My truck has 110,000 on it and I ran to home depot today and when I came
out, it was dead. Started fine at home. Normally when you turn the ignition
on you here the fuel pump whine, now there is nothing. So I am assuming it
is the pump assembly.
Anyone done one of these? I read somewhere that it is much easier to take
the bed off then drop the tamk. However, the 18mm bolts holding the bed
where put on by an impact and I don't have access to one currently in my
Tips, tricks, ideas?
Smack the bottom of the take with a short 2X4 and see if it starts. If it
does the pump is bad and will fail. You may be able to drive some of the
fuel out of it. Got about a week out of mine smacking the tank. I dropped
the tank, everyone told me it was easier to remove the bed, but I was able
to drop the tank with a piece of plywood and my floor jack. Getting the
hoses off the top of the tank was the only problem.
Al is right. My 98 Blazer did the same thing. The intank replacement was
really expensive too. I went with OEM but was made aware of some
aftermarket external pumps availabe afterwards that were quite a bit less
Get a friend or three and lift the bed off, you will be better off. That is
what I did.
Two people can lift off a short bed if they are fairly manly, otherwise four
people. It is not to heavy but awkward to carry. If you have big tires on
like I do, you can pop the wheels off and lower the truck down to so the bed
doesn't have to be lifted so high.
For the bolts, get a long extension and a big cheater bar. if you break them
off....they are 5 bucks each at GM.
If you do drop the tank, please get all the gas out first so when it lands
on your head, it won't break your neck.
Pulling the bed vs pulling the tank is something I face on some trucks.
For me pulling the bed safely is not a problem. I have a twin post, 4
arm frame pad style Lift. I can chain a bed to the lift arms and not
worry about losing control of it. Although I always have a second person
on hand to assist in this.
The reason most try pulling the bed is the fuel line connections to the
sending unit. On trucks with out the plastic canister connection
breaking the lines off is the fear. You can get the whole sending unit
if you think that will be a problem. I'm not sure which style a 98 full
It is best to drive out as much fuel as possible. Gasoline weights
roughly 6.5 pounds per gallon. The fuel tank it's self is heavy enough
when empty. If you remove the tank from the bottom, use a wood 4x4 or a
peace of of plywood to support the tank on a jack (suck as a 3 ton floor
jack) strapping the tank to the wood or jack is not a bad idea either.
I do this using a Transmission jack with the vehicle on my lift. Often
I strap the tank, or have someone hold it in place. I have had a few
tanks over the years fall. The weight is enough to divet concrete.
If your not accustom to dropping fuel tanks, try to have someone on
hand to help out.
