Extended run fuel tank for Yamaha EF2000IS generator

No Princess Palace on station.  11/01/2014

No Princess Palace on station. 11/01/2014

I guess quite a few folks who visit here prefer my DIY posts over the ones where I explain the meaning of  life, solve all the problems of the world or tell you how to be the world’s greatest lover.  Go figure!  So for those of you who like tales of living in the South Texas puckerbrush as an oilfield gate guard;  this are one.  These prove tedious to me what with all the links and such.  Many of the links track back to Amazon (you know what to do) as it is a main source of supplies and goods.  Hell, we get UPS and FedEx at the gate and I have my UPS driver’s cell number in my phone.  Called me yesterday to see if he could drop my packages at the Ace Hardware in Cotulla since he wanted to get home early to go trick or treating with his kids. Don’t you love small towns?

There are items I deem indispensable if you are fulltiming, boondocking or living life as an oil field gate guard.  A generator would fall under the category of want  — not need.   I have had a generator since day one of my RV life .   The Old Girl had a propane fired Generac that had its’ ups and downs.   There was the diesel Green Monster that required its’ own trailer and industrial ear protection within 50 foot.  It lives in New Mexico now pumping water out a deep well.   My current generator is Little Blue and you might say I am in love.

Little Blue is a Yamaha EF2000iS 2,000 Watt Gas Powered Portable Inverter Generator and I have had it for almost a year now.  Maybe you clicked over to the link and saw what it cost?   Yup,  you can buy a Chinaman generator at Costco or Sam’s of equivalent output for less than half that cost.   Now listen, we have been over this time and time again!  Jeez.  Buy once.  Cry once.  My idea for a generator’s necessity is not to run the blender to make margaritas in the Rose Garden when I am lounging in the Gazebo.  I need a generator when I plug my shit into the wall and it don’t work.  In other words,  something serious has occurred to my personal power grid and it is no longer functional.   When that kind of serious bad juju rains down on my head and all that stands between me and a freezer full of ruint food is my generator,  I am going to be glad I ponied up those extra bucks for the most reliable generator I could get.  That would be one of those “this is how the cow eat the cabbage”  moments for those of you who require additional persuasion.  Just sayin’………

I added a few things to Little Blue to up the ante even more.    A Yamaha Generator Cover to keep the caliche dust at bay — a little, a magnetic dipstick since there is no oil filter and a Yamaha Automatic Deluxe Hour Meter that also reminds me when it is time to change the oil.   My Bro has his own Little Blue that lives at the Secret Hideout and I bought a Yamaha Sidewinder Parallel Cable 30AMP RV to tie the two generators together.  Do that and you can run everything in an RV including the AC.

Little Blue just sips that fuel; about a coke can full each and every hour.  Only bone I have to pick is the runtime is just inconvenient.   If I fill it up in the evening, it runs out some time before daylight.  I needed a little piddling project to keep me out of the bars here of late so I figured I would come up with an extended run fuel system for Little Blue.   I figured a 5 gallon can oughta run me over two days continuous.   That should about do it!

NATO Jerry Cans in the back of the Big Ass Suburban. 10 liter in front, 2×20 liter behind

Some years back I got sick and tired and just plain fed up with the sorry state of affairs as far as gas cans go around here.  Sorry rascals.   Gas ‘cans’ are plastic now and the UV eats ’em up.  If you store them inside out of the UV, they leak fumes and are liable to blow everything RTF up….  and with all that CARB nozzle crap, they pour gas like ass.  I don’t care how you hold your mouth, you are gonna slosh some gas out.  The final straw was when I drug out my little 2.5 gallon spare I keep empty in the Big Ass Suburban and started to fill it up at the Pilot.  Sorry bastard had a rub hole in the side of it from jostling around in the truck I reckon.  I threw that sorry mess in the garbage and decided to remedy the situation ASAP!

