I must confess that the only 'breakdown' we have had in Pootle was running out of fuel - and yes, it was my fault Dear! Since fitting Tim's super new ali tank however the fuel gauge has been erratic - works sometimes but sometimes not. This morning I checked the cct. Disconnected the sender wire and feed from the gauge was correct at 10v but the sender was open-circuit (should be less than 300 ohms). OK so, drain the tank and remove it (again!).....At that point I should have checked sender again but I didn't so just took it out for a look-see. Opened it up and it's a modern copy of the old type - shocking design really but I improved the wiper arm and stretched the springs so it was 'better' but there was nothing much wrong to be honest..... OK refit and test then? When starting to fit it I realised what the problem was. The sender flange is isolated from the tank by a cork gasket and the self tapping mounting screws have fibre washers so the earthing of the sender was intermittant. Rather than just fitting an earthing strap I drilled out the mounting holes in the tank to 6mm and fitted M4 rivet-bushes then reassembled with M4 stainles screws. Jobs a gud-un and tested with a couple of gallons of E10 - need to get new mortgage for a full tank! Whilst on-the-job I replaced the fuel filter and last bits of old fuel line but noticed that the 45mm fuel filler pipe I fitted last year was all cracking from the E10 so have ordered a couple of Gates 90 degree pipes to replace that - fingers crossed!
