    Looking for smog parts for 1977 gmc c25 w/454

Does anyone know of a comparable that will function properly? The original part number is GM 17094028 Also need a diverter valve, anyone got...

    Ok got it, thanks so much for the clarification. I’m starting to understand better now they used two because the 6 port is basically discontinued. Is there any way to test those before putting back together? Is it safe to run all hoses in rear end or do I need to use cross over hard lines from...

    Faulty rigged

    I have to empty one of the tanks full of old fuel and inspect it. Now you got me thinking maybe I should run them both. I was just going to buy one new tank. But if the two I have are still good maybe I should put them back if they have that 1 wire switch. Did you run two hard lines across to...

    I’m just going to put one tank back in on passenger side to make it easier. I see they have a 20 gallon on rock auto, have to check if it will fit in place of the 16. With a new tank and fuel pump up front and carb with a new canister I’m hoping that will fix all my gas problems and hopefully it...

    Faulty rigged

    Update:I have removed it all. This is what they had going on connecting across both tanks. Also removed both fuel tanks because I have it parked in garage with water heater and was concerned about all the fumes the space was filling up with. So I figured I remove it all and inspect everything...

    Yes they put two fuel pumps instead of original valve. Some of the rubber hoses were leaking where they clamped onto hard lines. So I removed it all, time to get it all safely buttoned up

    Faulty rigged

    Just picked up this 77 c25. It smells of heavy gas fumes. I got under started looking around. Apparently they removed all the cross over hard lines to dual tanks and ran all rubber hoses. The original switch valve has been removed and replaced with two small pumps for sending and return. They...
