Unfortunately Rodknock purchased a valve intended for Chevy's with a single external pump.
What he needed to buy was the much more expensive FV 11 which will switch power, sender, supply and return for two separate tank
modules in a Ford Hot Fuel Handling system.
What engine option do you have in your '86 150 Royce?
Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.
