67 fuel sender

Any idea where I can buy a new one of these all the pictures at classics looks like the kind that is not a cylinder. I don’t think the cylinder comes apart.

Thanks for the help



My bad putting this in steering, I didn't realize the category before posting.

That cylinder is an in-tank electric fuel pump commonly used with factory EFI. What year is the car that it is out of?

67 fuel sender

1967 Impala SS, had a 327 with a 4 spd with a 2 barrel carb not original to the car. I wouldn’t be surprised if they just changed parts from other cars.

There was a mechanical fuel pump on the 327 I pulled.

Are there extra wires on the unit (other than the sending wire and ground)? Did the PO keep the pump in there but disconnect it and use the mechanical pump instead?

I see just the one wire on top that goes to the gauge and then a ground on the tank to the frame.

I have changed many fuel senders on 68 Impala's. What you have there is an original fuel gauge sender, they are not made like that anymore.
You have two choices, have the original one rebuilt or opt to buy the newer style with the metal arm. To have the original one rebuilt is between $125-$250.
The new style is about 50 bucks.
Good luck

tberg is correct. That is an original fuel sender. Not a pump.
As far as I know, canister style senders are not available. The canister design acts as a baffle so your fuel gage doesn't bounce all over with sloshing in the tank.
I believe later tanks have internal baffles to prevent sloshing and those tanks are equipped with the lever and float style of sender.
Your canister sender is a very simple device and may be repaired. Mine was suffering from deposits on the resistor elements and I was able to fix it myself. Be aware they have fragile parts inside and can be broken beyond repair if one is hamfisted.

Did you test your gage to isolate the problem to the sender?

This is my first post on this forum, but you can PM me for more detail.

I haven’t even tested it yet just changing the the tank and figured put in a new one. I can try it first with the new tank and if it works or just go with the new style.

Not trying to stay original so $50 isn’t bad.

Thanks for all the info.

If you have a ohm meter, its easy to test. Get a can or container slightly larger in diameter and deep enough to bury the canister.

Connect your ohm meter across the leads to the sender.

Pour some gas into your container with the canister in it. Watch the resistance change. If so, it works. You can lift the canister up and down out of the gas to test it. Somewhere I have the actual resistance values you can expect, bu if you see change you should be OK. I seem to recall 80 or 90 ohms, but I can't guarantee that.
