Assuming the regulator isn't a complete pos, that's a heck of a deal.
I had something similar come with the brawler carb kit I got from Speedway
(850 dp, drop base aircleaner, fuel log, pressure gauge)
Mine had a teflon hose between the fittings, (8AN, by the way) and the log fit a genuine holley 850 perfectly. But it didn't fit the Brawler it came with! For some reason the brawler had the bowl inlets spead, just a leetle bit wider than the old 4781. I had to have a longer line made. (I simply could not manage to get the braided stainless line i had into the crappy fittings i had!) JUST the line and fittings was $32.
Anyway, the log setup that came with the carb lists at Speedway for over $100. And hose and fittings have skyrocketed in price.
If you can make that work for your application, I'd go for it.
Hopefully it fits properly, and the regulator isn't garbage. Doesn't look like a standard holley regulator would fit.
