Thanks Midwicket, I'll bet it's that. I had my back seat out at the weekend as my 5 year old spilled milk and I wanted to clean it before It turned rancid. I notice that the sheet metal had been cut around the sender access panel.
All others, turning the nozzle 45 or even 90 degrees helps, but doesn't cure the situation.
As for paying someone to look at or work on the car, forget it. The only time anyone but me works on a car is if it's for warranty. I'm in Michigen so no emissions testing, I'll just live with it.
Thanks
Adrian
