First of all I'd suggest that you get a specialist to look at it
however...

If you choose not to then start looking between the solinoid and tank
using 
soapy water to look for traces of bubbles. If that fails don't be shy of 
spa****ng whole bucket loads of soapy water around to try and locate any 
bubbles.

Ultimately its most likely to be a loose joint that needs sinching up on a

compression joint however also look for anywhere the pipes may have
chaffed 
on anything.. even cable ties which aren't my favoured securing method but

often seen on bodges.

Don't rule out the possibility that the soliniod is leaking either and 
allowing gas in to the rest of the system.
