hi i have a 1993 t4 camper it is petrol\lpg the problem is when i remove the the fuel filler cap
a lot of back pressure blows out. the breather pipe is clear i have ckecked it the filler cap seems ok
can anyone tell me where this pressure is likely to be coming from . can something be back feeding
into the tank.this is not ur normal expansion due to warm weather

make sure its pressure - not suction.

common mistake.

when unlocked the cap blows off if its pressure!
