New fuel pump came from RockAuto today. Got it installed nice and quick, and she started up with no drama after cranking enough to fill the float bowl.
With the new pump I was able to lean it out half a turn on both barrels. So I’d say the old one wasn’t flowing as well as it should before it totally quit. Now there’s no stumbling during the transition from idle to mains. I love this little truck, I need to get it insured so I can drive it around these pretty empty roads.
