Having spent the morning driving around Newcastle looking for a new olive, I discovered that B&Q do then as small as 8mm, halfords had no idea, a visit to my local bike shop yielded a 5mm steel olive for a hydraulic brake system. but nothing smaller or in brass,
This is not an automobile part. Halford's (or any automotive supplier) would be helpless. On the weekend,
your best bet would have been to contact a heating specialist on their emergency line.
You should also order the plug I suggested and get a compression fitting to splice a mid-line break. That
tube runs alongside the engine and when it gets loose, it often melts with the exhaust heat.
http://tinyurl.com/cv86azpThere is ONE foolproof way of keeping the system, (though I still cannot think of a good reason why you
would.) The plastic tube is doubly more dangerous than the earlier copper line was. It's advantage, of
course, was lower cost. However, copper corrodes, making an oil spill inevitable. With a copper line
emergency, you squeeze the line shut with pliars.
Your best course is to replace these tubes with braided Aeroquip fuel line. If you deal with a Morgan
supplier who sells Aeroquip to order, they will know exactly what you need and cut to size and put on the
right fittings.
