Yeah, I just discovered a Speedway glitch myself this week. I bought a 0-90 ohm fuel tank sending unit from them over a year ago and installed it but just got around to hooking a gauge to it. The gauge wouldnt read right so I pulled the sending unit out to check it and its a 33-240 ohm unit. Wish I'd have checked it when I bought it; too late now.

Your truck looks great, BTW!
