Yes, but get a high quality automotive one like an Autometer. There are two schools of thought as to where to mount them. Some say don't mount them on the dash area (they can malfunction and spray fuel). Some say it is okay. If you don't mount it on the dash or upper clamp area then you have to mount it out of sight under the tank, which you can only view of course while working on the bike with the tank up. Typically you don't need a fuel pressure gauge on a non-turbo bike. Your call though, just talk to some experts first.
