I need a Volt meter! Having a jeep,its almost a Must have. I dont have a test light either. I did jump across 30 directly straight across & i did hear it click & then about 2 seconds later click again. Im assuming thats ON then Off hoepfully. ....I just went & bought a New Fuel pump & Screen. Dreading the installion though,but Im trying to Psych myself up to go out there & Do it! Any pointers anyone wants to share before I start? i know disconnect the battery,then disconnect the 3 wires from the pump & ground, then use a hammer to lightly bump the big metal ring COUNTER-clockwise & remove that. ....thats whare i will be learning as I go,so to speak.
