Hi John,
You'll be running out of things to do soon...LOL
I see you have a join in your return line, just temporary?
Are you planning to vent your tank with an inline valve with the spare outlet on top of your tank or go or just take the pipe up high and then route it below your tank?
I don't know if you have done it yet but have you fitted your earth strap/wire from your tank to chassis.
Johno
