Rear fuel pump bulkhead
I know this a shot in the dark but does anybody know if there is a source for those fuel pump bulkheads behind the rear seats?? Mine is shot, I get power thru the grey wire to that bulkhead inside the car but nothing goes to the other side above the diff.
I've searched the internet everywhere and come up with zip. Maybe I'll just drill a hole put a grommet in there and pass some wires thru it and put a female connector on it and be done with it.
Anybody else have issues with that thing after their car has sat around for a few years, like 5 in my case?? Thanks everybody

Re: Rear fuel pump bulkhead
It actually shows as "on backorder" at Mouser last time I looked. It doesn't show as obsolete, so you might be able to get one. I was going to order one and see what happened

The Third-Gen Part never went OBSOLETE the way that more recent Part Numbers have...
They just stopped production of them.
I do find them NOS, on very rare occasions (almost always under an incorrect Part Number... the original Part Number is inactive).

Scooter, that Delphi Part Number is for the 4th-Gen F-Body pass-through/ bulk-head electrical connector (and yes, you are correct... this part number is still ACTIVE).

Re: Rear fuel pump bulkhead
About the only thing you could do at this point because the bulkhead isn't serviceable is to open up the housing, resin it to a female weatherpak and plate and seam seal the area. I hollowed out mine originally to run larger gauge wire for a bigger intank. Its a stupid setup.

So Any of you guys that are looking to run a Big High-Amperage Pump should not use the Bulk-Head, or...
Remove the Ground Circuit from the Connector... ground the Pump to a location outside.
Then run 2 12v+ Wires through the Connector.
Now you have a total of 40A Continuous Load through the Bulk-Head.

Re: Rear fuel pump bulkhead
The Weather-Pack Connector is ONLY rated for a 20A Continuous Load per Terminal.

Re: Rear fuel pump bulkhead
The very common Deutsch (DT) Connectors are only rated at 13A per terminal.
Weather-Pack = 20A.
Metri-Pack 280 = 30A.
The smallest Deutsch (DTM) Connectors are only rated at 7A per terminal.
There is a larger, less known Deutsch DTP Connector...
But only comes in a 2-Way or 4-Way Connector = 25A.

Re: Rear fuel pump bulkhead
I wouldn't run the stock wiring an connector anyway with anything but stock pumps. The intank as well as the in car wires are lucky to be 14-16. A 315lph will pull 14-16 Amps, but you loose voltage on the length by way of voltage drop if you use the factory wiring in car which is 14 most likley 16g.You can get a upgraded intank wiring from racetronix. Factory wiring in tank is like 16-18g.On the bulkheads you can run a Deutsch connector which is rated higher. Just need the correct tools to crimp, plus fab your own seal. Maybe a 400lph or dual will pull more than 20amps, but you can buy gm metripacks with the upgraded pins for 12g wiring. 315lph will fuel 99% of the cars on this board

Re: Rear fuel pump bulkhead
The Molex MX150 Sealed Electrical Connector Series is a quite nice, relatively modern System of Connectors.
Like many Connector Systems with a 1.5mm Terminal... the design is based off of the Delphi 1.5mm Metri-Pack 150 System.
The Molex MX150 offers one of the highest Ampacity-Ratings available for a 1.5mm Terminal based Connector Series.
They are rated for 22A per Terminal.
Most Connector Systems that use a 1.5mm Terminal, max-out near 15A per Terminal.

Re: Rear fuel pump bulkhead
Hey, this 4th gen ABS fuel pump pass thru looks interesting with mixed Metri-Pack 150 / 280. Does it have serviceable terminals, or is it like the 3rd gen C313 where it cannot be modified?
There is like almost zero info about these things on Google.

Re: Rear fuel pump bulkhead
(who knows with Aftermarket replacements).
That Bulk-Head came in about 8 different Variants with different Terminals Populated (depending on the Vehicle and use of ABS/ Rear Suspension Position Sensors.
All I cared about was the MP280 Terminals...
Often I would be able to get a Variant with 7 of 8 Terminals Populated.
Should be Part:
-GM= #15305930
-ACDELCO= #PT1070.
