Depends on how bad it is as to if you will see the drops or not. One place the cracks like to start forming at are were the clamp is pinching down on the hose. Gas evaporates fairly quickly. If the fuel hoses have never been changed it would not hurt to do so, these hoses do have a limited life. GM never really intended to have 30+ year old cars still on the road, so they never really thought about this as a 10, 15, or 20 year maintenance schedule item. I've never had a fuel pump leak myself, but that doesn't say they can't. My experience with fuel pumps are they normally get stuck or just will not pump any more.71 Nova Dad said:Thanks...its a 307 which we put a new intake manifold and holley 570 carb on. Starts easily several days later. I will take a look at the fuel pump and the supply line. What am I looking for? Would I see drips? Also if a fuel pump is going bad are there any symptoms ie. poor mileage, acceleration etc.
