When my gauge read 1/4of a tank left , it runs out of fuel . Does anyone know how I can cure the problem so that the gauge can read correctly

So I want to replace the fuel pump and filter on my Alphard (ANH10, 2006). I understand that access is via a hatch under the floor behind the front seats. Unfortunately I've got lovely flooring in place which was done as part of the conversion to a camper.

Alphard 2006. MOT from February this year advised "Axle swivel pins and bushes swivel pin and/or bush slightly worn Rear (both rears slight cracking)[5.1.2( b )( 1 ) ]". A couple of local garages will not touch an Imported car. I think this should be a common maintenance job. Any help guys ?

Hi I’ve recently removed my rear conversion from my 2006 Alphard . Reason being we bought a Rhodesian Ridgeback and quickly realised the old set up did not work ! I’ve swapped it out for a full size rock and roll bed with no units . The rear conversion was bought from First Cut campers . It has everything you need to turn van into camper Units Cushions Sink Dometic sink / cooker Waste fresh water tanks 2 gas bottles Table Control unit for electrics If anyone interested I can uploads pic

Engine Light was still coming on after driving for a while (30 minutes or so) and the Ancel JP700 scanner showing P0171, but fuel consumption was so much better and had other things to
