they're actually not that hard - there's usually just a couple of bolts
holding the straps in place (and on a relatively new vehicle, they won't be
seized by rust yet), tank lowers down, wires and hoses practically unplug
from the tank, hammer and brass drift remove the lock ring, and there ya
go.....the trick is to have the pump go out when the tank is empty.. ;-)
because a empty tank causes the pump to stop working from heat build
up. Fuel cools the pump, the more fuel the cooler your pump will
operate and the longer the pump will last. When your fuel tank is a
quarter full, consider that it is empty, otherwise you will be
replacing a lot of fuel pumps. Also when a tank is near empty the
fuel pump is picking up things that are better left in the tank and on
the side wall of a tank that is low on fuel builds scale. Threat your
pump like it was your heart if you like your truck. If you don't like
your truck then never put more than a gallon of fuel in it at a time.
That goes without saying.
I had a friend once with an older Olds '88 that wouldn't run for long when
he had less than half a tank. It'd do just fine with a full tank, but when
that pump got above the fuel level, it'd overheat and stop working. Took
him about 3 months to put 2 and 2 together and figure out that it only
happened when the tank was less than half full......
Just watch the hoses when taking them off...I have another brand of vehicle
(will not post it - this is a GM NG), and in order to take off the fuel
lines from the tank, it requires a special tool that slides inside of the
coupling to release it.
The tool only runs 3-4 dollars at one of the local auto parts stores.
Once you get the fuel lines off, it's a piece of cake (recently swapped out
for a new tank on the "other" vehicle).
Yes, typical for the Yukons and "Burbs" of 1997 nor sure of other years!
Have it R & R'ed from an authorized AC/ Delco shop. I had mine go out
within 6 months of it's replacement of the original and AC/Delco shop
warranted it, under the assumption its a Delco fuel pump! As in past post
advise, don't let the fuel tank get below 1/4, it cause the cheesy pumps to
heat up and burn out the crappy little electric motors!
I did my 88 S-10 myself. I got up in the morning and went to a parts store
when they opened, bought the pump, went home and dropped the tank and
replaced it, went inside and showered and then drove to work and made it
there before lunch time. You can loosen the bolts for the mounts enough that
the tank will drop down a little and then reach in and loosen all the hose
My guess is you might have a physical advantage over me. My big
hands/arms/belly are a hindrance to the process in this case. The tank came
out pretty well for me, getting the lock ring off the top was an adventure.
I should also add that in my change I also cleaned all bolts and nuts and
messed with my spare tire. Nonetheless, it was a really long and patience
