Club Homepage Forums Classified Ads Buy & Sell - Everything But Airplanes E.I. FP-5L Fuel Flow

I have a 'working when removed' fuel flow meter. Electronics International FP-5L with red transducer. I believe this transducer is for engines with a fuel pump. What's in the pics is what comes with it. I don't have the wiring harness out from the ring connector. I'm sure E.I. would sell you one or your installing mechanic can fabricate something to work around that somehow.

$300 includes shipping to lower 48.

DM me for info.

Thanks,
Russell

According to EI's documentation, this is not the correct transducer for our gravity-fed fuel systems - should be the gold one.

Matt is correct the Gold one is for gravity feed planes …. However

I encountered a 150 with a red one on it after some discussion it had been swapped from a gold one by another shop that said they called EI and had been told to swap it. So I called EI and they doubted someone had told them to swap it ….. This prompted me to ask what the danger was of using a Red one on our planes as the owner had no issues and was very diligent about tracking fuel with no discrepancies from what the unit said was used to what was really used.

After getting transferred to another tech I was told the difference had something to do with the impeller and how it spun or started to spin in the two units based on pressure. The end answer was the red one might have a very small error when fuel starts to flow and as the unit aged (years) it might get worse. I asked how much worse and he talked in terms of maybe .1 of a gallon total error over both tanks full to empty. At no time was the tech so alarmed or worried about the red one that he did not advise me that it needed to be replaced. In fact he said if it was working that it was fine to leave it.

The owner is still flying the red one … said his bladder could not take flying for that long.

Russell, I called EI to ask if they'll sell the back half of that harness - they said they could do that but it'd have to be a special order since there've been so many iterations of the instrument/harnesses over the years. They'll need the serial number of the unit to confirm the details of the build - can you please provide this?
