cafoose 3,360 #1 Posted September 4, 2018 I just got an electric fuel pump for my 520-HC off eBay and didn't get ant instructions for the wiring. Which is positive and which is negative? One wire is all black and the other is blue with a white stripe. https://www.ebay.com/itm/141845126993 1 1 Share this post Link to post Share on other sites

Racinbob 11,398 #4 Posted September 5, 2018 I've got two of the same pump still in the boxes. The wires are red and black with the red on the same terminal as the blue and white on yours. 1 Share this post Link to post Share on other sites
