How long does this job take?

Do the pumps generally come with gaskets? I also read that it is good to replace the lock ring that can get rusted out.

Any other words of advice from those who have done this?

I had mine done by someone. It's not hard to do but I didn't feel like going through the trouble of dropping the tank and everything. The new assembly should come with all new gaskets and everything. As far as the lock ring goes if its not expensive for a new one I would get it just in case especially if you live up north or the vehicle spent a significant amount of time up there at one point.

I was going to replace fuel filter at same time. Do you need an SST to remove it?

Best off doing the whole sending unit. Mine came with a new connector for the pump as well. Make sure you use good weatherproof crimp connectors and a decent crimp tool for making the connections.

If you are doing it on jackstands it will be about 2.5 hours. Just make sure you run the tank empty before you do it. Spray all the fuel tank hanger hardware with penetrating oil 10 minutes before you remove them and take your time with the fuel line connections. Also don't kink or break any plastic lines.

Yes, the assembly comes with a new large o-ring type gasket. Tip: make sure you coat the whole o-ring with di-electric grease as it aids installation.

If you live in the rustbelt or where winters means salt on the roads then I would suggest the lock ring. Otherwise they hold up pretty well.

If there is a fuel filter, you should always replace it with a new pump. A clogged filter can cause the new pump to work too hard and shorten it's life dramatically while also giving you drivability issues such as lean conditions. No SST's needed for the filter. Just basic line wrenches.

Thanks Slchoe, that really helps. I should be receiving pump today, with lock ring, and will try to do the work next weekend.

Is there a write up in the FSM? i could not find it. I will look again on line for any write ups on some forums.
