musclcar,
It can be like a puzzle--- Go carb to unsecured fuel block ---get the fittings started in the carb and the block and then start to tighten each fitting a little at a time until they are tight.-----If you have to do any shifting for position ,you will have to back off on some or one of the fittings to give you play to secure fuel block.----You can use a light sealer on the threads(compatable for gasoline).-----If you don't tighten them flush to the seat they will leak,that's why tightening them a little at a time will give them a chance to seat properly---JoeG
