Battery drain & blowing fuel pump fuses

[Gizmo3]

Battry drain

I have a 1993 Nissan pickup king Cab. Best truck I ever owned. I have put four hundred thousand kilometers on it and it still runs like new.

BUT!!!!!!!

Last winter it started blowing fuel pump fuses all the time. Well after three months of rewiring I found out that these trucks had that problem.
It was the sending unit. This is for your information.

This is my problem this winter. Battery drain. All of a sudden it started draining the batter over night. Get up in the morning and the battery is dead. Now before I spen another three months rewireing I thought I would ask. I know another nissan owner of the same truck and he has the same problem and cant find the drain. This maybe sujest that it is a common problem again with these trucks.

Hope ya can help
