Temp Gauge Issue

I recently replaced my cylinder heads with polished Offy's. I could not get the temp gauge out of the old heads so I had to cut it. I replaced it with a new aftermarket gauge from Mac's. It screws right in but I can easily push the line with the bulb far into the engine. Mac's says it's not the part but I can't figure out why it's happening. What keeps the bulb and line from going into the head and keeps the seal at the head?

Thanks.
 
You need the fitting that your fitting will screw into, the fitting and bulb will seat into that. The size thread going into the Ford head is 3/8" pipe. Stewart Warner used to have these fittings available as a separate purchase...

Thanks for the feedback. I can't understand why I need an adapter. I had a stock '35 gauge installed in my old Offy heads with no problem and the fitting on the after-market gauge screws right into the head. I'm not saying you're wrong, I'm just not gettin' it.
 
Ferndog, Karl is right. I had to find an adapter to hold my stock temp sender when installing on my Mercury heads. These adapters can be found at most parts houses. The stock head is built to seat the temp sender without adapter. This had me scratching my head too. Good luck!
