I'd be happy to shoot a thermal image/video of the one-way valve once my installation is complete.
Thanks Ben this is appreciated
I do have a few other questions for you all before I start my installation:
1) What about the air bleeder valve on top of the heater? In my experiments with a bucket of water, it's sort of hard to get the hoses completely filled with water and bleed the air to get the fully-functioning water pump to go full blast. In descriptions of other people's installs, I don't recall the bleeder valve being mentioned at all! Is it accessible after the heater is installed on the plate in front of the radiator? (I'm planning to do mine similar to DonDakin and Sandange.) I think that getting all the air out of the hoses SHOULD be less of an issue when installed in the car as the heater will be LOWER than the coolant reservoir, which is where I will disconnect the hose and then make the connection from the heater with the one-way tee valve.
I installed it on the front plate upright - as you did on your test board and never had any problems with air pockets
2) How do you stop vacuum from forming in the fuel tank? Seems like people have used anything from recycled oil plastic bottles to go-kart or lawn mower fuel tanks. A good fuel tank design should have an easy to access cap on top, and be easy to see how much fuel is left. A clear plastic fuel tank would be good for seeing how much fuel is left. Small commercial tanks usually have a very small valve in the cap that lets in a little air as fuel is used up. This prevents vacuum from being created which would make the fuel pump work very hard. For people who have NOT used a little commercial tank, how do you deal with vacuum? Is your fuel pickup just through a loose hole that also lets in some air? Any concern then for evaporation, spills, etc?
I bought a go kart fuel tank and it has a shut off valve located on the bottom and a vented cap
3) What type of antifreeze to use? The stuff in my iMiEV looks BLUE! (No, I'm not confusing it with the washer fluid reservoir...) I don't think I've ever seen blue anti-freeze, all the stuff I've ever used is sort of orange, yellow, or nuclear green! I know that there are certain types of automotive fluids that are and are NOT compatible with each other. I just don't want to get the wrong stuff.
JoeS covered this - a good quality compatible anti freeze .
4) Hose sizes. The hoses on the back of the coolant reservoir look very SMALL compared to the hose that came with the fuel heater. I believe that on the installation that Sandange did (with the one-way tee valve) it appears that a small hose (the original from the back of the coolant reservoir?) was able to be stretched over the end of the tee. If possible, I would prefer NOT to have to mess with hose diameter adapters, but if I do, I'd like to have them ahead of time and handy.
Yes a lot of patience and hose stretching made it work for me.
be careful where you cut into the original hoses to install the valve - try and locate it where you can work and reach it easily. Also - I had to remove the drivers front wheel inner fender to feed the pies from the heater up to toward the reservoir made it a lot easier this way.