The answer was a 20 liter NATO Jerry Can .  All steel welded construction, no CARB nozzle nonsense.  These babies will empty in a little more than a minute!  No fumes, no leaking, you can lay ’em down flat, stack ’em up  –whatever.  They take a licking!  Yeah I know they aren’t cheap but do like I did.  Order a few here and there when it crosses your mind and pretty soon you will have a whole herd of them.  You may see them listed as ‘water cans’ because they are not CARB compliant and they will store water if you are so  mind.

Since I already had these Jerry cans, it was a natural to use them for the extended run fuel tank.  This Jerry can adapter made that possible.  The plan was to use an extended run fuel cap on Little Blue and the Jerry can adapter on either a 20 liter or 10 liter Jerry can with quick connect Marine fittings on each.  In between would be a fuel bulb to prime the line and an inline fuel filter on seven foot of hose.    I definitely thought I had it all dialed in.  I didn’t;  it was a miserable failure!

IMPORTANT NOTE:  Fuel lines are fuel resistant on the INSIDE where the fuel is.  The outside is NOT fuel resistant and will melt if submerged in fuel.  For the fuel line that goes from the Jerry can adapter down into the gas can itself , you must buy submersible fuel line and it is NOT cheap.

I hooked everything up and cranked Little Blue over.  The tank was showing empty.  I set the Jerry can up higher on a table so it would facilitate suction and then stood back to observe what was fixin’ to happen.   Little Blue does not have a fuel pump but I figured out that if the engine was running, it would create a vacuum and draw fuel out of my can if all my connections were airtight.  About 3 minutes in I heard a gurgle and noticed the fuel gauge rising on the the Yamaha generator.   I was thinking “you smart sumbitch. You!”  Once the tank filled I knew the suction would keep it full.

Well sir, the tank filled right up and then proceeded to leak gas everywhere.  I just knew I was going to get blowed right up ’cause Little Blue was sittin’ there jus’ running right along.  I scratched my head and took all that fancy stuff off and stripped the rig down and got it running — after a fashion.  So I know the concept works.  The rest of it has been filed under EPIC FAIL.   I think I know what I did wrong.  More next week……

    In the ‘for what it’s worth’ department-
    I added a vent to a plastic gas can. Here is where I saw it first https://www.youtube.com/watch?v=0lcnwdIYEfI .
    It’s cheap, simple, quick & works.

    I look forward to you Explaining the meaning of life, solve all the problems of the world or tell you how to be the world’s greatest lover.” Never was much good at any of these and welcome all the help I can get.

    Fluids in multiple containers connected together will all equalize to the same volume height. I think this is a law of gravity. Suggest the you get a Y valve. One side goes to the internal tank. The other side goes into the Jerry can. Let the Jerry can run low and switch back to the internal tank. Then disconnect the Jerry and go refill it. You might be able to use the reserve valve off a motorcycle.

  • Well, at least you weren’t blowed up. Like Wormtongue’s party was Tuesday. Heh. You don’t deserve it. They did.

    Hey Dude! Long time not see! Got an idea for you on this little blue gen set extended run thing. You already are using the marine quick connect. Might I suggest that you just go ahead and get a 6 gallon metal marine fuel tank, disconnect the fuel hose between the carb and the built in fuel tank on the gen set. Run the end of the fuel line from the marine fuel tank to the carb on the gen set. Bypassing the onboard fuel tank alleviates a lot of risk from leaks and over fill. Just a thought. Use the Jerry cans to store fuel in and to refill the marine tank. As long as the marine fuel tank is set up higher than the gen set, I figure once you squeeze the primer bulb a couple times the little gen set ought to run until the cows come home or the light come back on.

      Hey Clay!

      Hope everything is good with you! I am re-evaluating the whole shebang right now. Your idea is one I am considering!

    BTW, those marine fuel tanks are designed to withstand the rigors of vibration and rubbing and such because of what they are used for.
