Thanks, im thinking of either drilling like that or finding a 1/8" to 1/4" adapter somehow ( I take it that the stock sender is 1/4" bspt? ). Will the engine will run ok without that green sensor in place? what should i do with it if i replace it? can i just unplug its harness and let it hang? Also what is the other plug below it? ( white harness with 1 wire) can that be replaced? does anyone know what thread size that one is? maybe it will be easier to find..
