carbs and Nitrous

Your fuel pump and lines should flow .10 gallons per hour per HP at 5psi.
For example, a 300hp engine should be able to flow 30gallons of fuel at 5psi. This is what the NOS instructions say for the sniper system.
If you still have a stock pump, I would at least get a high flow fuel pump or go electric.

I installed a Mallory 140 electric pump, that fed a high performance Edelbrock mechanical pump on my 65 Coupe, daily driver. I then fed the line to a regulator with a 1/8 NPT to install the fuel pressure gauge. One side of the regulator went to the carb, one side to the fuel solenoid. Set pressure at 6 pounds. Also had a Hobbs switch in line that was set at 5 pounds at the N2O side. If pressure dropped below 5 pounds, the sytem shut off.
