914-6 Oil line fittings, What Degree fitting where? Options

[Kerrys914]

I have AN-12 fittings at the four connection points for the two hoses.

What degree fittings are needed at each connection? I am going to buy the fittings and hose to make my own hoses. I will need to test fit the engine to get the correct length of each hose.

IIRC
- 0 Deg for the lower tank
- 45 Deg for the Upper tank
- 90 For the engine block
- 45 Deg for the oil cooler (I have a AN-12 90 Deg welded to the OEM cooler)


Cheers and any sources for the above would be cool too (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)

Will a 48" piece work for the higher pressure side?

i can't really help you on lengths, other than my approach is to get a too-long piece and cut to fit...

but just to clarify -- neither of the oil lines sees anything like gallery pressure - there is no "high pressure side"

the inlet to the pressure pump can see some suction, but the outlet from the engine to the tank is scavenge oil and doesn't (typically) see ultra high pressures. it does have a lot of entrained air, which can cause some shock as the bubbles compress, but there isn't really anything in the circuit to raise the pressure - with the possible exception of trying to run a front cooler with no thermostat. trying to force thick, cold oil through a cooler can produce excessive pressure. otherwise, the scavenge pump is simply a transfer pump, running foamy oil up from the engine through the filter to the tank for de-aeration and collection.
