I’ve checked all my hoses closely and all are good so it makes no sense to change them at this point.  When that time comes I will certainly be changing them to the SS sheath type.  I have the mandrels and have made them myself in the past but if the cost isn’t outrageous I’ll probably have them made to save time and hassle.  I am, however, adding the gauges in the system under the right seat but this is strictly for ground-based trouble shooting.  I won’t be able to see them in flight but up there it really doesn’t matter what the pressure is doing.  Either the gear goes up & down or it doesn’t.  You can’t fix it in flight.  Thanks for your input Jack.
