Those white handle pumps are known to leak. When I first joined here it was one of the most common mysteries. Everything seems to be fine but the engine won't start because the lift pump is leaking air.

Whether it is the cause of the shakes or not (probably not), you should still change that lift pump for a black pushbutton one.
