Installing a set of Dolphin aftermarket gauges. Came with a new sender for fuel tank, but doesn't have an integrated fuel pickup so I left the existing original one in place. Wired up the gauge, made sure good ground, etc. Full tank shows as 1/3 full. So I'm guessing sender is 0-30ohm and gauge is 0-90ohm. (History major, not engineer) If I am somehow right, how would I reconcile it?
