think I could make a purge kit out of....

some fuel solenoid form a wet kit?

I got a used kit, and wanting to run a new fuel solenoid, and 2 nitrous solenoids in a row(one new, one old for safety)

With the old fuel solenoid think it could work as a purge kit?

doubt it, a nitrous solenoid might work. who knows if the fuel noid would hold back over 20 times the pressure it normally sees

I am pretty sure you have to use a Nitrous Solenoid.

fuel solenoid won't hold up to 1000 psi. wasn't made to.

serene - a nitrous solenoid and purge are the same type of solenoid.

yes a fuel solenoid will work,but the seals inside arent meant to deal with nitrous.
