85 Rotary I'm intrested to see yours when your done if can post some pics. I always find it intresting to look at other peoples work to see if there is a better way of doing things. Also, you may have posted and I read over but are going to use a steel tank or plastic?

 

The tank is actually plastic. I'm in the process of building a cage out of 1" square steel tubing for the fuel cell to protect it. I'm covering the whole thing in .050" thick sheet metal. The whole assembly is going to be heavier than I wanted, but at least its going to be safe.

 

Ok, here is the "basket" for the fuel cell. Its pretty much finished, I've just gotta clean up the welds on the outside surfaces so the sheet metal will sit flat when I get it. Its heavier than I wanted, but most likely worth it cause the fuel cell will most likely be SCCA legal this way, not that it matters really. I won't be running the car in SCCA racing. The tubing is 1" square with a 1/8" thick wall. A little heavier than I wanted, but I got 28' of it for free, so I'm not complaining. Amazingly enough, It took over 20' to build this whole thing, with only about a foot of scrap.




And the welder that did it all. Pretty good welder IMO. I'm only an amature welder, and I learned to weld on this welder, so i know it pretty good. $600 welder new, got it used for $200 I think. 220V with 6 heat settings and variable wire feed.

 

Ok, here is the just about finished cage for the fuel cell. The cell itself is a tight fit, which is what I wanted. All I have to do now is clean up the welds a little more, put some seam sealer on all the seams and paint it. The whole assembly is much heavier than I would have liked. I would guess about 50lb. But nothing is going to hurt that fuel cell short of a 100mph collision.

The top is made of 3/4" angle iron. The whole thing has .035" thick sheet metal covering it.

 

Hate to bump a one year old thread, but did you ever finish this project?

 

It cost more then $400 CND for an FB tank? I dought that very much.
