Incompatable hose ends and fittings

[Rick Parker]

I have been struggling with a leaking hose end/fitting connection for several months and am somewhat miffed at this point. The oil filter mount is mounted to the LH frame rail in a horizontal position and has black hard anodized -10 male nipples to which the straight hose ends attach. It is difficult to determine the exact area of the leakage, as it is hard to access without getting under the car . I have changed the piece of hose, chaneged the O rings on the ports that the nipples screw into, then eliminated the O rings and used aluminum crush washers to seal the nipples to the mount. Yesterday I was told that the hose ends I have (Auto Fit, from Earl's) are not compatable with the Prolite 350 Hose. There does seem to be some confusion on this point however, Earl's does indicate the hose ends as being compatable with the hose. I have good seals at all places other that at the location with the hard anodized nipples. I looked at the mating surface on the nipples and there is a small indention but no scribed circle on the surface that would indicate a good seal, and I have tightened them very well.

Anyone have a similar situation? I'm thinking I need to replace the hard anodized black fittings with something different???

Any Ideas????

Thanks
