FPR install help...

Hey I got a aeromotive FPR and i'm not quite sure how it bolts on to the stock fuel rail on my 1990 5.0.....the old reg had the holes out on the sides and the screws went down through it, into the fuel rail itself..the holes on the aeromotive on actually like on the bottom of the reg...
whoever installed these know what im talking about...i got no other hardware with it except the reg itself...how do you put this thing on??? Thanks!

Also...i orderd a walbro fuel pump and i wanted to double check if its a 190?
i got all the kit stuff and on the bag it says 400-812 as a part number?
anybody?

ah im sending it back dude....
i ordered a kirban from jdsperformance and they sent me an aeromotive.....was gonna keep it for looks but im not risking it..i wanted the kirban cause they never leak and are a good part...i heard and read too many bad stories bout aeromotives...goodluck if ur keeping it....there are a few ethonal gas stations round here..and i dont feel like "remembering" not to put it in if i ever come to a station that has it...too risky when i put over 4 grand into my engine and then a 100 dollar piece of junk is gonna leak fuel and make the chance for explosion.
