Angier, I had Sacramento Sky Ranch build my firewall forward oil and fuel lines to my specifications for length and fittings (oil cooler to and from engine and fuel from pump to carb. and pump to gascolator) for my early 235 in about '92 or '93. They have a Teflon inner with SS over braid and SS AN fittings and include an integral fire sleeve crimped into the back shell of the fittings. They came with a pressure test document (for pressures much higher than will be seen in service). For ease of installation, I opted for a mix of straight, 45 and 90 degree fittings where appropriate. I've had zero problems with these lines and highly recommend the folks at Sac. Sky Ranch. Delivery was as scheduled (couple of weeks)  - not cheap but what price peace of mind, particularly for these critical components?

No association with SSR other than as one very satisfied customer.
