So im about to install a tranny temp guage and was gonna use a block just like that. is there any problems with the fittings? any tips for cutting the lines ? do they need flared? i am able to do so if thats the case. I just dont want to be loosing my transmission when im trying to hel pit.anaheimxj said:I found the manifold to do it inline. its connectors look to be compression fittings that are screwed into the block. I have little faith in that type of fitting. I could replace them with flares, barb-type fot the flex/rubber hose, or the like without causing any reading problems, right?
