Does anyone have a wiring diagram for wiring in twin walbro pumps, running second pump with a hobbs switch???
Plenty of info here for plumbing the pumps not much wiring info to be had.

 

Ive been wanting to do the exact dame thing. I know racetronix makes a hotwire kit, i take it you would need two? Also, can you use the factory connector on the sender (the larger 30 amp one for an 05 model returnless), or do you need an additional connector to feed the wires to the second pump?

 

use two hotwire kits.

use hobbs to trigger hotwire kit #2 relay. whats difficult about this?
