Ok a few more questions, the fuel gauge problem is one of them. I need to get a fuel pump and sending unit from a 97 Tahoe?

Also what about a flywheel? From what I understand the 01 5.3 one will work, right? (the engine is a DBC '01 5.3 w/ 34k)

I have one financial obligation in the way right now but within 2 months I'll be actually doing the swap. Now I'm just trying to get lined out, on what exactly I'll need so maybe I can cut back on the truck's down time.

Radiator hoses, headers, Nelson harness, 97 2dr tahoe fuel pump and sending unit?
The whole fuel gauge thing is what is eating at me.....
I'm sure the physical part will be pretty simple and most of the wiring shouldn't be too bad.

In the link above I didn't see mount adapters for 88-98 trucks?

thanks
