fuel pump running all the time,good or bad??

Why not wire it to a relay to come on when the key is on?

When you say "all the time" do you mean even when the car is off? It could potentially run your battery down if you have it on even when the car is off, and there's not really any reason to have it on when the key is off.

Does it have a fuel return back to the tank for extra fuel? If not, that might be an issue as well if it's pumping fuel and it's not being used.
