Okay, technical question here:

Why is there a rusty steel insert in the filler neck of my washer fluid tank (insider the passenger fender well)? I took out the tank. Cleaned out everything today, lines, pumps, tank everything and chiseld out the rusted hunk of crap that was the steel sleeve in the filler neck.

Do I have to have this insert thing here? If so, why? It's not like we are clamping down a pressurized radiator system here. The hose clamp holding the host to the filler neck just has to be a little tight.

just clean out your tank with some small rocks and simple green and hot water agitate for a few mins then rinse clean.
Remove the metal collars from the fill tube and the tank first, refit the tank and snug the hose clamps. As you have figured out there isnt a need for the metal collars just dont overtighten the clamps.
If your fitting a new fill tube dip the end in some hot water first then slide the metal collar out

Nichole, thanks for that info from Schocki, it will be this weekends project.

Not very clever of them to not make this tube out of stainless...what $.50 more expensive?

That's what you need to do...go over to your buddy at the local machine shop and have him make a couple of stainless inserts...

Please don't install a socket...we'd have to come and take that car back.

Would aluminum work also? It may have to be a bit thicker.

GregBBRD

Aluminum is going to oxidize in that environment, too.

304 stainless is so easy...

Mrmerlin

nothing works pretty well

No socket for me, just remove and forget about it.

Couldn't believe how much stuff in the bottom.

Cleaned it out with Hot water, rice and baking soda. It cleans it out pretty well. That's what I use to clean my bike water bottles that get moldy.

Did mine a few months back - the smell of the tank contents was so bad it had me tearing as I removed it to clean it out. Seems like a common service item especially among newly acquired 928s.

To be clear, you don't need that metal peice. Just remove it and forget about it.

Hey, you found a weight loss opportunity! Do the track car guys know about this?

I just used pieces of PVC pipe on mine. Why go with any metal?

I don't know about washer tank fittings but stainless fittings for coolant systems on aluminum alloy engines is a no-no from what I read. Galvanic voltage is 0.5v.

Mine was growing slime. Any suggestions on an additive to keep the bacteria dead? I'm thinking about a little alcohol added to the washer solution?
