Hose Measurement and Clocking
If you purchase a fuel hose from us that doesn’t have a straight fitting on at least one end, we need to know how you would like the fittings clocked in reference to each other.  For example, if you have two 90 degree fittings, we need to know in which orientation you would like them secured relative to each other.
Following is a textual description of the “clocking” and also a video.

Assume you are holding the fuel hose up in front of you.

Assume the fitting furthest away is facing with the opening facing up.

If the fitting closest to you has the opening facing up, it is assumed to be in the 12 o’clock position.  If it is facing right, it is the 3 o’clock position, if the opening is down, 6 o’clock, and if it is left it is in the 9 o’clock position.  We will have a selection of clocking angles from 1-12.  If you are purchasing one of these hoses, it is very important that you select a clocking angle, or we will email you to ensure we don’t build your hose until we are positive that it will fit correctly.  As always, please feel free to contact us at steve@aircraftspecialty.com with any questions that you may have.

We make hose measuring easy.  Measure from the very tip on one AN fitting to the tip of the other AN fitting in your aircraft.  We take care of the rest.  Remember that if your fittings are not lined up perfectly, your hose will need a little extra length to it.  This is also true when measuring for a 45 degree fitting…you need to account for the angle the fitting mates with the AN fitting.

Please contact us if you have any questions.
