Centroid fuel sending unit.

I am having trouble getting in touch with the people at Centroid in
Florida. I have a bad sending unit and just can't seem to be able to
contact them. I could use help with some phone numbers or a way to
contact them. Have been calling since last Tuesday.

1) Hope to see you around a lot.
2) what kind of rig do you have? You can put your coach info into a "signature" by clicking on User CP (control panel?) and filling in the info. Folks get a better ideal of how to respond based on rig-specific experience.
3) Many RV's can use a generic sending unit that registers 240 ohms full and 30 ohms empty, like this one or this one. Mine rig has a side mount, for example, and the first linked sender can be installed sideways; I have to reverse the leads from the OEM positions so that 240 ohms is "float-up" position to read full. This avoids a $175 rebuild charge by the tank mfgr for their OEM sender and the 3 week delay inherent in a coach w/a large hole in the side of the fuel tank.
4) For anyone who doesn't know if their sender is the generic 240/30 type, and yours is working now, you can pull the two wire leads & measure ohms across them, match to fuel tank reading & see if yours is generic. 3/4 scale on gauge = 0.75 x (240 - 30) = 157 ohms more or less. If yours is only a one wire sender, then ground is the tank itself so red ohm meter lead on the sender wire connector & black lead on ground anywhere will read the sender ohms.

Thanks for the invite. I have a solid aluminum rod, that is straight.
It is rated 0/90 ohms. Made by Centroid for my Holiday Rambler40 foot motor home. I was just wondering if there was another number for them in Florida.
