How to prevent siphoning alky from tank..?

[MattSwindle]

on my F-body the top of the pump is even with the top of the tank..with the
bottom of the tank being 4" s below the bottom of the pump..
the dual nozzles are 11" s above the pump...
I can only drive about 12-15 miles before running out of alky..
so it's siphoning as I drive..
what's the solution..? adding a solenoid?
if so..how do I tie it in electrically..?

Thanks Ahead!
Matt

by the way..car ran a 10.67 @ 127 on the brakes..
with only a 1.53 60' ...

hope to get to 25 degs @ 10.5 AFR..

Hey Matt,
Stop drinking the alky! You've probably got a siphon hose inside your car for when you get thirsty.
