Just had a chevy 1500 here 2004 model... holy smokes metal fuel pump with metal lock ring in plastic tank. I have never seen one rusted that badly
First off clean up all the dirt and debris, for me it took compressed air followed by a hand brush and plenty of PB blaster, I mean there was so much crud built up I didnt even know there was a lock ring for the first few days of soaking...finally got all the mud and rust out of the way so we could see what we were dealing with. All fittings on the stock pump just snapped right off, rust...dang chevy? metal on metal with some metal right where the tire kicks up road goo... it was a mess.
Anyways the key was to clean the area (just like they said) and then SOAK IT in oil, blaster, atf, anything to help get some lubrication in there, let it sit! clean the area some more.. and then use a drift and hammer. nothing metal on metal as a spark when working on a fuel tank is not a good thing (just like these guys said)
I like PB blaster myself, it seems to work really well as a cleaner and lubricant, penetrating oil, etc
In my 88 BII after dropping the tank about 10 times (have owned the truck a long time) I finally cut a hole in the floor and made an access panel... now I can reach my fuel pump in minutes not hours
