Hey pitts racer , you ever blow thru the check valves to compare them ? Ive only messed with 3 ,but the one I have on my barracuda is the easiest opening of the 3 , was a fair amount of diff. between them !!
No I haven’t. I just order them from Summit and throw them on. I’ve found with alcohol I had to step up my maintenance program and switch them out every few years.
