  • Better price for Civic tank

    I have shopped around for a long time for a tank for my '98 Civic. I read through the entire thread concerning replacing Civic tanks. After that I found Optimum Composite Technologies in Brigham City. They quoted me $1959 for a 20-year type 3 tank, electric valve, 19" X 34". http://optimumct.com I started a new thread because I think this is too good to bury in another thread. It seems it would fit well. They'll sell it directly to me too! I'm on my way!

    OK, so I bought three of these tanks. They have a slightly larger diameter than the original, and are slightly shorter. I have installed one, it fits and works well. It requires that the bolts that connect the straps be about 2 inches longer than the originals, but it fits fine. A problem with any replacement, other than an exact replacement, is going to be covering the valve and connections with a bag or boot to vent micro-leakages. There is no provision for the valve to be entirely covered in a bag, which still could be done if there was the large metal disk installed between the valve and tank, like in the original. There is provision for the "in" and "out" connections to be vented. One of the original fittings can be used to connect the "fill" (larger diameter) line to the tank. Because two of the ports on the new valve are not the same size as on the original, one different-sized fitting must be found, plus one plug of that same size, since there are two identical PRD-relief ports. I'm pretty sure I could get the manufacturer to furnish the new fittings with the tank, so the effort won't have to be duplicated many times. The manufacturer gave me two PDF files for the valve. I'm not sure how to upload them here, but the valve can be seen here. http://johnsonbaby1.en.ec21.com/Auto...8_8404038.html I notice that there is a Chinese valve that looks identical, probably a copy. This valve is made in Italy.

    I didn't remove the old tank by taking out the frame and tank together, as the manufacturer suggests. I turned off the main valve above the left rear tire, ran the engine until it died, removed the back of the back seat, removed the back shelf, disconnected the lines and wires, removed the straps around the tank, and then rolled the tank into the back seat with some help. No I'm not a certified installer, but I am a certified redneck, I do all my own work.
