Jobs done
Want to put a pic of the sensor installed in the sump here but I still cant work out how to get the pics to appear here. Look in my gallery if you want to see it.
Ended up getting a steel nut welded into the sump and sensor screwed straight in. So far no leaks.
The guy at Coventry fastners gave me the nut for free. Got the guy who did my exhaust system to do the weld.....he didnt charge me.
Total cost of the job = $0.00
Thanks everbody for your help. It's been an interesting thread.
