Fuel leak........Nothing is missing.........get a 1/2" NPT pipe plug and some dope and screw it in there. Or just replace the valve with a ball valve so you can more easily drain the water that will collect in the tank over time.
The correct grease gun is a bucket type with a long hose connected to a "giant buttonhead" coupler. You can use a smaller grease gun in a pinch, but it's easy to apply too much pressure to the seals and blow them with the small guns. The larger ones with a high volume pump give a little more "feel" when the roller is full and some have a bypass that should prevent blowing the seals. The correct grease is "track lube". Closest analog commonly available these days is 000 weight "corn head grease" available at any agricultural equipment dealer in 14 oz tubes. You probably can go to a lubricant/oil jobber and get it in bulk pails if you find a bucket type pump.
Thank you ccjersey. I have to order a button head coupler off the internet because I couldn't find one in my town. once again thanks!
