Fuel pump for 1968 Olds 98?

Fuel pump has died and no gas going to the engine at all - so time to replace. Any experience or suggestion for best replacement? Thanks for any replies.

Did you make sure you have gas to the pump?

There is lots of gas in the tank, if that's what you mean. Need to check if lines clear.

Disconnect the line going to the pump and make sure there is fuel there.

+1.. A leak in the line before the pump will cause a no-flow problem.

You were just having a problem with your choke pull-off. Now you've gone from flooded to no fuel?

I was mistaken on the choke - had a mechanic friend look at it last night and he thought it's working properly. Problem started when the engine just cut out when idling. Made same sound as when you run out of gas. I thought it was because I left it on high idle, but now I'm quite sure it was because it stopped getting fuel. Last night while driving, conked out again in the middle of the road. Pushed to side, disconnected the fuel line to the carb, and no fuel there. Done with key on. So I'm pretty it's an issue of no fuel delivery - either because of problem with the fuel lines or fuel pump. Will check all lines before replacing fuel pump. Another dumb question - but I couldn't actually tell from the manual where the fuel pump is? I assume it's in the gas tank?

Front passenger side of the engine.

Eric - spoke with a few parts stores and the only fuel pumps available for this car are for the ones with A/C, which have an extra nozzle. Mine does not have A/C. Do you think I could use that pump and simply seal off the extra A/C nozzle? Thanks for all your advice.

Yes, you can use a fuel pump with a return line barb and block that outlet.

There should be no problem getting the non-return pumps, though.

If I were home now, I'd post a part number or a link to one, but I'm sure someone else can.

Thanks Eric. I actually just found one at Rock Auto, which was recommended in other strings on this great forum. Thanks!

Have you checked the fuel filter?

I'd speak with a few more before accepting this as the definitive answer. I replaced the fuel pump on my no-A/C '67 Delta 88 not too long ago, and I had no problem getting the correct pump.

Autozone shows availability of a two-line fuel pump for your car.

They also have the three-line version.

I'd get the first one above before buying the wrong one and having to cap an unneeded line.

Checked all the lines before buying a new fuel pump and line between tank and pump had leak and was spilling fuel and causing fuel pump to lose pressure. Replacing fuel line now and expect to have this all solved

Ah HA!

While you're under there, you may wish to plug the hose on one end and pressurize the steel line with compressed air, to be sure the line has no leaks.

It's still possible that the fuel pump could be weak, but that hose had to go, and now you can test the fuel pump the old fashioned way, by flooring it uphill on the highway.

Hopefully it was the only leak. Good job.

I hate to **** on your parade, but better you know now. If the gasline under there is rotted out, so are your brake lines. That's one place where you really don't want to wait until it fails to fix it.
