A buddy of mine has a 62 pylmouth belv. couldn't find a float sending unit for a 62. and had to go with one out of a 65 and now his fuel guage only goes up to half full all the time when the tank get past half empty it starts to work. My question is can the restinces be off between the gauge and the sending unit? can a restistor be used to help or any ideas on this Thanks Bud
