Fuel Pump Wiring Grommets

WickedSnake00 · October 11th, 2011, 09:57 PM

Since the dual FPDM wiring requires a second set of wires to the pumps, I have to figure out how to effectively seal the wiring for the secondary pump to prevent throwing EVAP codes.

I picked up a container of assorted grommets from Advance and I'm contemplating 2 options; two holes and grommets or running both of them through the same grommet/hole. Space to drill on the hat looks to be at a premium so I'm leaning towards the single hole option.

Has anyone done this before?

Or does everyone just say "to hell with it, delete EVAP in the tune"?

becarefull which gromet you use. it would suck to have it rot from the gas fumes.

They appear to be some sort of vinyl.

Looking at the Fore hat it looks like they just run them all through one port. Not sure how that is for EVAP though, or if guys running that hat even care much.

EDIT:
Fuck it. Here's the solution I'm running with for anyone that goes down this route:

Explicitly fuel compatible epoxy for $5. That'll work.

Also for anyone interested, I'll be using a alternator harness extension from NAPA as a quick disconnect between the fuel tank hat and the chassis harness.

i ran new 10ga wires from both my fpdm's to fuel pumps. i drilled holes just large enough for thegromet and wires to pass thru, and sealed them with epoxy inside. the top of the hat isnt really going to see much fuel except when its pretty full and sloshing around. even then, its going to be limited because of all the other stuff in the way.
