They do, it is a real small hose close to the front of the head though. Hard to plumb a gauge into the 12 valve to measure pressure, unless you go to intake side rear of the head.
Ok, I thought it might have been adjustable. What pressure is it set at if you don't mind sharing. I will be calling you tomorrow for some prices on a few things, poss package deal. By the way, this dragonslayer pump rocks.
These would definitely benefit a high RPM 12 valve motor. I blew one on my pulling truck. I already bought the kit from EEP or else I would be looking at buying one of these. Nice looking kit.
