KR> broken fuel line and lessons learned
Hi Larry The PMA nipple where that line attaches to the engine block should have a very small orifice (pin holes size) to minimise oil loss in the event of a breakage you describe. The theory is that the pressure, being equal in a system, is still transmitted. Trouble is when the oil is cold this can take some time and your gauge is slow to register on start up when you really want to know quickly that pressure is there. Sometimes a light machine oil is put in the tube after the hole and provided it can't run out, that is, the tube goes downhill to the gauge, the time lag can be reduced. Sometimes the orifice nipple is mistakenly replaced with a normal nipple and then oil just pisses out.. head for the nearest strip quick :-).

If I'm not mistaken I think I remember similar fuel pressure lines in some of the other factory planes I have owned! I might be mistaken about the fuel lines though. > Larry H > ___ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.

> Hi All, Today Aircraft Spruce notified me that they no longer carry their 1/8" thick 4" by 2.5" 6061-T6 aluminum angle, and Wicks has nothing in those width/length dimensions thinner than 1/4". I've made several calls to metal suppliers and also local machine shops and they told me I probably won't find extruded angle in those dimensions. I have plenty of 1/8" thick 6061 plate but as per plans I would of course prefer to use extruded angle for the controls. Has anyone used a brake to bend their control brackets? Any suggestions or leads on where I can find extruded angle? Thanks, Seth

I just put on the new hose and I did use a small orifice in the fitting. Vans sells one with a .040" orifice for both oil and fuel pressure use. It is just a modified AN fitting with an aluminum plug with a small hole in it. I just finished making one on my lathe. For fuel pressure it is still very fast reacting.
