I'm in need of the following parts for Vision Microsystems engine monitoring systems: VM-1000 DPU, oil & fuel pressure sensors, a VMS selector switch (does not matter which one), EPI-800 tach indicator, OAT probes. Will buy any or all of above and will consider complete used systems and "new in box" systems even better. Please email your inventory/pics/asking price to mooney37v@juno.com -- thank you and happy flying!
