MEP-802a / 803a fuel pump connectors

[Digger556]

One of my units is missing the connectors for the main fuel pump, both on the pump and harness side. I have tracked down the part numbers for the pump side housing and pins, and the housing for for the harness side, but I'm struggling to identify the correct P/N for the harness side pins.

Any help would be appreciated.

If you don't want to go through all that, just make some jumper cables with M/F insulated terminals and get it working for under $1.

and if you are dead set on replacing it with the same connector, it's just a molex 2 pin(I forgot the pin diameter). You should be able to find them at a real electronics store, or online as long as you know the pin diameter.

Most times the old hard copy Molex catalogs would tell you the mating pin series# on the same page as the connector / pins that you located.
Maybe they show the same info on-line if you look up the Series / PN of the half you located?
But I would also just go with M/F .250" Fast-On connectors like L.I.T.D suggested.

Unfortunately I dont even like these Molex connectors, but I wanted to return this unit to a OEM condition, giving me the abilty to swap pumps easily if necessary.

From the TMs, it is easy to track down the housing numbers, but the pins are proving to be more trouble. Worse, the datasheet for the housings lists several pin series and it is going to take some leg work to figure out which one was spec'd for the MEPs.

Thanks Guyfang for helping me understand how to read the harness diagrams, I'm glad I ordered the right housings. Here is the parts I ordered:

Fuel pump connector housing:
Molex 03-09-2022

Harness connector housing
Molex 03-09-1022

The pins were the hardest part to figure out. I ended up ordering spares from Green Mountain under the TM P/N and measuring to determine the Molex series

The fuel pump pins are male, series 1190. I used Molex 02-09-2101 part number (tin plated brass)

The harness pins are female, series 1189. I used Molex 02-09-1102 part number (tin plated brass)
