Hopefully a couple of #10 fittings arrive tomorrow so I can relocate the 10 micron filter & give the motor a cold start

if OK, will drain oil & refill with fresh oil
Ended up removing quite a bit of the EFI loom as bulk head grommet was missing

all done now, but a job I could of done without
Been doing some of the smaller jobs, never the less they all add up....
