Bucking issues

Before I sent the car for work by SCU, the car had intermittent bucking issues. When I got the car back from Dave, the motor had everything new, sensors, plugs, wires, etc. All was well.

Today I went to get some parts and on the way back I noticed I had low fuel. The car started bucking and I said to myself "this thing is running on fumes I need a station ASAP!" I got to the station and filled up. Now it's bucking again. Was bucking every 30 seconds or so after the fill up for the 5 miles home. The only things I can think of. Air in the fuel system, or bad fuel pump. I can't really bleed it because of the gauge mounted to the port.

Anyone else experience something like this?
 
when you rev the engine does the fuel pressure go low, stay the same, or go up? by the sounds of what you have said so far i would think to look at the fuel pump.

also make sure you have no fuel leaks.
 
Tach is fine. There is a small leak I think at the pump. I smell gas sometimes when I walk by the rear wheel. No puddles though.
