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".
Let’s assume that you are ordering a hose that is a 45/90.  The 45 would be “Fitting 1”  The 90 would be “Fitting 2”
Assume you are holding the fuel hose up in front of you.
Assume the “Fitting 1” is the fitting furthest away 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 it will delay the order of your hose.

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 SEE LINK HERE FOR HOSE MEASURING VIDEO
Flare to Flare Measurement
Measuring tip of the blue AN Fitting to tip of the Blue AN Fitting (most accurate measurement) gives you flare to flare.

The top example of measuring From fitting to fitting is the most accurate method.  The bottom three pictures are the method for measuring an existing hose.  However, please note That the tip of the blue flare is not going to be directly in the center of the AN nut.  It will bias toward the inside of the nut.  If you measure from the center of the nut to the center of the nut, this will yield a measurement per side of approximately 3/16” longer than you desire.
