Hey all

 

I started to fabricate the fuel lines in the tunnel etc today and where I attached the line to the firewall, I recently bought a AN832 steel bulkhead fitting (straight) instead of an AN837 bulkhead fitting (45 degree).  For those that have installed the fuel line to the engine, can I get away with the straight fitting or should I return it for the 45 degree fitting?  I intend to mount the fuel flow transducer under the engine (if that helps).

  

Thx,  Rick

You should be OK but it might mean getting something other than the

hose provided by Vans (Bonaco could make one).  You can get a custom

hose with a 45* or 90* fitting built in to the end.  You did good by

changing the provided aluminum fitting to steel.

The reason for the 45 degree fitting or 45 degree hose end is because 

the engine mount and nose gear isolators are right to the left of and in 

front of that fitting.  The angle allows the hose to loop out and around 

the engine mount and isolators before heading on its way to the engine 

driven fuel pump.

Also, take a look at www.kitplanehoses.com.

We have online pricing so you can "build" and order you hose directly from our website.  Our hoses are all conductive Teflon with stainless ends.  And, they are a true 37degree aviation flare.

If you have any questions, please go to

Www.kitplanehoses.com or email us at

Steve(at)aircraftspecialty.com

Have a great evening

Sean/Dave, thx for the info.  I'm heading to Aircraft Spruce today and will take the straight fitting with me and see if they will exchange it.  For the record, I did not buy Vans engine hoses, so the custom hose option is still open.

 

Regards,  Rick

Aha, thx.  I got to Aircraft Spruce (at) CYFD yesterday and switched the fitting I had for the 45 degree one.  Glad I did by the looks of your photo. 

 

So the fuel route is fuel pump, transducer, distribution spyder, cylinders?  Not sure thats correct?

Rick,

The routing is

engine driven fuel pump--fuel servo--FF transducer--spider--cylinders

firewall, fuel pump, servo, distributor, injectors. You can insert the transducer either between the pump and servo, or between the servo and the distributor. EI, who makes the transducer has it between the pump and the servo on their STC for certified planes, but several folks here have had success between servo and distributor, which is normal location for Continental fuel injection with fuel return line, that Bendix FI does not have.
