Amazed with the difference in power

Has anyone tried the lift pumps off ebay? I called my local Dodge dealer a couple days ago and the lift pump costs $144.00 from them. From ebay I can purchase a lift pump for $49.00. What is the difference? Are Mopar parts that much higher than Delphi or any other brand? Thanks!

Regarding brands from ebay
Do they come with a pump, spacer, gaskets, and an advanced line?
If so, than you got a great deal.
I might buy one just for a spare.

Let me get this all absorbed.
Wanna, you have an electric Walbro fuel pump that has it's pressure end tee-ed into the fuel system between the mechanical pump and the injection pump, such that you can run on the mechanical, and flip on the electric at will??
Do you have a Walbro link??
Why the Walbro, and not the FASS??
Thanks.
I got most of the pieces from GDP http://www.glacierdieselpower.com/ , the rest came from McMaster-Carr.
The Walbro is a high pressure, high volume pump. It is putting all the fuel it can pump right to the injection pump, the excess is bled off via a bypass regulator. Fuel pressure ranges from 15 to 18 psi.
A FASS is an internally regulated setup, so the filter acts as a false load. You have your 15 psi up to the filter, after that the pressure depends on the restriction that the filter imposes - just like the factory setup. I would expect to be able to drag a FASS down the same way I can drag the piston pump down. That's not intended as a slam on the FASS, it's more of a slam on our puny filters. I see 7 psi drop through the extended filter with the Walbro - although that's with around 65 gph flowing through the filter.

I bought mine from ebay maybe 4 months ago. No problems yet. I got one of the ones that were going for like $49 that were surplus. Didn't come with lines or spacers or gaskets, had to go to the San Leandro Cummins for that stuff.
