nor will the engine. at 18psi on mfi you're likely to melt something sooner rather than later. i wouldn't go more than 15psi on mfi to be honest. as said convert it to a modern system of some description. it'll be more reliable, cost less in the long run and drive so much nicer mate. plus it'll actually start first thing in the morning.
