Need help with the 3.7L

20 years ago I had a 71 duster that I drove everyday 130 mi trip to work. ran great. sold it to mechanic friend, it kept having problem getting good fuel supply . he changed tanks 3 times. he finally found a dead bug in the long line from tank to pump, it would get caught at a curve in the line and plug it and and then work its way back from that curve and it would get enough fuel to run>LOL
