[QUOTE="MalcolmV8, post: 13637565, member: 8854"] You keep the FPDM to trigger the relay that turns the pumps on and off maintaining OEM type operation. If you remove the FPDM then you wire the relays to key on power and anytime the key is on you have the fuel pumps going full blast doing nothing but draining your battery. This thread has details on the wire up [url]http://www.svtperformance.com/forums/engine-tuning-214/824371-return-style-wiring-how-allowing-oe-type-fuel-pump-actuation.html[/url] And no this does not affect fuel pump flow or anything like that. The FPDM will not be controlling the duty cycle (speed) of the pumps like it was in the past. Its simply turning on the relay that sends your pumps to 100% power when they are needed. [/QUOTE]
