Inline fuel valve

[al40]

Does anyone know a source of small inline 1/4 turn valves that are suitable for use with petrol and are saltwater proof?

I want to add a splitter to my main fuel hose so I can route fuel to main engine or Aux. Unfortunately they have different connectors so I can't just switch the hose from one to the other. It seemed sensible to be able to isolate fuel from whatever engine was not being used. I know I could just unplug hose from engine not in use but that relies on the fuel connector being absolutely airtight and gives much more chance of water getting into the fuel if it's being plugged on and off.

Something like below claims to be suitable for oil but I guess that's heating oil and not petrol but this is the kind of thing I'm looking for.

This will give you - fuel off , fuel to main or fuel to aux

A nice cheap option for you:-

Put a T-piece in the fuel line. Add an inline plastic lawnmower tap. It's not like your aux is going to have problems getting enough fuel through one unless it's over 25hp. If it can survive being used by a gardener it'll survive most things.

BTW have a look at the price of the fuel conditioner. It's on the same page.

Great thanks for all your replies. Lots of options to investigate!

What do most people do with fuel supply for Aux? Seperate tank or run of the main tank (main tank in my case being underdeck)

I like the idea of both - ie if fuel in main tank gets contaminated causing main engine problem then at least there is a complete backup with seperate tank. If on the other hand the main engine fails for reason other than fuel then running aux from main tank is a lot more convenient!

[Nos4r2]

I've always used a seperate tank with the same fittings as the main tank-that way you've got a reserve too.
Either that or the aux has had it's own internal tank and I've carried a can full with me and a screwdriver to remove the main fuel coupling so I can decant from the main tank to the can in emergency.

Agree with Nos - keep your options open.
If your aux is only required for emergency back-up power, then I'd be inclined to have a separate source of fuel for it. Perhaps a 3 gal plastic tank will do the job?
If, on the other hand, you intend to use it more for everyday low speed stuff, you'll probably prefer to run it off the main tank with a T piece or changeover valve in the fuel line.
Carrying spare fuel on board is a bit of a PITA when you already have a large underdeck tank, but if your main fuel supply becomes contaminated, will the integral/separate tank of your aux have enough capacity to get you home?

You can get changeover valves from Pirtek, ASAP Supplies, Aquafax, etc.
