I filled SWMBO's 90 up with diesel until the pump clicked twice to say it was full.  :lol: 
Drove down the road and the rear and side was covered in diesel.  :shock:  :oops: 
I did remember that when I removed the filler cap at the garage it was under pressure.  :?  When I took the cap of back home it was under pressure the other way and shot some diesel out.
Anyone know what is wrong? Cap rubber seal looks okay.
