GMC Motorhome, More FiTech progress

FiTech 23

With all the other crazyness with rear wheel bearings, riveted brake pads and all that we’ve still been able to keep moving on the FiTech fuel injection installation.  We are behind schedule… what’s new!  I’m scheduled to drive our coach “JayGee” to the GMC Sunshine Statesmen rally in the Keys next week…. the motor is apart but then Bill said he wanted the FiTech too… I mean what do I do, put his is or mine first……

In other words Bill is up on the lift (has custody of the operating table)FiTech 19 Both coaches have the intake pulled with crossovers blocked off  FiTech 15  FiTech 12 and ready for the FiTech install  FiTech 9 but see again, he has the lift, his tanks were out, frame covered with POR-15 rust protection and rubberized undercoating….. with NEW Timken rear wheel bearings!    FiTech 21 and the tanks replumbed to accept the fuel return, tie both tanks together at the bottom, pitch the fuel solenoid and do a proper permanent mount of the high pressure FI pump.  The venting will all stay the same… only the feed system will change to a single tank configuration.  Think of the second (front tank) as a 25 gallon fuel cooling accumulator tank feeding the main (rear) tank where the single pickup will be.  Anyway that’s all done on Bill’s coach too FiTech 20 so it looks like his will go in first.  So the fuel delivery system needs to be replumbed… you don’t want a 2 tank system behind a constant run single fuel injection supply system.  The FiTech computer controls pump operation… shutting it off when the motor stops (a great safety measure for an electric pump system).  You want a good return for the 125psi pump so we’ll use the pickup line going now in at the bottom of the front tank with it’s filter sock removed.  We have a 3/8 steel line connection at the drain plugs to tie the 2 tanks together under 1/4 tank inlet level.  The returned (hot) fuel will enter the front tank where it will cool off before making it’s way either throught the filler crossover or via the crossover connection at the bottoms of the tank.  Keeping the fuel cool is a real issue with Ethanol laced fuel.  The configuration will help with the fuel cooling at the same time offer a single path fuel delivery from both tanks.  Did any of that make sense?  I’ll go over it on Patreon later….

So with the underside done, Bill will get Jared building the FiTech system on the motor.  It’s rainy today, good thing all that outside work is done.  FiTech 16  OK gentlemen and Ladies.. strap in we’re going diver down into the wonderful world of the next generation of fuel injection… self learning…. 2 sensor set-up and fits under the floor…….. cheap enough to buy 2 and keep one on board to “plug-n-play” repair it if it ever fails.

The unit is mounted  FiTech 25We’re choosing to not integrate the ignition system…. “keep it simple”…… our original HEI distributer and ignition works very well AND anyone can fix it.. new is $195 and I want neither fuel or fire depending on eachother to work.  As in the old days… you have fuel… you have fire…. it works!  FiTech 24  This could be something I could get behind.  Our hope is to do a specific installation manual, video and kit on everything you will need to install the FiTech system yourself.  We will include all the hoses (making it all universal GMC fit), modify tips and parts to put his in your coach.  We’re changing the fuel delivery system and doing things to the intake too so I think this will be a great help…. Brother, we gotta do something!  Carbs and Ethanol do not mix well.  The definition of a carberator is ;;;; a controlled series of spring loaded air and fuel leaks!  Fair enough but if we could get our motors set up right…. there IS a better way…..stay tuned……

We have the original teal carpet in the Explored diesel out along with the smell soaked carpet pad  John diesel 4  now it’s time to pull up fiftymillion staples they put in on the pad…. that’s crazy!  Oh well, it’s handled……. stay tuned…

We have the diesels tires mounted, trued and balanced… here is my detail genius Arthur buffing up the shine on the Alcoa rims before installing them…. thanks man .

5.5.17 morning 1  I can’t believe we got that huge Onan generator working in that Revcon motorhome  5.4.17 morning 5  The wild thing is it has no starter!  It turns the AC producing section into a DC motor which spools the thing up then it switches over to crate AC power …. very WWII like5.5.17 morning 2  Good job there Danavan!   

Willie is settled in and we’re back on “Savoy Brown”, stay tuned for pics tomorrow……

Thanks for dropping by, please check out that now working 

www.lifeismorethanmpg.com web site.  Help us shape it into a neat place to go….. haven’t had time to do new videos over on Motorhome Rehab Ranch but there are like 20 or so of them… hope you’ve seen some of that mess.  And just thanks for the support. 

And as Buzz Lightyear says…  “to Infinity and beyond….”

 (((((((( o )))))))

Oh, one other thing… while he’s still with us, I wanted to introduce you to the guy who has been my best friend for the past so many years.  He’s been there for me through the good times, the bad and all that stuff in between we call our lives.  Danzig is our Mainecoon cat who was given to us to watch for a couple of weeks close more than decade or so ago.  2016-Danzid-2 over the years, he has grown to be the “stately gentleman” in the cat world in our neighborhood and completely taken our hearts.  All the other cats come up .. lay in the drive and just stare and commune with him.  It’s been one stable factor in my life…..  Well Danzig is not feeling well… he’s old, lost weight, doesn’t want to come in anymore and I’m afraid as all good things end… this awesome relationship may be there soon too.  Danzig 2017 2 So here’s to

  Danzig the Great 

……. everyone should have as good a friend  Danzig 2017 3Still a proud cat and my buddy, he will be missed.
