So, I decided to try and use a 90 angle fitting in connecting this Mocal oil thermostat I have, but I'm a little worried about it having fitted it. The thing is, I've tightened both sides up, but the thing is extremely loose and has a lot of internal play that makes me worried about how well it can hold back oil pressure. Has anybody every used one of these fittings? I probably should have gone with metric to banjo fittings.
