    350 Water Pump Woes

    Are you purchasing remanufactured Napa pumps or new? If they are remanufactured they might have all ready had pin holes in it, that they patched up during the remanufacturing process and didn't do a very good job. It look like Gates make the new water pumps for Napa and rayloc the reman'ed...

    Adding 81-82 bumper fog lights

    Can't be much, but I also can't think of a time I've needed to know (practically). At least in wiring to the parking lights instead of the actual low beam wire I bet you dim your headlights a lot less, but ya I get the ease of installation, or speed of installation sometimes is what is needed...

    Adding 81-82 bumper fog lights

    Well that is true too, I don't disagree, but the point we are all trying to make is the pewny headlight wiring is designed for the headlights only. Give it a shot sometime, turn your headights on with alligator clamps hook a set of hella 550's to your battery and make note of how much your...

    Do intermittent wipers use a different wiper motor?

    As far as I know Dave is correct, but I'm also going to draw @Doppleganger Chris in because I know he knows these wiper motors inside and out. I will also add that the intermittent modules are not very reliable and prone to failure. You will need an intermittent switch as well. What I would...

    Adding 81-82 bumper fog lights

    One comment on wiring them into the low beams, Like Grit said the way to do it is to wire them so the low beams trigger a relay and the fog or droving lights are powered separately. If you were to wire them directly to the low beams you'd tax the old wiring and at the very least dim them down...

    Wireing help please

    I was thinking the one in his hand is oil pressure the other is HEI power, but he says the oil pressure gauge is hooked up. Base info on the truck would be helpful. Maybe a picture zoomed out a little more might help. Does the truck have a factory tach?

    How many gallons can you put in your gas tank?

    Of course I bought my truck used and had different wanted specifications, like I wanted a C/K 20 or 30 but the only option I had to have was A/C.

    Heater Core how to

    @Soundmound no they are not suppose to hiss. I have no idea where you'd get a replacement other than Greg's link.

    How many gallons can you put in your gas tank?

    As far as I know what you have said is correct. All the truck C/K 10 - 30 will use the same resistor because they have the same sending unit, the C 50's & C60's use a different resistor, the Blazers and Suburban's I think use the same resistor but is different from all the others. I also...

    Heater Core how to

    We I hope someone better with blend doors than me chimes in. One of the problem is blend door issues are so rare on these trucks I haven't had to do much. Like I said if it was in front of me I'd fart around with it until it was right, but it's hard for me to advise you. What I can advise you...

    Heater Core how to

    @Soundmound Which blend door are we looking at? To be honest with you I'm not the best with blend doors unless they are in front of me and I can move stuff and see how it is working. But I will add this, if you marked all of the rods and such when you disconnected things and it worked before...

    How many gallons can you put in your gas tank?

    Ok here is a story for you. My Dad bought a 78' K20 in 80'. Since it was the newest vehicle my parents owned, we took it on a lot of trips, three of us in the cab, Dad, Mom and me. Dad bought a canopy for it that he'd put on before these trips, so there was no passing the nozzle from side to...
