dual tank switch difference

[kglowacky]

running two tanks on my 78 c-10 does anyone know the difference between the 78 tank dash switch and the 88 tank dash switch, They want double the price for the 78 one. is it in the way it mounts and connects or just visually different? Thanks

Different switches altogether. http://67-72chevytrucks.com/vboard/s...d.php?t=754061

I used this one on my 75: https://www.oreillyauto.com/detail/b...k+switch&pos=0

here's why I am asking. I am running two tanks on my ls1 swap and I am running two sending units and two pumps One in each tank. I a going to control the tank(pump) usage by running the power for the pumps through a switch I install in the cab. Going to duplicate this for the gauge. My question is can I use the newer switch as I need to buy two and will it handle the 12 volt from the battery. Going to use relays on both switches at this point not sure if I need it on the senders.
