Fuel pump question?
#22
Yup, crimp connectors and electrical tape should never be used on a vehicle... for anything... period. Always use 60/40 lead/tin rosin core solder and heat shrink tubing to waterproof the connection. Glad you got her figured out.

Actually though, speaking of corrosion, the fill tube assembly is really nasty looking. Where was the leak on yours, and did you find a good used one?

Fuel pump follow-up
The pump is in, and the truck runs fine. A couple of heads-up hints for anyone else who has the misfortune of their pump going bust:
First off, now that I know the exact position of the pump, connections and how much clearance there is, if I ever have to do another replacement I will start with an air chisel! There is plenty of room between the rear seat mountings and it is in a spot that would be very easy to fashion an access panel to close up after the job.
That said, if you do drop the tank you need to remove the bolt that holds the fill tubes to the cross-member. It makes it easier to refit the hoses when putting the tank back in place. That bolt is a real p***k! To remove it, I used a 5/16 X 1 1/2" bolt with a nut run on until about half of a nut thickness is showing through. Then I added another nut and snugged them together to lock. Using that set-up from below I was able to run the bolt back out of the frame. When I re-assembled, I used a 1/4 X 1 1/2" bolt and a lock nut. Much easier to get the 5/16 wrench in between those lines.
Like Raybz I got the parts from rockauto.com and I am mostly pleased with their service (especially the price, after finding a coupon code for 5% off the entire order) One thing that would have been a problem if I was in a hurry - I ordered the pump, a new filter and a new lock ring (old one was badly corroded). The pump and filter came via Fed-Ex the next day, but the ring took 3 days by mail!
Now the bad news.... I took a quick test drive this morning and when I stopped after a mile or so to check the connections there was a steady drip from the area under the driver's door. Came back home and lifted the truck enough to see what's dripping (fully expecting to find a bad connection on the filter), and found a nasty leak in the break line! So now it's off to that area of this site! Thanks to all who posted, and to those who took the time to read my rants without responding.

Xtreme 2002 Fuel pump
I got a fuel pump off ebay few days ago from a warehouse not to far from my home. Called around to auto zone, pep boys murrays, advance etc prices range from $ 320 - $350. I got mine for $57 bucks no one could believe it, when i removed my original pump I had no fuel gauge the pump made a loud sound when truck was running now after new pump its a slight wishper. All i can say is it pays to shop around.
#27
There's a reason for the difference in price Aftermarket pumps rarely meet GM factory spec requirements, so they don't last long in these vehicles, if you get one that works when you take it out of the box. Use AC Delco or Delphi only.

Went with the Delphi
I took the advice of the Captain and others who recommended using either Delco or Delphi. I got the Delphi pump, a new filter and a lock ring/o-ring kit and the price from rockauto was $240 w/shipping (after a 5% coupon). One more tip: If you buy the Delphi pump it comes with a new o-ring. I could have saved a couple of $$ if I knew that. Oh, about my last post....that's brake line, not break line, LOL. I must have had fluid in my eye!
