Hey all. After trolling through threads solv8ng my problem with tje vzj95 evades me..
Is there a breather for the main tank to assist filling and keep internal pressure at atmo??
Old tank was caved in by a mountain and THEN the previous owner fitted a rockguard on. Tank now replaced...

Oh and thought it was the flap and locked it open but doesnt explain the pressure when opening the cap...

How much pressure we talking? Should have a little bit otherwise you'll smell fuel all the time, they vent into the engine via charcoal canister

Luckily the cap doesn't shoot me in the face everytime I refill the auxiliary tank...and yeah, theres no fuel smell up front/ in the cabin either..

Oh and it still dies on right corners at 1/4 tank running 9n the main when some of the aux tank transfers??
Hmmm could be suction when I take the cap off but its ALOT...

There will be a breather, if you look in the filler where the cap is you'll probably
see its exit point into the filler tube.

If you have one tank and its spitting back then there is something wrong with
breather.
