where can i find a cheap manometer......i looked on ebay, there are so many......one that was shown to me last week i saw on ebay for 150 bucks.....too rich for my blood right now, that's over a ton of coal, but in my quest for coal mileage, it's probably something i should own.......dammit i can get 22 mpg out of my modified lincoln town car......i'd like to go a month on 2 tons of coal lol
You must be looking at the wrong one, do a search Dwyer Mark II, model 25, They only run $20-$40 depending. New they are only around $30. I picked 2 used ones up for $20 (for me and a friend). Here are a few I just found http://search.ebay.com/search/search.dl ... %3D1&fgtp=
YOu can barrow the one that is going around on here to check your draft.
I've got a couple NOS Condar Draft Kits Model 4 - !, which I could make available. They read from -.1 to +.3 inches of water and MM of water. Mount on pipe, however "maybe" they could be tubed to a remote mounting (Instructions say, "they can be mounted remotely"). Let me know if interested.
Mine's also a model 25 Mark 2 Dwyer, hunted it down online. My "pilot tube" is a 4' piece of flexible copper tubing that I had leftover from an unrelated plumbing chore. It's a little bigger diameter than the tubing that comes in the kit, but after I worked it on, it makes a tight seal. Total price I think $25-30, plus the "pack-rat" part.
