PO of the 93 had installed a new lift pump and a facet cube pump, installed b4 FSV to help fix his no start, to no avail, it needed pump, we purchased it that way and did pump, injectors and gp's. Would like to eliminate lift pump and small facet with new Carrier pump, both at least 3 years old and had been setting . Runs very good now 12-14 mpg around town first 2-3 tanks, but feel we are on borrowed time. BTW this system does work well,(luck) despite all old hose's before filter head, after new pump,injectors, and gp we got it to start after about 10-12 tries, forgetting to hook up glow plug controller!
