1992 Blazer Tahoe LT Fuel Pump
 

First off, thank you for allowing me to join this group , sounds very helpful . I hope this is the proper place to post this . How do I know which fuel pump to purchase without removing tank first , Is it the small cartridge type that is about 5"long and about an inch wide , or the type that is kinda enclosed in a large plastic tube .
Thanks
