I recevied a pump awhile ago from a friend, and was told that it was a walbro(which it did say on it) 255 out of his 85 GLHS, and did come out it running. I removed my fuel pump and broke the top of the sending unit. Unfortunately I had to buy another sending unit to sway the pump. Well the after market was very different inside. It had some return valve that dumped the fuel back into the cup. Need less to say I didnt like that so I cut it off and melted it closed to resemble the O.E. I put it all together with my super 60 computer, and ect. Went to purge the car to start it up and the fuel pressure would go no higher then 25psi. So, luckly I work for a parts retailer and warrentied the pump:thumb: So I have took off the kit cuz I know the stock(New) pump is just too risky. Now my questions is. Is there a pump that they make (fool proof installation. I dont want to have to go throw that again. FM says they do..but is there really diffent 255 walbros. I guess Im just afread of buying it and my having to take apart the sending unit and it not working. The cardon pump that I bought is made just like the O.E. pump that I took out in the begining.:shrug: Any body have info?
