While reading in a Classic Performance Products Catalog, it said that the newer sender unit had a 90 ohm resistor and that the old sender was a 30 ohm resistor. Since I used the tank and sender unit from an 88 S-10 Blazer (fits well in the frame where the spare tire goes), I assumed the sender unit is a 90 ohm because my gauge will not work.  So here is the question. Where could I find a resistor to change the 90 ohm to 30 ohms to use my stock gauge, or do I buy the “30 ohm” sender unit from CPP and hope it works in the new tank? Thanks  | | |

The easiest is to buy a new sending unit. But, what happened to me is the sending unit still didn't fix the problem. I ended up sending both units to a gauge shop and had them recalibrated to make it work. Cost was under $50., so not to bad. Cecil........... | | |
