Walbro 255 fuel pump install pics
Posted: Sat Jul 11, 2009 10:06 pmInstalled on 2000 V6 Camaro
Walbro part number on summit racing-->Granatelli Motor Sports GM722-2 - Granatelli Motor Sports F-Body In-Tank Fuel Pumps
Well, me and dad, installed the new Walbro 255 fuel pump. Everything went ok. However as you will see in the pics below, one part of the casing did not fit onto the new pump. Still searching to see what the little black hose does, however, the new fuel pump does not have any vent area on the bottom or top like the old fuel pump did. The Walbro 255 does have a hole in the same place where the black hose hooks in to the old pump, but has not attachment that will allow the hose to hook there. Again, still searching for what that black hose does, or if anyone knows what the purpose of the black hose is, please let me know. I started the Camaro and it idles fine, plus drove it around the yard and up the drive way, everything seems A ok. Going to install the 36lb injectors tomorrow
Here are the pics of the fuel pump install, sorry I didn't get to take more, but after getting gas all over me an then finding the Walbro 255 had no place to hook the black hose, plus it was a pain to fit it into the stock casing, I kinda forgot to take more pics, was just glad to get everything hooked back up...
A little tip, when installing the new Walbro 255 in the stock casing, first install it fully in the rubber boot, then take some fuel system cleaner and wipe and wet the inside of the plastic casing, then the rubber boot, with the Walbro 255 will work, it will be a tight fit, but it will pop into place. The Walbro 255, is a little larger than the stock fuel pump.

Walbro 255 left, stock right, notice if the pic allows, the small hook-up on the stock pump on the right of the pump, the walbro 255 does not have this, to allow the small black hose to fit.

Casing with the black hose hooked up to the stock fuel pump, this is the hose that would not hook into the walbro 255, since it had no adapter for the hose to hook into.
Pic of casing, and where the black hose runs to.
