I found a great company to use for shipping gas pumps. They are called "Forward Air Inc". The serve many of the larger airports, and even though it looks like they fly the cargo, most of it is by truck. You can check their website at
www.forwardair.com to check their locations near you. You will have to build a crate to put the pump in, and you will have to deliver it to their terminal. On the other end, the second party will have to pick it up at their terminal, they don't deliver to your door. The prices are great. I had a 400lbs, cast iron Wayne 800 delivered to Los Angeles from Virginia for about $200. Check it out, if they are close to you, I think you'll like them.
