Tank breather thingy

I have no recollection where this rollover vent valve was found many moons ago, but its finaly time for show and tell since now have a gooder tank for the rear.






It will tread into the given hole but not sure on sealing it. Is there room above this tank, so that a nut could be welded to the tank or dose some have a better ideal?

Maybe this plug is the ticket? Your valve sure looks different than my oem one though

Why not just buy a replacement vent, they are like $20.

This valve is 1in nptf, so its the right size to thread into the given hole nice and tight. Dont think that oem will work out, since this is not pushed in. So what I could think up, would be get this nut to have it welded on or just put jb weld puddy around to maybe make it sealed up.

I would like the oem off the cab and chassis, so that the tank is not relying on a dinky vent hose like what came with this truck. This uses 5/8 hose for venting, so maybe can fill the tank faster without triping the nozzle. This was what past me found, to maybe be a substitute for that cab and chassis one.

I will think about it, might be posible to file down the threads to make a nipple but need to check how much material I have to work with. My above though might lead to a miserable time making work with fishing my mitts in a tight hole, this spud work but would need to try an find how much room is above the tank. So will look into this and think about best outcome.

1in npt weldable spud

If it threads in tight, I would thread it in place, and then slather some seal all on it to seal it. It's resistant to fuel and works well for sealing against fuel. Making that vent larger does help with filling speed.

Yes it threads in tight, so I will try that thanks.

Got the vent tingy good and tight, then smothered it in the recomended seal all. So that leaves trying to figger out what is wrong with the sending unit, that was marked as correct...






So pryed out the old tank and fought with its unit, for somewhere over a hour and found the new one sundry enough that it aint a match...





Well, harvesting the old feed was not enought...





So tweeking the return, yeilds something that might fly and there set a infinitesimal amount off the bottom...





So now have a tank worthy of being shoe horned back into place...





When I had a gander at the pocket for the tank, there was enough rust that could not let persist. So might as well of set my self up on a turn table, when cleaning this up helter skelter. In the end, have some navel jelly slaped on to keep it at bay. So have to bide my time, before can slap on some piant. At this point, have gotten a fair bit of the frame painted and not going to do this section rite right now...








So if the frame is getting cleaned, could not leave the skid plate alone. This means need to find new rubber, before can the tank can go in.
