fuel tank sender inspection

[kap]

I was woundering if anybody here could tell me if the later vans have a hole in the cab floor to inspect sender,all I need to do is touch the two wires together to see if the senders suspect,i dont fancy dropping the tank if it can be avoided.

I'm pretty sure no vans have this, removing tank isn't as bad as it sounds, obviously use as much fuel as possible, make sure when refitting tank it goes up front first, other wise it fouls a front cross member and is impossible.
