Have you asked your ins company what their view is on rubber fuel lines?

Its questions like that to Insurance Co's that can lead to restrictive clauses and conditions by Insurance Co's looking for any way out of claims .......
Just needs some bright Underwriter to decide that he doesn't like 'rubber fuel lines' and soon all others follow.

Thank you very much.

Nobody got upset. From time to time in these forums there are people who make unsubstantiated claims about insurance companies. There's rarely any evidence provided to support these claims, so they are generally treated as scaremongering.

In your case, I'd have thought that most boat fires result in significant damage and that the markings on fuel hoses might not survive.

Were they claims, or were they in fact questions that no one was asking or were afraid to ask?

Will my boat burn differetnly to other boats?

No, insurance companies sometimes ask for a survey and no surveyor will have a problem with flexible fuel lines.

My point was more cutting into fixed lines, then just slipping (no swages) on some fuel hose (which was not to marine spec) then adding a rubber bulb (which again is not to marine spec) and saying it is just fine.
It seems weird to me that people will spend a fortune on a boat, then try and save tuppence to run it?

That's really not what you said, you objected to rubber hoses.
I'm not sure how you know what spec people are suggesting?

How does your insurer describe your fuel system requirements? Do you have the wording handy?

Maybe that is how you interpereted what I wrote?

Do you really think people were talking about correct marine spec fuel hose and bulb?
Do you think they even know there is a correct spec hose?

I reckon it may be time for you to walk away from this and go back into your box.

If people go to a chandlery, or a marine engine place, and ask to buy fuel hose, do you seriously think they'll be offered the choice of proper stuff or dodgy stuff?
 
Slightly at risk of being seen as a bit thick; I've fitted a new to me engine, and because I'd used a 'bulb primer' during the rebuild, a fitted it into the fuel line; not steel but plastic, and have felt it's a good thing without having the boat launched yet. There's also a fuel lift pump in the system, and the fuel tank's higher than the engine.
I'm reckoning that with both the bulb and the lift pump there's not going to be an issue anyway, but would I actually need either of them with the tank being higher than the engine?

Yes, you still need at least one of them, the fuel bulb is superior to the piddly lift pump lever.

Given that you have to FORCE the fuel through engines 'labyrinth' system ... I would be happy with what you did.

Does a facet pump allow free flow when not powered (i.e. can it be used solely to prime, and be normally left left switched off )?

Just Google facet 12v fuel pump.

I got mine a few years ago.
It does not affect things when not switched on.

I appreciate you were probably referring to the particular pump you bought, but I've subsequently found that some Facet pumps do not allow fuel through when switched off, while others do, so I'm just posting this to help any subsequent readers after this information.

I found the following on an American car/kart racing supplies site.

'I only need an electrical pump to prime my mechanical pump. Can I still pull fuel through a Facet pump when it is off?

It depends on the specific pump. Some Facet pumps are equipped with a positive shut-off valve (also known as an anti-siphon valve), which prevents fuel from being siphoned through the pump. None of the pumps in the Posi-Flo line have a positive shut-off valve, so any of those would be a safe bet for this type of installation.

If you also want to be able to run the car on the electrical pump, then you need to check your chosen pump.

Facet fuel pumps without a positive shut-off valve (fuel can be drawn through with the pump off)

Facet fuel pumps with a positive shut-off valve (fuel will not flow through with the pump off)'
