Fuel hose specifications

[Avocet]

Hi all, I'm replacing Avocet's fuel lines this winter. They are some sort of rubber, covered in steel braid and this has rusted so the frayed remaining ends are chafing into the outer rubber covering. I have a vague notion that there is a specification that the RNLI look for in their "Sea Check" and / or the inland waterways Boat Safety Scheme. Any ideas what this might be? (it's a diesel engine, by the way). If anyone knows, I'd also be grateful for a supplier. If the stuff is sold "off a roll", I'll need a length so I can get all the individual lines made up and then I'll have to post the lines back to have the ends swaged back on - I've managed to salvage the end fittings off the old ones. Does anyone (ideally in the far North West) offer this service?

I got some from Halfords - they assured me that it was the right BS or EUD or whatever it is - its been on the boat for three years now with no sign of deterioration.

The hose you require is BS7840 if my memory serves me correct. ASAP supplies sell it. I deal with MEC components mail order he can make the pipes up for you with your original bits, he's really helpful and reliable, I can supply you with his details if you require.

You need ISO7840. ASAP sell it by length.

I bought some yesterday from INTERNATIONAL MARINE SUPPLIES in Gainsborough, Lincolnshire. Clips are double crimped variety, not circlips. (circlips have a sharp edge inside, which can cut into the pipe)

You can also get it in made up lengths in chandleries(Foxs in Ipswich have them), or you can get them made up by a specialist. There is someone who will make up to whatever you want who advertises in the back of PBO. I used them about 3 yeras ago and they were reasonable.

I was told that the steel braided line no longer complies with the latest safety regs and therefore is becoming difficult to obtain. (This was the guy at Peters in Chichester). The new alternative is a reinforced rubber tubing.

I don't know however I also have a section to replace where the braiding has completely rusted away. Seems a bit dumb to put a mild steel (albeit galvanised) braid in a saltwater environement. The question is, do I replace the lot or just the rotted section?

If you are keeping the boat I would replace the lot. Should be one less job to worry about for a few years.

I'm having to replace my fuel lines for BSC (BW boat safety certificate) One of the simpliest of setups. A small tank is resting in a wooden box inside the wheelhouse, with gravity feed. See photos of engine layout <A target="_blank" HREF=http://community.webshots.com/album/74722648AFxsmN>http://community.webshots.com/album/74722648AFxsmN</A>

You would have thought this would be simplisity itself....wrong. I've got to put the fuel filler outside, and the ISO7840 fuel line is very costly from my local supplier. They wanted £21.63 + VAT for ONE metre of 51mm pipe. I've already spent £30 for 3 metres of 10mm + a couple of unions, clips and a plastic breather.

It was going to cost close to £100 just to repipe to an engine almost alongside, and put the filler the other side of the plywood wheelhouse. Luckily I have a small tank I can modify and use, so in the end, all I should need are 5 metres of 8mm flexible (from ASAP) and a few clips, plus the breather, which can go in the cap.

I have just replaced the rusted line on my yacht. I had to dig (Rang Opal marine, visited Peters boatyard, and finally I found two companies who specialise in flexxible piping, both in Southsea / Portsmouth. They are :-

Hyphose Ltd
Unit 1, Trinity Ind Est Millbrook Rd West
Southampton Hampshire
SO15 0LA

Tel: 023 8051 2555

and

Pirtek (Portsmouth)
Unit H, Highgrove Industrial Park Quartremaine Rd
Portsmouth Hampshire
PO3 5QQ

Tel: 023 9266 6766

I went to Pirteck, and the guys were very helpful. Th ebraided line was replaced with rubber covered armoured line (braided) and they swanged the end fittings out whilst I waited. a 3m line plus fittings worked out at 55 pounds but the line could be bought for 12.97 per metre.

Very usefull place...

Good luck
