Do they have to be US Coast Guard Approved, too? I can't get the Merc replacement lines any more. Theses lines are 25 years old with 4 rebuilds/failures. I have a new cooler and was going to use 10an oil lines & maybe include an in-line oil stat + gauge. Hydraulic hose shop the answer?

Good. I'm replacing the hoses anyway, so I'll make it happen with 10AN plumbing & include a 215 degree in-line stat from Summit (Improved Racing)...wish it had a port for easy oil temp tap like Earl's, but I guess 180 degree is the only option for those. Anyone use these?

go with -12an.i believe you will be fine at 180 deg oil temp.
