Question Electrical fuel pump relay?

I've heard that if you pull more than 15amps that you should mount the relay as close to the item in which you want to power up. That beings said is it best to mount the fuel pump relay in the trunk area, say the inside or on the package tray support or on the trunk latch support? I've thought about putting a junction block in the trunk area to power up other items as well as placing ing. on block to trip the relays for all items that power up on key on. that being said should I run a independent power wire to my pump or will a junction block support say a 30 to 40 amp draw with out a glitch? Any and all suggestions would be helpful thanks. I am going to get the Mad kit for the lights and front end but want to build my own pump run.

Re: Electrical fuel pump relay?

mad also sells a general purpose relay kit, #RLY-1 which would do nicely.

If your battery is in the trunk and you have a junction block there, you could put the relay there and run a single ingition switched wire back there to turn it on, or put the relay up front, no real difference.

If your battery is up front, it will be easier to put the relay up front and run a single wire from the relay to the pump. The ignition lead is all ready there.

Regardless, I'd use 12 guage wire (power lead to relay and lead from relay to pump) and a 20 amp fuse.

Re: Electrical fuel pump relay?

As Jim said , the relay needs to go closest to battery. I put my fuel pump outside the car ( no fuel leak fire hazards and noise) above the leaf springs in the right rear corner at about the same height of the fuel tank.
