Oil Tank Connections - 914-6 Options

[DennisV]

I'm wrestling with some final bits of the 914-6 oil tank connections. Can anyone confirm these parts and / or share photos of them installed?

• 45: 901-107-281-00, circlip (oil filter console) - I took this apart and don't recall there being a circlip needed. Does it go around #46?
• 48: 901-107-696-40, Sealing ring for Filler neck - Seem impossibly thick to allow the filler neck to connect with the tank neck. I tried smushing it down in the gap between the body, but it just didn't seem right. See photo below for new part I received.
• 78: 901-107-679-10, Sealing ring (lower side hose) - I can't find this for sale anywhere, nor know do I know what it looks like or specs to find a suitable replacement.

Thanks for any assistance.

the circlip is used to secure the rubber collar. It's the same as what the 911's use. It goes inside the rubber collar - iirc.
The thick foam collar is correct. Some people just use foam tape. It's certainly expensive for what it is. It goes on the tank before it's mounted. So it's sandwiched between the tank and the inner quarter.
I'm not sure about the selling ring since I use A/N fittings but I seam to remember it's a second smaller foam washer. Could be wrong but I know there are two foam collars of different sizes. I have them in my stash if you need pics.

When you say "inside the rubber collar" is it the groove indicated by arrow in this photo?


A photo and / or spec for the foam washer would be super helpful.

Thank you!

Hi Dennis,
I think I have a nos #78. Let me check. I also have something else that is suitable. That circlip in the photo goes in that groove and pushes out. Text me tomorrow if I forget.

Hi Dennis,

Mark is correct. There's two foam seals (48 & 78) that slide onto the oil fill tube and lower return port on the tank. They get sandwiched between the tank and inner fender.
They are just a dust seal. The metal ring is used to hold the oil console seal in place. There's a groove in the seal that it snaps into and puts pressure on the seal to hold it in place. I made my own lower seal (78) out on some pipe insulation foam that's about an inch thick. I had some on hand but local hardware store should have something. Cut to fit, slide on return port and done.You'll have to push the tank into the inner fender to squeeze the seals and get the mounting studs through their mounting holes. My brother and I installed his tank this way. It's easier with two people. Hope this helps.
