1. My hazard flasher just died ( 1991 SWB) from an inadvertent short while fixing up trailer wiring . Fuse is OK so suspect hazard flasher switch( unit? module?) needs replacing. Looking/feeling right above interior fuse block there seem to be 2 relay-type inserts that can be wiggled but won't come out possibly becasue of a plastic retaining clip (
Can't see that well) Any advice on how to replace hazard flasher modules/units and are they readily available?

2. Just started towing 1600 kg RV and while performance is great, fuel endurance is down to 300 km/tank( 50 liter capacity or so). Can a larger fuel tank be installed with minor hassle? (say from the longer wheelbase Pajero, or are there aftermarket units?)

All advice gratefully accepted
