Description:

I purchased this due to an unidentified coolant leak on my 912ULS - thought it was my expansion tank... turned out to be a fine hairline crack in the separate plastic overflow tank with the fluid flow taking something of a mysterious path that made it look like it was from my expansion tank. Hence one spare tank.

This tank has been checked (leak test and borescope) and all welds are good

Overall - this was purchased new but turned out not to be needed, and just taking up space in my flight locker. Retails at well over £400.

Full unit - expansion tank, new pressure cap, and base protector pad (see photos)

Sold via ebay for convenience.

Price: £295 + Ebay fees
