I am having a huge issue with my Gloria 100 pressurizing.. I pump it about 75X and it seems like not much air comes out... i have cleaned the check valve and everything..It has a new cap gasket..etc Please help..
@LanternTom Does the tank hold pressure? That is, after pumping 75 pumps, does air come out of the filler boss if you loosen the filler cap? Tony
@LanternTom I’ve just looked at my operating Gloria 100. With the fuel control valve closed shut, the tank should hold pressure with about 20 pumps, and escaping air should be heard through the burner when the valve is opened. You either have a blockage in the fuel system; the pump is not working; the NRV (pump valve) is not working; or there’s a leak somewhere. Cheers Tony
@LanternTom Tony will have good advice to follow. Strip your lantern down to just the fuel pick up so you can positively shut off the air. Your pump cup renew it or revive it. Your NRV once you have sorted out your pump cup try to put air into the tank. Dunk it in a bath of water and look for air bubbles. Air bubbles from fuel cap, renew seal. Remove pump, air coming from bottom of pump tube NRV needs attention. Turn on fuel valve no bubbles fuel feed tube in the tank, remove and clean very thoroughly. Check all these steps first I’ve restored a few of these lanterns. I hoe this helps
@LanternTom How are you going with your Gloria 100? I’m about to look at the NRV (pump valve) in one of mine if you’d like to see how it’s serviced. Best regards Tony
@LanternTom The NRV (pump valve) is a standard Primus-type stove set up: It has a slot for a wide screw driver; but it is also an 11mm (7/16”) hex. The original pip is most likely cork but I’ll use Viton to replace it. The spring is not hard. It’s quite flexible. The trick is to make sure the pip sits flat about 1mm above the cup, so that it makes a clean seal against the brass above it. The NRV is fitted with a lead washer. When removing the tube that covers the spring, cup and pip, use a drill chuck to hold the tube, rather than using a screw diver in the slot at the bottom of the tube. Cheers Tony
