Adding a reserve tank

[tom26]

Hi

I am hoping for some advice please

I am wanting to install a reserve fuel tank (using a portable tank in addition to an inbuilt tank) but cannot work out how to have the option of switching fuel supply. The connector on the engine is not accessible, I can access the fuel line from the internal tank so was hoping to have something on that that I can connect/disconnect to switch between the two, ideally a y valve with a switch or two female connectors that I can switch between a male connector on the line going to the engine but despite lots of googling I cannot find a y connector nor a male connector I can attach to a hose

Does anyone have any ideas if this is possible?

Thank you

Tom

I added a quater turn valve and a T peace to shut the main tank off

I had one of these on the Ballistic.

Had a length of hose on it coupled to a fitting so I could use the aux tank in an emergency.

i bought a 1/4bsp brass tank connector and screwed it intio the outlet of the water removal filter instead of the barbed fitting ,i then fitted a tank connector to my fuel line , that now leaves me with a choice of running off internal tank,but always able to swap to the portable tank should i have issues .

I think a L port valve would allow two feeds in and one outlet and the position of the handle would determine which feed in was being used. The description suggests one feed in and two feeds out but I don't see an issue using it in the opposite sense.

You can then use hose tails to attach a hose.

I've attached a link but obviously I don't know the size of your system.

This will allow your fuel line to plug straight on if you screw it into your inboard tank or filter outlet .

Thats what I had on the Ballistic, with a 3 way tap as well.
The potential problem with just using that is that if the seals in it fail you're going to be letting air into your fuel line-hence the selectable tap as well

Thanks for all the help, it is appreciated and has identified a few potentials for me

Some of them appear to require me to have access to tanks which i do not have

I have access to the fuel pipe and the primer bulb but no acess to the tank from which the fuel pipe comes.

So i am hoping to have the existing fuel pipe and the fuel pipe from the external tank to both join the pipe up stream from the primer bulb of the existing pipe. I do not know if having two male connectors at the end of each pipe from the tanks and have having a female connector just up stream of the primer bulb will work. The other L and T shaped valves appear to be focussed on having one tank going to 2 engines which is the opposite of what i need but i fully realise i may not be understanding

Thank you for all the help

The link I sent you allows two pipes to connect over a fuel barb so you can run a single engine off one tank turn the handle and run off the other tank. If you connect before the primer bulb you only need one bulb

Why not Just carry extra Cans/Plastic Containers (as and WHEN you need them!) I.e you'll probably only want then on extended Cruises....(saving space and weight when NOT needed ) Ofcourse They must be well secured.
I strap them down to deck mounted Pad eyes... and a LARGE!! diameter Jiggle Syphon pipe?
Cheaper...easier and less "stuff" to go Pete Tong.
I can empty each 25lite can in around a minute.... don't wait till you run out!

.... I do have a 225litre under deck Tank!

Thanks, was not sure that this had the diameter needed but am going to give it a go, was also not sure how to connect rubber hose to it but will ask the shop for it.

I know i could carry spare fuel and often do this when on any longer trips but i am keen to have 2 sources of fuel, partly because of a current issue which i am trying to get fixed but also for peace of mind as fuel supply seems to be the most likely thing to go wrong once out there

Thanks to all for the help

there are different size taps. If you measure the pipe you have one of them will fit. They will sell you a screw in barb, basically a funnel with ridges on. Screw that into the tap, push the fuel pipe up the "funnel" over the ridges and secure with a stainless jubilee clip.
