BadMooneyRising Posted November 4, 2023 Report Posted November 4, 2023 Hi folks, any recommendations for a replacement manifold pressure/fuel combo gauge? It’s for a 1974 F model. Found a couple shops for overhaul, but would prefer a swap.
PT20J Posted November 4, 2023 Report Posted November 4, 2023 It's a Mooney part so it's unlikely to find a new one unless some MSC has new old stock sitting on a shelf somewhere. Probably lots of used ones around removed from airplanes that have been upgraded to engine monitors. Have you tried eBay? However, if I were to buy a used one, I'd send it out to a shop to have it overhauled anyway. It's not that expensive and then I'd know it was accurate.
BadMooneyRising Posted November 4, 2023 Author Report Posted November 4, 2023 @PT20J Thanks. I did find this listing on eBay. Appears to be an identical part… https://www.ebay.com/itm/204507674527
Mooney-Shiner Posted November 4, 2023 Report Posted November 4, 2023 I took mine off from my 67F to install JPI900. You can have it for $300, if you'd like. If you don't like it, you can return it for full refund 1
PeteMc Posted November 4, 2023 Report Posted November 4, 2023 When my MP/FF gauge died I could not find a replacement and no one had the parts to rebuild mine. So I ultimately found Aerospace Logic (from a comment from someone here). They also have a MP/FP that you are looking for, but I don't know which of the ones on this page would be for your plane... https://www.aerospacelogic.com/engine-instruments/fuel-and-manifold-pressure/ BIG NOTE!!!! One big down side of Aerospace Logic is that for what ever reason they did not get their device certified with anything other than THEIR Transducer AND it can only be connected to their device (really dumb). So if you have a JPI or any other Fuel Monitor/Calculator this installation will require you to pull out the Transducer you've been been using and initially disable your fuel monitor. My mechanic added a big piece of fuel line to make sure there were no Fuel Flow issues and then did whatever test he needed to do to sign it off. So I got my JPI FF back, though the two don't match exactly. Need to fly from one Apt enough so that I can fuel the plane in the same level or unlevel spot to accurately measure how much fuel I'm burning. They're real close, but want to tweak them in even closer.
Rmfriday Posted November 5, 2023 Report Posted November 5, 2023 Looks like there is on on barnstormers https://www.barnstormers.com/classified-1802521-Mooney-manfuel-press-and-tbank.html not sure if it is for a carb or FI pressure range but it might be worth reaching out….
