Have you ever had a duhhhhh moment. Well I did today after receiving my Bonaco fuel lines. 



I cannot believe that I spent as much time as I did messing around with the Vans aluminum fuel lines. I have no doubt that I have over 15 hours invested in those aluminum lines that are now residing in the trash can. The 42" Bonaco lines are a tad short if you run them exactly as Vans has it in the plans.



    I drilled a new 1" hole in the tunnel wall creating a more direct route, and they fit fine. The fit is fast and I have no doubt the they are much safer than the hard aluminum lines. The lines are very well made and the SS web is even covered with a thick plastic abrasion covering. For newbies getting into the tunnel area save hours of work and just order up these lines. Faster - safer - better. If you have any questions, e-mail me on this web site or call Brett at Bonaco.

I have replaced the lines to the fuel filter with the bonoco lines,Brett is great to work with and maintanance of the filter is easier.-Jim 728DD

As long as you remember that flexible lines require periodic replacement-every 5 years or so, hard lines do not.  Faster--yes, safer--no,  better-- that is a matters of opinion.  

  

 Not sure why it took 15 hours to do the brake lines.  If I remember I think I did mine early on (right after Chapter 2 when the fuselage was still opened up.  Took about 2 hours.  This may be better advice than going with more expensive flexible lines that require periodic maintenance.  YMMV.

Flexible lines lifetime depends on both the material they are constructed from and their environment. Engine hoses of convention rubber core with steel braiding are very life limited because of the engine heat and vibration. The same hose used for a brake line or wing to fuel selector line will have more like triple the engine hose life. Teflon core hoses have no life limit, just condition. Hard or flexible depends on the need to flex and the difficulty of installation. Hard aluminum lines that flex regularly will not last. So, it all depends.

Bonaco's are Teflon, correct?  I didn't want to take the time to get the

measurement and have aftermarket hoses made up while I was first

building, so I used some Aeroquip racing hose and put on my own

ends.   I figure I'll fly it for 5-8 years and then sometime along

that period I'll get motivated to yank the lines out and replace

them with Bonaco Teflon/SS braid lines because then I'll never

touch them again.  In that particular application, they would

basically never need replacement for the life of the plane.



Using flex lines was a very big no-brainer after fighting

with the aluminum lines, as far as I'm concerned.  There were

many bends in the aluminum lines that despite using a

good tubing bender left me worried that I was seeing some

sort of stress cracking in the aluminum.  I think maybe

they must have had a bad batch of tubing for a while

because there were definite differences in tubing over

a couple of various orders I placed....and I really just

don't think fuel lines is a place to screw around with

quality issues.  I'm actually planning to replace the lines

going forward of the fuel selector with Teflon when I do

the others, too...and just go teflon 100% of the fuel path

to the engine.

Amen Tim.......... especially on the stress cracking. Those lines have more bends than a pot of elbow macaroni. If you check those bends out with a magnifier they are pretty ugly. 



If I was going hard lines, I would put a 90 degree fitting where the lines exit the tunnel. Rah-Rah    Bonaco

"If I was going hard lines, I would put a 90 degree fitting where the lines exit the tunnel."



In point of fact, that is exactly how the newer -10's are now being built. Vans upgraded the whole fuel selector valve arrangement, and plumbing, a bit.

I think Van's has recognized the complexity of beding hard fuel lines from the tank to the selector. Some new fuselage recipients say 45 deg. bulkhead fittings are now included for the connection from the tank to the tunnel.  Having 45 deg bulkhead fittings in the tunnel greatly simplify tubing bends to the selector and also eliminate the need for flexible tubing.

   

 45 degree blukhead fittings are used because the left tank has to be plumed to the right side of the selector and vice versa.

No, they're now 90 deg fittings, because Vans also changed the selector valve geometry, so now left goes to left and right to right. A lot fewer, difficult bends.

Yes they are, -6 TeflonÂ® core stainless steel braid with a clear coating.

That's perfect. Maybe I'll speed up my swapout and just do it next time

I know I won't fly for 2 or 3 weeks...probably a few months away but

once they're swapped I'm done with them for life.

Tim,



When you get to that point, please feel free to give me a call and I shall do my best to make sure that the replacement lines you order will fit your build.

Just tell me (when the time comes), how you took your measurements. That is to say if they are be overall length or seat to seat. 



Regards,

Brett
