OK Thanks, this is a Nitro from scratch, last fired one up over 20 years ago!
So need fuel pump lots of tube, fuel can clunk, pipes etc, already have an Align starter and ordered the Gryphon CNC Slow speed pump (Uses starter wand for power).
Be aware if you go for this pump, and lucky I researched it, there is a High speed version that has less flow for use with the fast aircraft starters (Sullivan etc). Where as the LS version is for geared Align type starters, saves having another damn battery to think about
Another query:
I will use a T fitting to fill near the fuel filter feed to the carb.
Now then, the OS 105 has rear crankcase pressure, this has a check valve or non-return valve, so when filling the tank, I gather there is a need to create an air vent, say using a T fitting near the check valve?
