Kinda crummy picture , but i sumped the tank in the Luv and went with aluminum tubing and compression type fittings to 2 old style fram can style filters to 2 Holley blue pumps to 2 Holley cheapy regulators . i used the factory steel line as the return back to the tank . The trick to get the cheap Holley ones not to creep is to restrict the returns with a carb jet . That's right , come off the return line with a brass fitting , tap the fitting to fit the smallest carb jet you got , take the jet and heat it with a propane torch and fill it with solder , take a small .015 index bit and drill through the solder . Now the regulator is not dead headed and won't creep , but you have no pressure loss from the return . i had the nitrous guy use his big 1-8 # gauge and flow everything . Never had a problem . Sprayed 250 this way . I have been told that a single blue pump is good for 500hp , N/A or N/A + N2O .
