Great post OP.

So you can run two pumps off the harnerss above without anything else??

 

this might be a dumb question, but whats the need for evap? isnt that like the first things you get rid of in your tune??

 

No that's EGR (exhaust gas recirculation). The point of evap is to capture evaporated fuel and route it to the combustion process to be burned off. Then the excess exhaust fumes/vapors are routed into a charcoal canister on top the gas tank to help with keeping the smell down.

 

This ^

 

Thanks for the nice words. I'm not sure what you mean by your question. You would still need to run relays and fuses like my schematic shows or use a racetronix harness. I would suggest that you buy the fuel pump connectors to properly hook up the pumps inside the tank rather than using butt connectors and the walbro harness.

 

Is this harness capable for 2002 Camaro?

 

well IDK about you, but I been running a single plane setup for a while and sure dont have any connection for EVAP

 

That's fine.. my evap line is disconnected from the intake as well. I just ran a small filter up on top of the gas tank on the evap outlet line. The charcoal canister is still there as well.

 

I noticed you are using the factory inlet plus adapter for the return, what is the other line for with the factory hose?
What -AN fitting is the send?

 

The other fitting is for the evap system.

 

Great write up.

In for the rest of the pics. I need to see where I cut the trap door for this, and did you have any issues with the -8 bulkhead hitting the body/floor above the tank?

 

....double post

 

Instead of running two 12 guage wires from the battery could you run one 10 gauge or 8 gauge wire? What would be needed to power both walbro pumps off one wire from battery?

I wanted to make it as simple as possible and run one power wire back to the relays.

 

I didnt have any problems, but i think it was because i had dynamat on the floor on the car. It provided the needed clearance since i made an access panel that was bolted on top of the trunk floor.


Bone head move. I dont believe i took pics of the cut and cover before i put them back together.

I wouldn't run it that way, unless you fused the 8 or 10ga wire, then fused each pump again. Its too risky to run a main wire like that without fusing properly. You'll burn your car up. At that point, its just much simpler to run a fuse and wire for each pump.

 

thanks ! just saved me some money

 

i was just gona ask that

 

It keeps the fuel tank vented correctly without any stink. You can delete the codes so that your car will pass obd2 inspection without a problem, but i would still keep the equipment there.

 

nice information.

 

Nice wright up helps get a better under standing and visual of how it should be done.thanks for sharing

 

good write up!!!!!!!!!!!!! also thanks for sharing!!!!!!!!!!!!!!!!
