Auxiliary tank

[Chester allen]

Hello classic bronco family i got my hands on a steel auxiliary fuel tank it is bigger then the stock one for my 75 and the straps don’t fit around it. There are no mounting tabs on it at all so makes me think only way to hold it in is with straps. Does anyone have this gas tank in there’s if so please share. Thank you

Mine is held on with two long pieces of all thread and nuts from the drivers floor right through the middle on the tank to the bottom.

I ditched my aux tank years ago and later installed a 23 gal rear... one of the best mod/upgrades ever for me!

Bought ours with stock aux tank and 23 gal main tank. We'll be removing the aux tank. It's just not needed.

First bronco was a stock rear tank only. That sucked
Second bronco it was mandatory to get a dual tank vehicle. Got it, used it.
Put the 23 gallon in the back. Turned into a chore to run the gas out of the aux tank before it turned stale. Was getting close to deleting it when I sold it.

As for installing an aftermarket aux tank. We can guess it is one of the old Aero tanks? Or maybe something fabbed up by a local gas tank shop, lots of those were made back in the day. We don't know. Most of the ones I have seen were built as a one off by a local shop. I really don't think I have seen an Aero aux tank in person. Really doesn't matter. There is no off 'just do this' to make it work. You need to pick up some metal stock, some all thread, and pull out that creativity they taught you back in arts and crafts class. Apply a little common sense. And you will have built your own gas tank installation kit.

I had 23 gallon tank with EFI and elec fuel pump installed and told by installer that I would have to add an electric fuel pump. Is there any other strategies to utilize the aux tank?

I don't understand the question.

You can either make longer straps or fabricate a bracket that bolts to the frame. At one time I designed rock bars that held the tank, but I can't find the design anymore since I went in a different direction. I'm fabing brackets which bold to the frame but have not done the work yet.

I have a similar set-up. I have an external Carter low pressure pump which pumps from the 23 gal rear to the tank switch. You can run an internal one. There's a 20 micron filter before the Carter. I believe this was a requirement for the Carter. After the switch I run to a high pressure Bosch and then a 10 micron filter, these are requirements for the Sniper. Although I've heard people run the high pressure only, these are basically pusher pumps, not draw pumps. The Carter is a draw pump. My aux tank is gravity feed to the switch where it's picked up by the Bosch. Since it's gravity fed, the Bosch doesn't struggle to draw.
