Nitrous fuel supply question
Installing a Nitrous Express 50-300 wet kit. It's going to require 10 psi fuel system. Going in 83 rx7. Installing 2 foggers direct injection into intake. 50 hp shot. Need advice on supplying fuel to the system.
option 1: Install single larger fuel pump. Split the output. One side to carb with regulator. Other side to nitrous system with a return line to tank.
option 2: install second dead head fuel pump for nitrous system and have it come on with the arming switch.
Not sure which route to go....

How important is it that the fuel feed to the nitrous path be instantaneous? It seems like a second fuel pump would take time to spool up but that the unregulated side of a single pump would already be there. I've never done this so take an experienced person's opinion over mine!

Two pumps means there's a big chance it might freeze up, unless you run it regularly to keep the pump clean. Also old fuel in the feed lines could be a problem. You'd need to verify it's on and working before hitting the nitrous. Larger pump with a split output seems much easier and more reliable, less parts in the system is always a plus.
