Ive just checked my petrol Grenadier and have exactly the same issue but there is no obvious place to effect a temporary fix. I’m a long way from anywhere and need to sort this before any more rough roads. I’ve had a few things coming loose and falling out. I will report later via the thread logsplitters travels as internet not so good here, so can’t trawl through every thread.
On the border with Namibia/Angola at the moment in the most beautiful location for a spot of fishing for Tiger fish once I’ve secured a radiator pipe fix.
