Ah, the perfect tester! Did you do the mod pretty much exactly like CFlyr posted?

Pretty much yeah.

Kartman, what rearend does your truck have? You seem like you push it to the limits, just curious if it's been replaced or if you have an upgraded unit or what?

factory D44 with a truetrac and some gusseting on the lower shock mounts.

I wouldn't admit to blowing a couple seals! PITA will track you down!

I have now been to Ace, Menards and Sears looking for this 1/8" hose adapter and have yet to find it anywhere, all I can find is 1/3"! Has anyone come up with a different silution for this, or do I just need to order these little parts online??

I bought one Friday at Autozone.

MPT (male pipe thread) = NPT (national pipe thread) I think MIP is also the same thing.

So if you find 1/8 MPT (or NPT or MIP) to the hose barb, you are good.

Makes sense! Only delima now is, what size for the threaded side? The 1/4"? I'm pretty sure you're right though, just looking at the threaded side that is on the package.

I just tried the 1/8 MPT to 3/8 barb. It is a little tight (although the brass would probably deform into conformance with the thread tapped into the steel of the axle housing).

Maybe 1/8 BSP (british standard pipe) to 3/8 barb is the actual size?

OK, after searching this forum, it appears that the correct thread size fitting is Toyota part #9040451026 which goes for about $3.00.

Cool, I had the same problem. Part I bought from Ace wouldn't thread in.

Perfect, thanks!

Has anyone done this mod that can give a part number for the barbed fitting?

Toyota part #9040451026

3/16" fuel line

1/4" to 5/8" range hose clamps

FF2314 G6529 fuel filter

Everything from Autozone except the Toyota fitting (threads match perfectly).

I must say this is a great mod. I must also say that my axle did not have a vent in it, all it had was a plastic threaded plug, no vent at all, when I removed it, the axle had at least 30 psi of air trapped and expanding in it. I removed the plug and the air rush out of the hole was so great that it literally whistled and decompressed for at least 3 or 4 seconds! HMMMMM, I wonder why rear axle seals are failing?

I purchased the recommended Toyota nipple and parts listed in this thread. They all worked well, no issues at all with the installation. I made sure to leave a jounce and rebound coil in the vent hose using the natural curvature of the hose to create it. I then followed the factory wire harness to the rear of the truck using its clips to provide the support for the vent hose. I also placed two feet of convolute on the hose to insure that it would not chaff on any of the sheet metal or the bed mounts. The hose was tight enough that it really did not need any hose clamps to hold the filter on. It will need to be cut off if I ever need to change it. All in all this should save my rear axle seals from failing, I’m surprised they had not failed with the amount of air pressure residing in it.
