Angier --

 

I got my oil lines at Sacramento Sky Ranch -- primarily becauseof the great things I have heard about them from Brent Regan.  They are also 30% cheaper than the Aeroquip-recommended supply shop at the airport where I work every day.  It was defintitely worth calling Sky Ranch.

 

I have been working with an A&P to set up the firewall forward stuff.  This is all new to me and I want a professional to tell me what to do.  He tells me, I do much of the work myself and only pay him to do what I'm not comfortable doing.  If I spend 6 hours at his shop I typically pay for 3 hours of his time -- it works for both of us.  And when we're done, I'll know what to do.

 

Anyway, he helps me with the oil lines by reviewing the routing and heping to identify what bend radius I can get away with.  How much clearance I need fron adjacent hardware and things like that.

 

Sky Ranch sells me Stratoflex 124J with integral firesleeve for oil lines.  I buy Stratoflex 124 with orange firesleeve for the fuel lines.  (124 is different from 124J but both are teflon with stainless steel overbraid and are replaced "on condition" rather than by calendar time.  I think that Aeroquip 666 is the equivalent from the other guys.)

 

I use steel fittings on the equipment end of any flexible engine hose that moves on one end.  Only if both ends are stationary (like between gascolator and electric fuel pump, both of which are mounted to the firewall) will I use an aluminum fitting and a firesleeved hard line.  On the hard lines, if you flare one end, slide the firesleeve on, and then push it back a little you can flare the other end, rather than completing the hard line and putting on the next size larger firesleeve over the B-nuts.  It looks much better.  I have an A&P with the crimping tool put the bands on the firesleeve for me but I do all the rest.

 

I don't have Sky Ranch's phone number but a quick google search will get it for you.
