rajul, I use the Slimline 2000 pump see link http://www.slimlineproducts.com/sl2000.asp

I use the black model that screws on the jug. I have pumped many gallons of fuel, I fly in AZ in the winter and WA in the summer so use it a lot. I knew the person who tested the prototype in AZ and was attracted to it then. When the owner of the Slimline gave a presentation on his new pump I purchased one at the local Hobbytown. I have never been sorry. I use a small 12 Volt battery about half the size of the flight box battery for powering the pump. It is virtually maintenance free so far. I like this pump better than the Hobbico as its more convenient to me. I dont use a control panel or flight box, just a tool box, radio box and fuel jug. My igniter is two drycell batteries on a Hobbico extension. ha. Your choice. Fix the old one you have and it will work great also.
