Cjm twin fuel pump wiring
 

Hey guys Iam back , need some assistance on wiring up my twin walbro 450 to the bottom of the hat, has anyone stacked the red/ black for both pumps together in the existing spot for a single pump.?.? Any help is much appreciated not a electrical guy just good with the mechanical side of things.

The positives (Red Wires)have to been on separate wires/pins to be able to control the pumps individually. The grounds (Black Wires) can use the same pin. I used the top hat for the grounds but the problem is you have to scrap off the anodiziing to be able to get a good ground. Hire somebody if you have no clue.

The last 2 batches of the CJM twin pump have a hole next to the 6-pin connector that is plugged off with a gold anodized aluminum crush washer and stainless screw. This hole is there to accommodate a Radium bulkhead stud (https://www.radiumauto.com/Electrica...ack-P1049.aspx) for the sake of adding a 7th wire position. This is to allow for 4 pump wires and 3 sensor wires.

Since the radium studs are sold in a 6 pack, CJM is stocking them and selling them in singles. This change has not been reflected on the website as it will be added along with a handful of other updates all at once for that product page.

Cool deal. Getting a good ground was a pain in the butt when I installed my surge tank. I got it right the 2nd try.
