FPDM Question

[maxwell6]

I have a question regarding FPDM install. Pardon me if it is a stupid one but here it goes, when does the 2nd pump run,when wired directly to the pump from the slave FPDM, does that pump run the same time as the master pump. Thanks for any clarification on this.

If wired correctly, both run.

Thanks ZR thats what I wanted to know.

Not quite, depending on the year, there can be 2 fuel pump delivery modules under PCM control & the second pump is turned on based on load

This is on a 2002 gt with a 03 cobra tank and hat.

Not sure on a Shelby but the Cobra runs both pumps all the time.
