Next silly diesel question

[Swanrad2]

I have been reworking the MD11C in the boat for a while now. Big list of works done already, next task on the list is the fuel system. My mechanic friend has become unwell and left me in charge of the simple stuff for a bit - so I will be asking some daft questions, but the engine should be ready for him to inspect when he is well enough. Rest assured I won't be going to sea without somone good casting their eye over my work.

Between the diesel inlet on the engine and the primary diesel filter (about to be upgraded) is a black braided hose with what look like crimped on 'bayonet' style fittings. I photographed them and will try to upload, but for now my simple questions are:

1) what are they (based on simple description)?
2) where do I getaway new one (there appears to be an old repair using split Jose pipe and electricians tape!)?
3) before I start wrestling and cutting them off - how do they attach?

Thanks.

Awaiting photo but are you sure you mean bayonet fittings and not banjo fittings?

Thank you - what I assumed to be a braided hose crimped onto a metal fitting as part of the engine is indeed a Banjo fitting bolted onto the engine. Seems an easy replacement once you know! Do yo know of any good suppliers?

Take it to a local hydraulics shops such as Hyphose or Pirtek who will make one up for you.

Or just cut off the crimped fitting, remove the old hose, replace with new and use jubilee clips to secure the hose in place to the banjo union tails.

SSL Autoparts are as good as any but as suggested you may be able to re use the current one as described if on the low pressure side, if you do that then be sure to get new soft copper sealing washers or even better, Dowty washers to suit.

One point worth mentioning is that Pirtec et al are excellent at making up hoses with crimped connection but do not as a rule have BS7840 fuel hose so its worth getting some and taking it along with you.

Take the assembled pipe to a diesel specialist....Not a marine one....He will make a new assembly. Your Yellow Pages will tell you who.
