I'm the same, best thing Grippatank has done for me when fitting the system. Give Oliver a call at Grippatank but he is very busy so may need to wait a month or two.

Grippatank cut into the return fuel lines on my van and they had to be replaced they couldn’t or wouldn’t  fit a standpipe into the tank never did get a reason why , I got the standpipe fitted by a local Wabasto specialist, I think dazmond had similar with them they cut into a fuel line and either the heater or the van wouldn’t start ?

When my van was off the road for about six weeks I kept my important jobs going by using my wife's car - a little Suzuki Sx4 hatch  in which I put 4 x 25L barrels and an old shurflo backpack (18L) in the boot (so 118L total). I could have put down the rear seats and carried four more if I had to, but didn't.

The backpack was bungee strapped to a little folding sack truck. Would never use a backpack without a sack truck.

Put the backpack on the floor and filled from the 25L barrels.

Kept me going.

This is the kind of initial setup I was thinking of. 👍.
He's not in a position yet to go 'all in'.

Grippatank fit this as standard.

Small fuel pump underneath the van, tapped into your fuel tank, and it feeds off it that way.
