For some reason, the oil tank breather and the gas tank breather set-ups have taken me a LOT longer to sort out than I thought they would. So, I will do a bunch of pictures and try to articulate why I chose to do what I did.
First up, the oil tank breather...
After way too much time searching, this is the tank I settled on. $80 for something like this seems real cheap to me, so this was a "buy" versus a "make". The part number for the tank is STF-5116:
In this case, size did matter to me (both overall and the fittings). I had a couple locations in mind for it in the engine bay (outboard of the RHS rear shock mount or on the RHS wall ahead of the oil tank). Both spots would be a tight fit and the ~1" ID hose coming off the oil tank is pretty big (for good reason, of course). I didn't want a bunch of adapter fittings in the set-up and my preference for the location was just ahead of the main oil tank on the RHS... wanted to use that factory S-hose if I could, too. So, the 5116 fit the bill regarding size and fitting location/size... what finally made it work for me was that it came with a -12 AN fitting on it. Just so happens the OD of the male threads on a -12 AN fitting are 1.0625"... nice for that 1" ID line!
So, here are the parts that will get installed and the gear to pull it off:
(Like that donor bracket... license plate bracket from a trailer IIRC... should be able to get a couple parts out of that!)
Here is where I want it to be:
Rivnuts to the rescue again:
Support bracket made, painted, and in place:
And everything installed:
FYI, that S-hose is part number 911.107.393.01 (usually used to go from the oil tank to the RHS of a CIS air box).
REALLY glad that is done. Options down the road would be to add lines from the breather tank to the carb air filters to burn off the oil fumes (hope I don't smell them in the car with the heater on like I have read about) or mod the -12 AN fitting if I get a leak where the S-hose hooks up to those threads. All possible since the tank was made of uncoated aluminum and I have a friend that is good with aluminum welding. Those were 2 other reasons I went with that tank...
Hope that saves somebody some time!
