Heat it up with engine running for a while or use butane gas burner and if they do snap it's not the end of the world take the housing of and use a stud extractor

As sible88 above run the engine to warm it up is my favorite plus a splash of plus gas or similar easing oil.

I had to use a blow lamp on one of mine on the 72, I got lucky as it made a fuel line a bit crispy but it didnt catch fire
