    Dual Tanks Fuel switch delete

    Since you have a switch and they (at least mine) do not tend to stall in the switching process with engine running, what is the benefit of eliminating the switch. Looks like of lazy to me.

    What is this? Asking for a friend

    Hello Was this switch linked to the hood release? No lights come on when you pop the hood And I don't think our older trucks have a warning light when hood is in half way mode. About the cruise, I was thinking our new 1979 Jimmy had cruise control but after this many years and now having...

    question about gmc vs chevy

    Do whatever you prefer. GMC was considered higher level than Chevrolet (Professional grade they call it now). My 85 is a GMC but you can easily do what you prefer as they are similar.

    question about gmc vs chevy

    I remember they would come from the factory with wrong badges on one side. Just what they had on the assembly line as they were all built in same place.

    transmission oil change

    My friend helped me change Transmission fluid on the 85 GMC short bed and the 83 Blazer. Not because fluid was bad but pan gaskets were weeping. We loosened bolts on one side / corner and then edged that side down with looser bolts all the way around. We let it come out in a big pan on...

    running boards, nerf bars, step bars !!!

    I got Aries nurf bars for the 83 blazer. Did not try putting a set on the 85 GMC short bed truck as the saddle tanks would make it more difficult. The nurf bar idea on blazer is mount to body mount in front and back. Problem with right side is rear mounting bolt anchor in the frame does not...

    1985 K5 Blazer Silverado - NOTHING ORIGINAL!

    You got a great deal The engine and Tranny upgrade are great The glove box (RPO I think) shows you had a 4 speed automatic to start so if you went to 3 speed tranny it was a bit of a downgrade but my 83 blazer was taken from 305 engine and 4 speed AT to 350 engine and 3 speed tranny. Must be...

    Dual tank switch kills the engine

    I purchased the valve, dash switch and wiring harness if the fuel process / switch system is determined to be bad per our mechanic. I can return parts if not needed although maybe some day I will. Last week I put some fuel conditioner and water eliminator in the left tank to see if the...

    Dual tank switch kills the engine

    Thank you Grit Dog. I had the same thought as one possibility. I not only checked the left tank cap, I switched them Monday when I was doing more drive testing. Since reversing the gas caps (not same brand but look to have similar structure) I have not noticed any differences. Right tank...

    Dual tank switch kills the engine

    Hello. I am new to my 85 GMC pickup which just came a week ago. I love it as it reminds me of driving our new 79 Jimmy back in the day. This truck has saddle fuels tanks. I am not a mechanic. I love these older vehicles for the history as I grew up with my grandfather (a small town GMC...
