Guys,
Was having a nightmare fuelling up my model last night. As soon as the main tank vented to fill the second tank all hell broke loose -leaks around fittings etc, creaks and groans of tanks....I checked and double checked the plumbing and couldn't work it out...so have been stripping the fuel system back more and more and more.....until the only option left was the felt clunk....still couldn't see it unti I removed the felt!!
Notice anything odd??

May I suggest you double check yours at installation time
Rgds,
