Trying to decide how to install the red cube to the AFP fuel system I have.  Engine came with fuel lines made up and looking to possibly cut existing line to make red cube fit.  Attached photos show cube strapped to where I'm thinking of placing it.  Questions I have:



1). Is this the best location considering the system and lines that I have?  



2). Is it enough to support red cube by adel clamps above and below cube and let those clamps be sole support?



3). Where can I send this fuel line to get new fittings attached?

That's not a bad location and it should work fine.

I'm not a big fan of that. I would recommend a bracket bolted where you are proposing putting the Adel clamp.

You can't. Those lines are made and then the fire sleeve is molded on, I'm pretty sure. Aircraft Spruce has a custom hose order form where you can specify length, ends, sizes, etc. I would replace the single line with 2 new lines for that location.

I would call Tom at TSFlightlines a call to see what options you may have regarding modifying your fuel lines,   If not possible, he's a great source to get new lines constructed.

Bonaco is another good source.

Even though I don't have the AFP fuel system, I had the folks at AFP do 

the hoses.



I went to their weekend fuel injection class just to get gain some 

knowledge about fuel injection systems in general.   Great people there. 

   I came away convinced to move my GRT (red cube equivalent) fuel meter 

from the tunnel to where you are putting yours.  It did make my fuel 

consumption numbers it dead nuts accurate.



Months after the class I gave them measurements and such and they 

provided 2 custom teflon hoses, with firesleeve, a needed AN fitting and 

1 foot of firesleeve to wrap the (red cube) with.  It cost $191.46 plus 

shipping.



They will provide any  consultation desired.  As I recall there is a AN 

fitting 'clocking' consideration with their fuel controllers so if you 

need to change the direction of the fitting coming out of their unit, 

you may want to chat with them.

Thanks guys, called Tom at TS Flightlines and he will add fittings to existing hose, just sent it to him.  One other thing--do I need to get a short section of  2" fire sleeve for the cube?

I don't think it's critical depending on how you have the unit mounted.  

I was just mimicking an install that I had seen pictured.



I managed to use only one Adel clamp on the upstream hose.  That 

combined with the hose and padded (red cube) gave me a secure mount and 

some vibration/heat protection.  My unit is actually mounted on the 

front of the engine block.  But I have an entirely different set of 

components than you are using.  Same idea though.

When I was at that stage I called the red cube's company.



They said.



1.  The closer to the spider the better.

2.  Straight connectors in and out.

3.  Preferred no hard direct connection to the engine for vibration.

4.  Preferred slight tip up of the exit to the entrance.



They also said that they were quite against the Van's tunnel recommendation.



I mounted mine at the front of the case on a piece of bent steel with a bit of spring to it and have had zero issues with it.

I made all my own lines, they are actually quite easy.... Aircraft spruce sells all the components.



Just a thought...

         There is only one thing that will prevent a mag from firing ....         a grounded P-lead.  Check the P-lead to make sure you didn't get         it caught between things like the firewall/engine mount when you         re-installed the engine. 

         Linn 	
       

       Well, actually I lied.  After completing the SB and rehanging the       engine, the first time I tried a start I got nothing.  It just       cranked.  It wasn't immediately obvious but neither mag was       firing!

       

       This is embarrassing because I consider myself a careful and       reasonably meticulous amateur mechanic but I'll share it  for       reflective purposes.

       

       Using a mirror and flashlight I examined the LH Mag which had not       been touched except to disconnect and reconnect the P-lead and the       shower of sparks line.  It turned out that I had a lock washer       jammed between the P-lead terminal and the case of the Mag that       was grounding the circuit.  After removing the washer and putting       a fresh washer under the terminal nut,   the engine       started.

       

       But a mag check indicated that the RH Mag wasn't firing!  Unlike       the LH Mag, this Mag had been removed to facilitate       removal/installation of the tach pickup that is screwed into the       side of it.  So before the first start, this Mag required pinning       and timing which was all completed without an apparent problem.

       

       Again using a mirror and a flashlight I examined the RH Mag and       discovered that I had put the P-lead terminal underneath the       insulating washer instead of on top.  Well that seems like it       might short the Mag.  So with better lighting I rewire the upside       down P-lead terminal and try again.  The RH Mag is still 'dead'.

       

       I should add that every step in this troubleshooting process is       followed by much reflection, usually overnight, and study of every       reference document available.  I have copies of magazine articles,       Light Plane Maintenance Newsletters, John Schwaner's Mag book, and       printouts of various posts.  Tim's informative mark-up of Slick's       timing instructions remains the go-to reference guide for Mag       timing.  Thanks Tim!

       

       I decide to just remove the P-lead from the Mag and let it run       naked and hot, then work forward from there.  Well, that didn't       work either.  I still had a 'dead' Mag.  I should add the the       engine started and ran just fine with only the LH Mag working.        Only a Mag check indicated that I had a dead Mag.

       

       I'm thinking, "Oh no, I may have over torqued the P-lead and       ruined the condenser or something else that is going to require       parts or a rebuild".  But I decide to remove the Mag, take it to       the bench, blanket it with brain waves and then very carefully go       back through the installation procedure.  I pin it, remove a set       of plugs, position the prop, install it with fresh gaskets and       time it.   This time I leave the P-lead disconnected and run it       naked and hot again.  SUCCESS!

       

       The good news is that it is now running perfectly and I got some       experience with running a hot mag through the checks.  The bad       news is that I have absolutely no idea what I had done wrong       initially.

       

       Test flight scheduled for later today.  

       

       Linn, you are a gentleman for being so discreet in pointing out       the obvious but evidently I'm immune to the obvious.  Thanks for       giving me a chance to reflect on my stumbles publicly.
