I was almost pleased when mine failed at under 25,000 miles with just a small leak from close to drain plug but definitely from the adjacent plastic to aluminium interface. Thankfully SiFab were still in existence and Simon provided a great service literally making one from scratch within a day and having it packed up and delivered in short order. Sadly we are only left with Mulfab now who I believe still shape the upper mount bracket to tank to allow a simple semi circular weld which has been known to tear the tank surface over time. This compared to Simons M shaped bracket allowing a longer welded seam to better spread the load as below.

Ironically he previously worked for Mulfab so maybe picked up on the need for this early on.
