Need help with after market fuel gauge

[Bumpside70]

Has anyone in here installed an aftermarket fuel gauge in their truck? Is it difficult or straight forward to do? Thanks for your help

Straight forward... You need to measure the resistance through the float when full and empty before buying the gauge. Don't trust what any application guide says, test it and note the resistance when full and empty to make sure you get a compatable gauge and then remember what it reads when empty so you don't get stranded.
