Jumper to avoid being stranded with a failed Primary Fuel Pump

Count me in for two sets.

I am going with what Jim described as follows.......and I am assuming 90's and 91's are identical.



Black is Black,
Purple I call Red,
Gray I call White,
Green/white I call Green.

Four Jumpers for Dynomite.......

Not what I meant but I'm pretty confident that what I mentioned in my post is correct A - black 12:00 to latch and the D - green/white 3:00 to latch. That would have confirmed my shell part #'s.

For the length of the jumper, I recommend 8 to 12 inches. That length allows the harness to be pushed below the rubber boot one "lump" at a time. Then the wire can be pushed in. If the jumper is too short, the whole rigid part becomes bigger than the opening.

All that said, there is plenty of room below the rubber boot for the connectors and wiring.

On a different subject, I recommend that if you use the jumper to swap a failed primary fuel pump, you should turn the Power Key OFF. Without the second fuel pump operating, if the secondaries opened, there might be a problem with a lean condition due to insufficient fuel supply.

12020832 looks to be indexed A @ 12:00 (black) and D @ 3:00 (green/white) with the latch on top, this is what is currently on the sender with female terminals in it. Several vendors have that shell. 12020830 should be an appropriate shell for mating and would require just the appropriate male terminals. I don't know why you would need the CPA but 12020833 would get you that if you wanted a couple.

15324982 should be the correct green seals for the individual wires in the connectors.

I'll post back with what I believe should be the appropriate terminals. I don't recall the wire sizes and I'll need Jim to verify the indexing of the shell on the tank unit. I'm doing that mostly from memory but I believe it's appropriate.

Mouser it appears seems to have the correct shells and the CPA. Just use the part numbers I mentioned above to search. They could be available from many others and I don't buy often from Mouser but I've had good service in the past. Their "minimum" best I recall was very realistic and if someone was doing a few of these it would likely be appropriate to just let that person do the procuring from whomever. I didn't check the vendor I use for these part numbers.

12089040 for male terminals I believe (I assumed .5 - .8 wire) and 12089188 for the female terminal.

Part #'s required per car:

12020832 X 1, 12020830 X 1, 15324982 X 8, 12089040 X 4, 12089188 X 4 and 12020833 X 1 if you wanted the CPA.

Yes, the tank unit connector is indexed A @ 12:00 and D at 3:00 with the latch up.

1. GOLDCYLON (Sending to Jim Voter FREE)
2. PHILLIPSLT5 (will be paid in person with a cold one in hand)
3. GEEZER (Canada) (Paid)
4. ZR1North (Paid)
5. GSJOE X 2 (Paid)
6. CHRISKINZEL (Awaiitng Payment)
7. CVETTE98PACECAR X2 (Awaiting Payment)
8. DYNOMITE X4 (Paid)
9. NELSON007 X2
10. WEGONE (Pending Payment/Check)
11. SCOTTZ95ZR-1 x2
12. MYSTICZR-1

OK count is at 19 we will make a round of 20 for lot 1

Guy said he will do a long custom measurement with end to end wiring. It will be heat shrinked or wire wrapped to prevent chaffing. Once I have the proto type in hand I will post up the pics and the ordering instructions. Sound good? GC

Sign me up for one.
Hope I never need it...

[ScottZ95ZR1]

I'm in for 2 also

If there is an option to buy surplus backshells and pins, I would be interested for that as I can (and would prefer) to make my own wiring to keep it cheap.

Ok 17 and the parts have been ordered
