They are concerns others have expressed over the years.

The transfer pump was cactus in my disco when I brought it. Had to remove the LRT to get to the pump to replace.

What tank brand was that? I can change mine where is...

Its an LRA tank. Pump is mounted behind the rear diff and in front of the tank

Yes, sounds like the Long Ranger tank as well..

Why couldn't you change it without removing?

I was supplied the original pump with the tank, which failed 5 minutes after fitting - took 2 spanners and about 15 minutes to change in-situ...

But it did wear a phenomenal amount of Diesel - due to the tank being full to the brim

Couldnt get my hands anywhere near the pump

As I understand it, the gravity feed has had a valve for some years that prevents fuel from. Running back from the main tank when on a steep hill.

Not sure about the concerns re isolating are about. The electric pump tank sits in the same place as the gravity feed so holing is just as likely (not very given the construction of either of these tanks). If you get a hole in the main tank then it doesn't much matter.

So I don't understand the perceived need for isolating, but am happy to be educated.

Love these discussions by the way - so much to learn.

If you hole your main tank with a gravity tank what happens?

Good point.
