Access to the bolts holding the tank seems good. I’m a little worried about how hard it will be to wiggle the tank past the hard lines that run to the sender without damaging anything?

Also a little worried about the filler neck grommet. How does this get removed?

He ordered a tank made by Spectra (GM49B) for 1972 with EEC has anyone used this tank before? If so did you have any issues getting everything to line up?

Pretty easy to do. Need to change all the hoses including the ones under the truck.. I also have a 72 C10 and have all hoses as original design including a new vapor canister. There's a hose from the tank to a hard line under the cab. If original there are two hard lines along the frame. They break under the passenger side and have short pieces of fuel hose between and take off from there. Change them, also. I've had them leak twice. So much easier with no fuel in the line. Don't scrimp on the hose quality and maybe use fuel injector hose. You'll be OK with the hard lines in the cab. They go through the rubber grommet in the floor and you've got enough wiggle to get the tank in. I don't know about your tank, but some of the aftermarkets' filler necks are one inch longer than a stock tank. Probably stamped at the same factory and the sellers just put their name on it. Sticks out a little more.
