Home made auxiliary fuel tank

[MetrickMetal]

I needed an auxiliary fuel tank for checking the float bowl fuel level as well as when running the engine when I sync the carbs on the C10 I'm resurrecting. So rather than buy one, I decided to make my own out of a good heavy duty 1 qt HDPE bottle I had sitting out in my shed.

I drilled a hole in the cap and machined up two aluminum adapters that bolt to each side of the cap which are sealed by two Buna-n o-rings. I drilled a hole through the center of the S/S button head bolt for the fuel to pass through, and it's past an over night leak test.

To mount the bottle to a stand I use in my shop that already is used to hold my powder coating oven racks as well as my carb/throttle body sync gauges, by machining up a simple 1/8" aluminum plate that the groove on the neck of the bottle slides into. The small round aluminum piece with the hex machined onto the end is a screw in safety stop that keeps the bottle from sliding out of the bracket when in use.

All I have to do not is pick up a section of 1/4" fuel line from the auto parts store and an in line fuel petcock and it's ready to use. I also just remembered that I need to put a small vent hole in the bottom of the bottle to allow the fuel to flow, so I'll machine up some aluminum pieces like I made for the outlet sealed with o-rings and a 1/8" pipe plug that I can remove to vent the tank

How can a carb sync gauge which I already have a custom made one I built be an alternative to a auxiliary fuel tank?

There is also a auxiliary tank idea on that page.

Opps, now I see it.

Many ways to do this, all inexpensive. I have seen a mechanic use and old coffee tin with a nipple and plastic tubing in the bottom, and a wire handle at the top so it could be hung over handle bars.

Nice, looks a lot bigger than a quart.

I just use an old overflow container I have from my ZRX.  The fuel line just clamps on to the bottom nipple and I hang it from the rafters (of course I capped off the upper overflow nipple and install a fuel shut-off valve about 3" from the bottle ).

That's a really nice set-up you made "MetrickMetal".

I got ahold of a few of these:



I cut the bottom off of one, ran a zip tie through a coupla holes I punched in the side near the bottom. I hang it from the bars with the zip, bottoms up, hook up a 3/16ths clear hose that fits inside the Conc's fuel line, and stick the other end on the nozzle. Then put some gas in it. Yeehaw!

But what do you do with the mustard.

As the pic below shows, I made an aux tank that looks EXACTLY like the OEM fuel tank from my Connie.  In fact, you can't tell the difference.  If I run this one dry I have one from an old Sears lawn mower that uses the same hose size.  Like the inventive genius behind the others, though.

Why, of course it went on the beer brats.
