Here is the Schematic I drew of my plumbing. You think it would be okay to use the fuel pumps like so? I do not want to spend money on a dedicated Nitrous tank unless I absolutely need to.



Here is the Electrical Schematic I drew up in order to make it function.
I am using a 4PSI safty fuel switch and WOT switch.

I will make my schematic for my Timing Computer and MSD-6AL later.



Any suggestions?

 

run a mallory 4309 or similar regulator with a return line for the holley blue, you don't want to deadhead these pumps for too long or they can get hot and burn up.

 

I thought this particular pumps were designed for 2 port? That is why the even come with a two port regulator?

Also, If I "Y" split the fuel supply line would two pumps "Y"ed to it be sufficient or do I have to run a whole line back to the tank?

 

since the red is only used during nitrous runs for 30 seconds or so it would not need a return regulator, unless the lines run next to a heat source and would cause vapor lock. I'm sure it's a cost savings thing for the blue to come with a 2 port deadhead considering the mallory is $75 IIRC and the holley blue and regulator is $130-ish last I remember.
