so the filler cap might as well be bucketing out diesel! any fixes for this or can i fit a newer cap/ entry pipe job lot to the tank!?

im getting about 230/ 250 a tank in a 300tdi?? i dunno if this is good but i swear it used todo more!!!!

cheers
 
You can replace the whole metal neck down to the hose leading to the tank, not too difficult and cheap...but why is it coming back out...are you cornering on 2 wheels???? At a guess id say you're filling up too quick and a couple of litres are disappearing down the overflow...or theres corrosion/a hole in the filler neck or hose to the tank...

The overflow, you mean the breather pipe to let air from the top of the tank escape out into the filler neck? There should be NOWHERE for the diesel just to pour out, it should be sealed.
 
i have no idea why its coming back out!!! i dont drive fast, i cant!!! but theres obvious leakage, over filling the tank maybe?? i swear its only just started though!!

But i have realised im also under reading on the speedo and that will effect the milage read put wont it!!!
 
Go for a new cap first ( I need one as mine throws it out with just under 3/4 of a tank full ) .
but check your filler hose and pipework . also take up the pannel under the drivers seat and asee if the sender unit seal is leaking etc .
