This is a bit off topic as it's not directly Vette related but I'm sure the concept would translate should someone else find themselves in the same position. On my 240Z project car I've removed the mechanical fuel pump and put in a Carter electric. It works well as long as the pump stays wet. Problem is, when the car sits over night the fuel drains back into the tank and loses the prime. I think the obvious thing is the pump is questionable but it does work, plus I can see this as a potential problem later on even with a different pump. So I'm thinking my options are, 1) replace the pump, 2) put a small tank under the hood before the fuel pump to keep a fuel reserve or, 3) put a check valve in the fuel line.
I'm leaning now toward the check valve because I think that would be cheap and easy to do. What I'm thinking of is a simple tube with a ball slightly smaller than the tube. Put a hose barb on both ends but put a crimp in the tube so that the ball will seal in one barb but the crimp will prevent it from going to the other one. This would be easy and cheap to do, it wouldn't be all that bulky either. It could be mounted vertically so it's simply a gravity set device.
So my questions are: is there a better solution? If I do the check valve would it be better before the fuel pump or after?
