I'm trying to install my Advanced Flight Systems fuel totalizer 

between the fuel controller and the distribution block.  The 

hoses are AN4 and the totalizer has #6 pipe fittings - so I 

think that should be AN816-4-6D.  Neither Spruce nor Wicks 

lists them - any leads on where I can get it ?

Maybe try http://www.bonacoinc.com.  They've done some hoses for me and 

stock some wacky fittings.

Thx, but unfortunately no go ...



Looks like an AN912-2D bushing combined with an AN816-4-4D 

nipple is the only way to go ...

 Gerry,

  I'm a bit confused by your question. By definition, an AN816 fitting is AN male tubing (flare) on one end and male pipe thread (NPT) on the other. You have an AN4 hose, so you need #4 tube fitting on one end. What do you mean by #6 pipe fitting? Pipe fitting is either 1/16", 1/8", 1/4", 3/8" or 1/2" NPT or NPT. Do you need 1/4" NPT or 3/8" NPT?

 PS, Why would a fuel line for an RV only be AN4?     [quote][b]

Charlie,

  

  Pretty sure Gerry's transducer has 1/4" NPT female  "ports" on it.

  

On an injected 360, despite the  fuel supply hose being a -6, the metered fuel line (servo to flow  divider) is just a -4...at least on every installation I've ever  seen.

Gerry, the best way to deal with this IMO is to make a 90 deg. fitting by welding a 1/8" NPT pipe nipple to a 1/4" NPT pipe nipple as shown in the attached image.  I occasionally fly this F1, it has the AFS system and the fuel flow readings are rock-solid.  The flow transducer was moved here from a different location in the center tunnel near the boost pump.  The flow transducer did not work well near the boost pump.  Note that a small bracket was made to support the flowscan transducer.

Dan,

 Exactly! #6 implies 3/8" in regards to AN tubing. However, 3/8" NPT is huge. My transducer is also 1/4" NPT. I figured that he was confusing definitions.

Thanks all for your comments - Dan is right about the fittings 

between the fuel controller and divider (thanks for the 

correcting the nomenclature Dan) the tubing is terminated with 

-4 flare fittings.  However, the transducer I have (a red brick 

about 1 1/2" cubed), I'm pretty sure has 3/8 NPT female pipe 

fittings (I need to double check this tonight when I get to the 

hangar).  I think the intent of the manufacturer of the 

transducer was that it would generally go between the high 

pressure side of the engine driven fuel pump and the fuel 

controller - that's a -6 size hose.  Hence the need to reduce 

the size from a -6 to a -4.



Hopefully I haven't been spinning everyone's wheels ... report 

back tomorrow.



Thanks all again.

Here's a picture of the transducer.  It does indeed have -6 

pipe fittings.  The fitting in the foreground is -4.  Phew, 

thought I was losing it.
