hi guys, Yesterday I rewire my walbro with a 30amp relay using 12ga wire.
The pump it's working excellent and the car feels awesome but i'm having a issue with the relay getting excessive hot. All is new and the wires are crimped and then solder.

This can be a Ground issue? I just put the ground to the seatbelt bolt just clean the area not grinding or sanded.

 

Do both the ga wire match?

 

I don't understand!!

You mean if all the wires are the same size?

If is this then YES all the wiring it's 12wga.

 

Could be a bad wire. Or old wire

 

Could be bad wire or old wire bro

 

All is new and the wires are crimped and then solder.

 

Idk man u may want to try to file down a lil where u grounded it just to get bare metal showing. Not saying this is ur fix but it's possible it will at least help.

 

Lol did you change the battery?

 

Why did you change to a 30A main relay? Why are you using an aftermarket fuel pump?

 

I'm running a ls vtec turbo @ 17psi/ 393whp 279tq. and I was having problems with the pump voltage with some accessories turned on.

And the guys from Forced Induction recommend this.

Now the problem gone, but after 15 minutes I touched the relay and it was hot more than normally.

 

Main relays get hot. That's normal.

 

thanks!!! I go to use it tomorrow to work and see how it behaves.
