Help with instrument cluster - 77 K10
I am trying to buy a new printed circuit board for my 77 K10. I had LMC Truck email me a picture of the boards they have for 77, but it doesn't match up to what I have. I found a number on my old board, and Googling brings this up, which is exactly what mine looks like...- Dleslie212

Trying to fix up dual tank fuel system
Bruce - Thank you for the response. Just reading about the path your wiring takes makes me think mine has been messed with. Both of my fuel sending wires run up the driver side frame rail. Also, each wire has probably three or four splices in it, that are just twisted together and exposed. No...- Dleslie212

Trying to fix up dual tank fuel system
I did find a few places online that show a picture of the correct single wire, six port fuel selector valve, but in every case, they listed the incorrect part number (the same is true for the WalMart link above, just take a look at the reviews) Unfortunately, before I even got a chance to test...- Dleslie212

Trying to fix up dual tank fuel system
Thank you. Unfortunately, I can't read a wiring diagram to save my life. It may as well be Chinese. I think I have everything figured out except the switching valve. I wanted to replace it, but it seem that the six port one wire valves are impossible to find anymore- Dleslie212

So then I should be seeing a single wire from each sending unit hding towards the cab to tie into the selector switch, and from there they head into the gauge? Thanks for the welcome!- Dleslie212

Trying to fix up dual tank fuel system
I appreciate the advice, but I'm just going to buy new sending units anyway. The one I pulled out already must have been original - the "filter sock" part is just shredded and the whole thing looks like it's in rough shape. I'm just going to buy two new units and the new valve, that way I know...- Dleslie212

Trying to fix up dual tank fuel system
I bought a 77 K10 a few weeks ago, and decided I want to start fixing it up slowly. The main issue I've been having is a fuel delivery problem, which I think I've solved with a new fuel pump. The fuel gauge does not work, and I think that's the next issue I want to tackle. The truck has dual...- Dleslie212
