Gas gauge and tank issues - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have to agree on the doing it from the top part. Yes it can be done from underneath but from the top is a heckuva lot less cussing and swearing. You can see stuff and reach stuff easier and the dirt falls away from your face.
Bed bolts are cheap and fairly accessible from the bottom. If they give you any grief you can just cut em off rather than fight with them. There's only one electrical plug on the LR frame rail. Give the new ones a Never Seeze coat and you won't have to worry about it again.

Test the dash switch first if you intend to fix the dual tank functionality. GM used a pretty cheap rocker switch. If you replace it ask for the 87-91 switch rather than that momentary switch that GM used from 81-86.
