PROJECT-A-PALOOZA!!! -- Aux Fuel Port

Hey all! Another project....


I wanted a way to use fuel from the main fuel tank for various "accessories", instead of having to carry gas cans, etc.

I created an auxiliary fuel port on the starboard side panel of the splash well (it's the little orange thing in the photo).

Here is a closer look. I used a Honda outboard tank connector with 1/4" threads. The cap is a plastic/rubber thing I had that just happened to fit. It will surely degrade quickly and I'll have to find something else....

This is the backside. I used a bulkhead fitting with 1/4" threads on both ends internal to an outer tube with larger threads and a bulkhead nut. A 1/4" barbed elbow fitting was then used to attach the hose. The bulkhead fitting came from http://www.mcmastercarr.com.

Here is what the Honda fitting looks like without the cap, threaded into the brass bulkhead fitting. There isn't much "shoulder" to the brass fitting, so the hole has to be quite close.

I bought the mating Honda barbed connection to use with a hose.

Then I made up a section of hose with a primer bulb to pump gas into all of my accessories. This stows really easily, once drained thoroughly, in a bin near the main gas tank. It was important to get a good primer bulb to pull the fuel up from the main tank below, especially when there was only air in the line to start with. This one from Moeller worked really well. http://www.amazon.com/dp/B004APHPMM/ref ... 1_ST1_dp_1

Finally, I split the output of the Racor into a threaded Y-fitting and put two valves on the outputs, one for the main engine, and one for the auxiliary port. This way I could shut one or the other (or both) off independently.

And here it is in use! Filling the internal tank of my little dinghy outboard. Works to fill up the Honda EU generator, too!

If you keep a spare Racor with its bowl on board, you can also use this to pre-fill it prior to a filter change.

Hope this was useful! Pics and descriptions also on my Mods page.

I can see the resourcefulness and application. Great idea. :thup

I can see where this would be a nice means to refuel a portable genset if it were not directly cut into the fuel system as you noted.
