Thanks for these forums!!! I installed my oil pressure unit with standard 1/8 brass plumbing tubes. Never thought about it cracking. I've jsut beensaved a future headache I'm sure! I'll order this adaptor right now! Thanks for the input.

is the correct adaptor........You may find them locally at auto store...
