This worked perfect, easy to install. I put a DVM on it and slowly moved the sender through full motion. No dead spots, very linear. I am excited to have a accurate fuel level again and at a great price!

Q: Why is there a right tank and a left tank version? How are they different?

Per the supplier: The 385C-F has what is referred to as a right hand swing to the float arm. If you hold the sender, mounting plate up, with the two holes that are closer together pointing towards your belly. The swing arm will swing to your right side. Do the same with part #385B-F and the swing arm will swing to your left. I hope this helps.

Q: I would like to know if the fuel level is interchangeable with the item 10-03419.

No, these items are not interchangeable.

Q: Would part number 10-01502 work with this for final installation in a fuel tank?

We have added a drawing to the documents tab for part 10-01502. Please review this file for specific compatibility.

Q: Will this ISS sender work with the Dynon Skyview?

Dynon recommends using Dynon probed with the Skyview system.

Q: What does the number 6-12 in PN 10-01099 mean?

It is referring to the size available. It can be used as a 6 inch or 12 inch depending on your tank.

Q: Part# 10-02079 indicates float only. Does this include the 12 rod that connects the float to the sender unit?

This is just the float only.

Q: Can they be mounted on the side of the fuel tank?

No, this is designed to be mounted to the top of the tank.
