Rear End Vent Tube
In an effort not to hijack http://67-72chevytrucks.com/vboard/s...d.php?t=814572, I figured I better start a new thread.
I recently installed the snow plow on my pickup. Its a 1971 K10 chassis. When I got it most every part was cowboyed in place. I pick on cowboys because my friend that I bought it from purchased it in Wyoming where it was pieced together from many donors. Everything on the chassis appears to be from a 1971. 1/2 ton axles, half ton frame, etc. That all matches. While putting my plow on for the winter I noticed the homemade bracket that does the pushing and distributes the weight to the frame of the truck was broke. After a lot of telling my truck how I felt about it while welding it back together I noticed the vent tube for the front differential was broke in two in the process of massaging all that heavy iron. I'm guessing the cowboy that built this used standard rubber tubing on the axel as a vent because when you're a cowboy, why buy the correct part when you can make something else work? Then I read the above thread that I linked in. Do I order a pair of these: https://www.classicparts.com/1947-91.../#.VNwUcVKB_EE or these https://www.summitracing.com/search/...By=ProductName to do the job right in repairing that vent tube? I'm guessing the rear axel has a similar vent but I didn't look yet.

Re: Rear End Vent Tube
Sometimes, rubber tubing is used to raise the vent up out of the water. So, maybe a cowboy solution to crossing river/creek beds.

Re: Rear End Vent Tube
If you look at the Factory Assembly Manual on page 256, it shows that hose on the K trucks. Page 254 shows it for C trucks. It still gets the vent valve.

Re: Rear End Vent Tube
I can't speak to the K series trucks but I've had two C10's and both had rubber vent tube on the rear. No cowboy about it, that was factory.

Re: Rear End Vent Tube
I just did a complete rebuild of everything from the cab back and for the rear axle vent I used a piece of rubber fuel line with a tiny K&N filter on the end. Although the stock vent was way up inside the frame rail, I didn't think that was necessary with an oiled filter. Plus I can change it in about 2 minutes if I decide to.

I think what I'll do is order a pair of those vent tube ends and refresh both front and rear tubes/hoses. Thanks again. This forum rocks. Like usual.

Re: Rear End Vent Tube
Good point, although I don't drive in the rain and definitely not in deep water. Also, the filter is oiled which should help keep water out. I'll probably add a longer hose and move it up inside the frame rail just to be safe.
