I moved on to other stuff...Now back on the TDM and guess what Studders it was as you said fuel going in via the vacum tube first occasion fuel went into engine but spotted that so did an oil change two more times and the intake valves were shut so lucky there had fuel leaking out of exhaust where it was pumping straight through so lucky that didnt go bang, but changed the diaphram pump for another all good at the mo,will put tank back on tomorrow.Top bannana Studders thanks. :good:
