What you have to be leery of are the claimed Walbro pumps all over the internet, there are a lot of counterfits out there for a lot less money that I wouldn't trust.
One other thing to consider is that some of these Walbro pumps are not rated for ethanol fuels while some are.

This is correct. Genuine Walbro pumps are still good pumps. It's the counterfeit's you have to watch out for.
If you buy a frame mount pump from Holley, FiTech etc. it's likely got a china knock-off in it.
The old Walbro 255 which I run will not handle E85, but has been fine for me with the e10 stuff we have here in Colorado. I've got 7 years and about 30,000 miles of trouble free time on that pump. The only other consideration with that older pump is that you can not run it on PWM. Well, you can, but you'll burn it up quickly. It's designed to be run at near full steam at all times with a proper return line.
You have to step up to the 450 l/hr pump under part number F90000267 before you get a true E85 rated pump from Walbro. That said, the pumps you get from them today should be no issue with e10 fuels and should theoretically be fine for up to e15.
I can't prove it, but I'm pretty sure most of the gasoline that went through my car's tank this past summer was e15. The stuff didn't smell at all like gasoline.
And yes, for what it's worth Walbro who is TI Automotive supplies pumps for OEM's. The Hellcat pumps are made by TI Automotive.
