I put a new sending unit in my Montego and the filter fell off as I was installing it. they sure don’t make them like they use too. I installed two of those plastic clear filters on it. one from the fuel line coming into the engine bay just before it goes into the fuel pump so that you can see any crap that might be coming from the gas tank. also put a second one on the fuel line going into the carb. I like the plastic clear filters better than the glass ones. cause a friend of mine had a glass one on his 49 Mercury and it exploded one night on his way to a show and the car caught fire,by the time the fire dept. got there it was half way gone. total lose. very nice Mercury gone cause of a cheap part. I took the glass one off of my Torino and have been using the clear plastic ones now for 15 years or more. I replace them every year peace of mind and cheap insurance for all my cars. I pick them up at the swap meets for two for $5 they cost close to that for one at the auto parts store. I even use smaller ones on my two lawn tractors. HAPPY NEW YEAR to EVERYONE have a Great & Healthy one IN 2020!!!!
