Why is the DEF tank on the right side?

Hello all. Why do some trucks have the DEF tank on the right side, when the DEF pump is on the left side? I look silly sometimes pulling in to the opposite side. Also half the time the gas pumps don’t even work lol. Maybe it’s bad juju 🤔

Better question is WHY IS THERE DEF

Mine is on the driver's side beside the fuel tank.

I've been in 4 different Petes. Currently in a Pete now & all but one had the DEF tank on the drivers side. No idea why the inconsistency.

Because it's added as an after thought where the space is.

The company I work for has a T800 with the DEF tank on the passenger side

There wasn't a standard placement of pumps or tanks initially. I've heard that the right side has been standardized for modern trucks.

The number of people who have put DEF in the diesel tank is staggering. Keeping them as far from each other as possible is a really good idea

Ford put the DEF nozzle on the same door as the diesel. The problem with drivers putting DEF in the diesel tank got so bad they 👇

Cover many claims under Warranty

And

Made it so that when the mechanic has to fix the problem they only order 1 part. Its a complete kit with the injectors, lines, filters and so on.

(My cousin who owns a construction company had this happen 3 times now. FINALLY and thankfully the trucks are now out of warranty and been Deleted)

was fueling up once and a driver next to me asked that i don't pull up when i'm done so he could fill his def which was on the passenger side. we talked for a minute about how stupid that was.
