1020 gas fuel pump back-up wrench?

hardpan99 · Aug 16, 2016

I just got a new fuel transfer pump from deere for a 1020 gas. A note in the box says it must be installed using a "back-up wrench". It doesn't say if its needed for the mounting bolts or the fuel line connectors. Anyone have experience with this?

when I have heard the term "back up wrench" it usually refers to fuel fittings. using a back up wrench so you dont twist on the wrong place

Backup wrench would be needed for fuel line connectors not mounting bolts.

The Airtex pumps that were not cast especially
needed a "backup" wrench to keep from buckleing
those stacks.
On all pumps you need to hold the fittings to
keep from loosening the adapters.
