Jose,
Basic rule: anything is legal if the FAA has signed off on the change on a form 337. Be sure to check the paperwork. (Yeah, everything has exceptions, but this rule works fairly well, I think. It's legal because the FAA said it's legal.) It seems silly to me to have two electric fuel pumps on a gravity fed airplane. If the paperwork authorizes the doubling of the fuel pumps, I wouldn't let that keep me from buying the plane, but I'd look a bit extra carefully to see if they did anything else silly. I vaguely recall that the O-200 STC for Coupes does normally include an (one) electric fuel pump. In the basic configuration, with one fuel pump and the header tank giving gravity fed fuel to the engine, you just need to fly along glancing at the float gauge on the header tank every five minutes or so. If it goes down significantly from your full-tank reference mark, you have 45 minutes or more to land gracefully - that's 75 miles range. Be sure to join the forum - we've got a bunch of real mechanical experts, some with A&P/AI (though their advice on the forum is just advisory, not official). They can get you and you're A&P going the right direction.

I am looking at an Ercoupe that has NO engine driven fuel pump but two electric fuel pumps. The header tank is still present. Jose
