Default Freaking%&# vapor lock 312 Fasteech

97 312 Fastech 454 mag mpi.. I have the VST's Took her out this weekend and both were Vapor locking, One would restart and runs about 155 on the temp the other runs 165 and I would have to wait until she cooled to get it started. Seawater pumps I just rebuilt and seem good...Only when it shut off.. It runs like a champ unless I shut her down.
Even if I leave the blower running..
I know there are lots of posts on the Tech site but I want to know what Formula guys do... This just sucks.
How cool can I run MPI's can I run 140 deg thermostats.. Do I need to change the elec fuel pump in the VST to the higher pressure one? HELP....
