Mounted the tank on 5mm rubber pads stop vibration and allow expansion and movement
The new feet are welded and secure
New spout takes a 2 inch hose and pipe work will link up to the filler.
The height of this is to prevent slosh back even though the tank is foam filled liquid will naturally try to fill the tube. It's cut out inside so will easy flow enough from a pump. The beveled end may be ott but it only took a minute so why not!

Hmm I'm no expert but when I put my turbo engine back together I didn't have mine resurfaced, albeit it looked a little less marked up. How old is the flywheel? Mine had been resurface about 4000 miles previous though so if this is the original flywheel you might want to for peace of mind.1990 325i Touring - The Bonsai Bimmer - Patiently Waiting
1984 316 Coupe - The Base Model - Pain in the Ass
1988 750iL - The Daily Driver
...And a couple others...
