Ultimatly a $60 precaution such as this can save me some agrivation.

Can you give me any advise on the wiring & instal.
-What triggers the solenoid ? ( same MAP sensor wire ?).
- is it positioned on the high pressure side (just before the nozzle) or between tank & pump.

This valve answers my question in previous post (will some mechanical one way valves open due to suction). This one looks like an easy install and less complicated. Reasonable in price as well.

It still surprises me that any vendor would sell or design a methanol system without a check valve or strongly advise to install one. It's costing me around $12k because I didn't have one as well as another in OK who didn't have one either.

Mine is installed right after the pump . 2 wire hook up. Ground, then hot wire hooked up to pump hot. Solenoid is triggered with pump.

My Nova would siphon mine just slightly. Probably a quart every few hundred miles. Seeing as how the intake ports, valves, and pistons were almost spotless, I let it go haha.

I just ordered a check valve from Alky Control. Inexpensive & simple to mount.

After dropping my reservoir a few inches, effectively making the nozzle higher than the fluid level, my siphoning issue went away. Driveabilty improved & the stumble in the lower RPM range went away. The check valve has a 10# pressure prerequisite. That should do the trick & then I can retire my new ZIP TIE bracket system for the reservoir.

Thanks for everybody's help !!
