im going to use then put the plate in a bucket and activate the solenoid.Then check to see what the pressure is and adjust it from there.6-7 static psi depending on jet size may only be 4psi when spraying and thats not good.You want 5.5psi when solenoid is open and gas is flowing through spray bars and jet.
