Default Quick dual intank walbro question

Can I run both off the stock wiring, or would it be best to run both off of dedicated relays?

Run them both on their separate relays triggered by the stock wire (yellow/green)

This is going on a e85 setup, what micron filters should I use? Any brand recomendations?

Just a thought, wouldnt it be better to run the trigger for both the relays together so that if something goes out both pumps will quick working? That way it doesnt lean out. We have a fullblown dual in tank in a car at work I installed and was just wondering if this was right?

I have mine on one 75amp relay with a 8ga power wire feeding it that way if the relay goes it will not run on one pump.

Sounds good, how did you run the wires on that setup...?
pin 85 will be 12v trigger
pin 86 grounded to body
pin 30 battery input wire the battery is
pin 87 will go out to the + terminals on each pump


So what the word guys? One or two relays?

Fuel lab makes a 6 micron fuel filter that is compatible with e85, and gasoline. The walbro filter sock is 30 micron. So you will want to use a smaller micron filter then 30 microns.

The one i used is a big relay it is not # like that. It has a big screw lug for power in and out. and two small lugs for the switch power and the ground. on the power out to the pumps i run 2 10ga wires and bolted them to the relay.
