Help me identify Walbro fuel pump
 

I have a Walbro fuel pump GSS307. Below that another number 16700-1. What size pump is this?


------------------
88 347, Twisted wedge heads,Comp Cams 224/230 cam, 1/4=10.718 @ 123.02 mph

If your not having any luck identifying this pump, you may want to give Walbro a call and see if they can help. Their automotive fuel systems company is located here in Conn. and the phone number is (203) 235-6180

Thanks Jaydee!
