Fuel tank filler caps distorting
« on: June 08, 2024, 03:06:10 PM »
Here in the UK we have recently changed to E10 as the new standard petrol, E5 is still available but it is now the premium grade and a lot more expensive so generally I run on E10.
Last time I fuelled up I noticed the tank cap was a bit difficult to remove, on looking closer it appears that the plastic is swollen and the seal was in a bad way, these were new Stant locking caps fitted about a year ago, just wondering if anyone else had found this problem?
!976 Chevy C10 longbed with twin tanks.
Is there a metal cap available which might withstand the fumes of this awful E10 which we are forced to use and should it be vented or not?

Thanks
Graham

Cheers Vile, are there any metal caps available that should withstand this E10 better?
