Barrus Fuel Tanks

burdenandy · 01 August 2013, 18:47

I have just acquired an Avon Searider 5.4M which has come with three 22ltr Barrus plastic fuel tanks (ex navy). Can anyone tell me if they are self venting or do you have to manually vent them when used, if so which screw is the vent?
Thanks

They should have a permanent vent in the cap. If they have screws in the caps, they may have been modified.

Thanks - I think the screws are actually fixings for securing a fuel line etc.

Make sure that the pick up pipes are in good condition

The vent should be in the black cap?

The brass insert nuts are for warning signs

Put 20 litres in and give them a shake, you will soon find out where the breather is, for such a well built tank the breather is a complete after thought.

I will say that they are one of the few tanks I've used that manage to use EVERY drop of petrol you put in.

I have a cap with the gauge and it leaks when the fuel is sloshing back and forth through the hole where the needle comes through, is that also the vent hole? Would anyone know where you can buy a replacement cap?

Yes, it's the vent hole.

The ones without a gauge leak the same as well
