There is a screen on the bottom of fuel pump. Look in the tech tips section for "how to rebuild a fuel pump" and there are some good pictures of it. Depending on what you call surges, the gas will come in spurts as the diaphragm only has one "push" per revolution of camshaft. It should be a fairly healthy amount--maybe third to half a cup-- and about 4-5psi.
The upper part of the dual action pump is actually a vacuum booster and not connected to gas at all.
