    Proportioning valve vs. load sensing valve

    Just for closing this case for now, i bled the whole system again with approx 1,5 quarts of brake fluid. Also bench bled the MC again while it was in the truck. Problem seem to have vanished for now, but will keep an eye on it. If it happens again there must be a leak somewhere.

    Verify defect fuel sending unit

    Thanks. Looks like dropping the tank is the best alternative for me, if needed. I will be checking the wires to and from the sending unit (if I can find them). Pink wire from the dash, through the firewall and all the way back to the tank switching valve? From there it changes to tan, and then...

    Verify defect fuel sending unit

    Hi guys, Original dual tank setup. Right side tank fuel gauge peaks at 3 o clock when selecting that tank. Removed the chassis ground and worked everything with the wire brush, then reattached. Still same problem. This verifies that the fuel sending unit inside the tank is faulty? Check my...

    Proportioning valve vs. load sensing valve

    Well, I started from scratch again and bled all the brakes. I managed to get the rear brakes working again, but still a huge amount of air in the system. I noticed a little «volcano» erupting in the front reservoir in the master cylinder when i pressed the brake pedal. I disconnected the lines...

    Proportioning valve vs. load sensing valve

    Seems like theres different opinions on that Yep, rain and snow has gotten the better of us i southern Norway the last couple of years. Recommend you travel north the next time - nature is at another level. Also spare parts for these kind of vehicles are available, but often from the states...

    Proportioning valve vs. load sensing valve

    Ah, OK! Anyone with other thoughts on the problem? Could it be wrong cylinders in the rear?

    Proportioning valve vs. load sensing valve

    Thats the thing. Some people say this and other says the brakes got better after removing it. There even was a GM service bulletin to remove it. Do you know the load capacity for when it was triggered?

    Proportioning valve vs. load sensing valve

    Thanks. My bad, but the pedal is not going to the floor, but as far as it normally do. I did take notice, as there were a little sticker on it, but it seems like this spins freely with maybe two positions. Plan was maybe to delete the whole load sensing valve.

    Proportioning valve vs. load sensing valve

    Been doing some brake work on my truck recently. Had some issues last season and recently replaced all the hardware, shoes and cylinders on the rear wheels. Also replaced the master cylinder and the two lines to each wheel since the old lines where so stuck in the cylinders I had to grind them...

    Tach wire and relay

    Allright, thanks. The truck does have HEI. So i will need to look under the dash probably, as it will lead all the way there?

    Tach wire and relay

    Not sure what you mean? In the pictures I posted you can see the cable connected and disconnected from the tach-slot at the distributor cap. Am I missing something here?

    Tach wire and relay

    Hi friends, Was thinking about wiring up a tach on my 85 GMC C25, but when i looked at the distributor, there was already a cable connected. Where does this lead? The truck has both AC and Cruise control. Both are partially removed for various reasons. Also, whats the function of the relay...
