Grippatank fit this as standard.

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

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.

I’ve just had a look at the link to the backpack….IMO that backpack is as good as useless for working with all day. You really don’t want to be working with a backpack ( they should be renamed😁 ) on your back. When it’s full of water it’s over 25kg, that puts a big strain on your back and neck, especially when you’re doing upstairs windows.  If he must go down the backpack route he’d be better with a Gardiner style one which has a carry handle.  Yes it can be heavy to carry if using without a sack truck, but at least you can put it on the ground when you’re cleaning the windows.

Yeah, I don't think he intends to put it on his back. 👍

Most put them on a sack trolley not on there backs due to weight

I used to carry my one, point being the one in the link doesn’t have the option to carry it as it doesn’t have a handle.
