Fuel tank pressure release

Is this normally done my the fuel filler cap? I hadnt thought about it until today and id rather not encourage the leaking.

On the ebay you get bike derived one way non return valves to take care of the venting £4.50 +p&p

Those arent suitable for fuel injection as I found out earlier in the year. You need something to let air in an out. Otherwise you build up a huge amount of pressure in the tank and the cheap ones then leak anyway.

You need a 2 way valve.

I ordered one direct from Newton Equipment.

You need one of these:

TPV8 is what I have. They are the best as they dont let fuel vapour escape either so you get rid of the smell of petrol in the garage too.

Not neccescelery

I used a fitting which screws into a flexible pipe and fitted it to the filler tube. Made by revotec.

Burton power sell them, search for 'revotec self sealing'

I only had 2 connections on the tank, one feed and one return, so decided to fit the breather into the filler neck.

Works fine, no probs to date

Just to say, I just have a short length of hose connected to the breather inlet, then the other ends tube loops down under the level of the back of the car
