the Walbro and many modern high volume pumps are about half the size of the factory denso.
however there is almost no way to tell if it is a genuine or a knockoff short of doing a volume test both static and under load. neither test is easy to do because who likes pumping gallons of gasoline between buckets and with fuel pressure regulators installed?
the newer Walbro units did say TI auto on them, for reference.
there is literally hundreds of fake vs genuine articles on the net, people have faked these pumps more than any other made. some of these simple checks might make you feel better about its genuine-ness though.
