I think he means the ones coming off the oil metering pump on the side of the engine and going onto the 2 oil injectors on top of the housings and 2 oil injectors on the LIM.
 
I got a set of bits from Earls, and some of their AN3 braided covered line and made a set up for mine

with your recommendations this what i came up with.  please correct me if im wrong


OMP - 8mm banjo
2 x straight
2 x 45 degree - in line

rotor housings - 10mm banjo
2 x 30/45 degree

LIM - 10mm banjo
2 x straight or 20 degree in line



i looked at earls site and they didnt have any 8mm banjo ends.  was wondering if you can clear up what you meant by inline bends on your build post



thanks for any help you can give

sure - in Earls do banjos where the hose attachment is in the plane of the banjo, then they do about 3 angles 20, 35 and 45 I think.  They also do a curved 90 degree bend.  this brings the hose up at an angle from the banjo fitting.   The inline bends are where the hose fitting comes out in the plane of the banjo, but then turns at an angle on the flat.
 
I found the 8mm fittings (steel) on their brake section:

You can see that you what I mean about 20 degree fittings - they do these in both side and up forms.  You\'ll need to ring them for the 8mm fittings - as they need to get them from the US.
 
And this was the hose I used:
 
http://www.earls.co.uk/earls/hose/speedflex.html
 
I used the translucent blue one.  You have to trim just a bit of the plastic sheave - about 8-10mm from the end, and then a little of the braid - about 4mm before mating the banjo olive to the end.  Don\'t forget to put the heat shrink sleeving over the braided cable before putting the nut end on the banjo - and you\'ll know soon enough if you need to strip a little more outer plastic sleeve.  The trick was to trim the smallest amount possible - the heatshrink just makes it look neat once it\'s all tightened up.
 
Another tip - don\'t fully tighten the banjo fitting - test fit them on the car before tightening - then take them off and heatshrink them up.
 
I\'m reasonably pleased with the result and they will last so much longer than the thin and brittle standard ones.

I made my own using the old stock lines. I just removed all the banjo fittings, Purchased some high quality clear tubing and ear clamps and the rest is straight forward.
