Question: I have a mechanical Boost guage, autometer ultra lite marine pro comp. My boat no longer has a blower. Can i run a fuel line to the guage to montitor fuel pressure? It's the type of guage that measures vacuum and boost. Autometer does not make the guage i want anymore, which is a low psi mechanical fuel guage in that same face/trim. Rex Marine said autometer makes an electric fuel guage now, but i'd rather just run fuel to the boost guage if it will read properly. Thanks!
