My hose connecting the pump out fitting and the holding tank is original, 1987, to the boat. It looks a bit cracked and could be a source of oder. The current 2” ID hose is black with wire reinforced. Can it be replaced with a white pvc schedule 40 flex hose or does it need to be wire...

Quality T Tops in Tarpon Springs. They did 4 tanks for me, and 1 for each of 3 neighbors. Very pleased with their work.

Yes

Thank you all for the suggestions and help. After many tests and repeat test and even though I swapped senders to wire harnesses with presumably positive results, I swapped senders to motors and now the stb side works and the port side does not. Original stb side sender is faulty. Now to find one.

Yes all of the power wires from the ignition and all of the ground wires are linked

Are you available tomorrow Thursday? I have run a fee more tests today and still no joy!! I am in Gulf Harbors.

More thought needed since the stb sender works using the port wire harness and the port sender makes no difference to the stb gauge. It still pegs.

Using a lighted circuit tester, I connected one end to the ignition wire and the probe end to the wire coming from the sender. The light did not light. However when I touched the probe to a ground it lit. When I connect my stb sender to the port engine wire harness, run my stb engine, and turn...

Thanks. I am going to try one more thing tomorrow and will get with you thru TF

My sending units only have two wires. A numbered black which is connected to the gauge on the dash and a green which is connected to the low pressure alarm switch. If they are grounded it must be by the threaded fitting that attached then to the engine block.

New info as I do have Cat 3208s. Thanks. However wouldn’t all the gauges act the same way and max out or would it be just the engine oil and trans oil pressure gauges? I will check this tomorrow.

My panel hinges forward so the back of the gauges are accessible without removal.

I have run new temporary wires from the sender to the gauge and it still goes to max. When I disconnect the ground from the gauge it stays at zero when the ignition is turned on. With the power line disconnected from the gauge it stays at zero. They are all 1987 VDO gauges.

The issue is not too high pressure as tested when I switched wiring from starboard sender to port gauge and the gauge read proper. The gauges max when the ignition is turned on and remains maxed when the engine is stated and run.

They used to work for years then one day they stopped. As Soon as the ignition is on they max out and when the engine is started and run they remain maxed out.
