Fuel hose diameter

ADS · 25 January 2005, 15:52

Hi guys,

Just been doing a few winter jobs on my boat and have noticed the fuel hose connecting the tank to the engine needs replacing as its getting a bit perished. This one appears to be homemade though

and I have a feeling it is too narrow, cant have an ID (internal diameter) of much more than 6mm. What should it be for a 40HP?

They come in 5, 6, 8 and 10 mm ID, see:http://www.bosunsmate.co.uk/hose_bulbs.htm

Thanks in advance,
Alex

EDIT: Sorry JK I should have put this in the engine section

Alex, if you don't get a helpful reply here I would email Andy Clark at the website you have posted a link to. He is very knowledgeable and helpful.

Ok Louise, will give that a go, thanks for moving my post! Do you think you could give Tim M a hand moving his 3m RIB (see his post)!

Hmmm. That may take a little more thought and effort! I reckon your suggestion is spot on anyway!

That should be plenty but you may find 8mm (5/16") fittings easier to come by than 6mm.

As far as I`m aware you will only find correctly certified fuel hose in either 3/8" (8mm) or 5/16" (10mm) ID, easily.
For a 40hp Suzuki you should only require the 8mm

Thanks for your help guys the thing is the current hose isn't certified and says suitable for food standard or something on the side

Will pick some 8mm up tommorow.

Thanks again
