Aluminum or plastic? What accessories? Fuel line, copper or aluminum? Have heard both are prone to cracking. Steel maybe? An idea, what do you think? I was thinking of cutting the sunken part of the trunk floor and flipping it over, welding it back with the hump up, mounting the FC under it. That way it would still be outside of the body. I don't feel comfortable with it mounted in the trunk.
Not sure what you application is (racing? daily driver? both?) My budget dictates plastic. Just run a ground wire from the metal part of the spout to the chassis (prevents static electricity) - plus, most tracks require it. Al would be nice - I'd rather spend the extra dough on go-fast parts.
Drag racing only Rick. I should have been more clear. Thinking of a 5 gal. cell. Thanks for your reply.
i think there are some specific rules in the nhra rulebook about fuel cells and their placement. i won't be able to look until tomorrow night. what i did on my 71 was take a cutting wheel and cut straight across the hump and then take a bfh and beat it down the other way. that way the sump is covered and also that is where the lines come out and go to the fuel pump. what problems do you think will happen in the trunk.
Well Don, my interior is gutted and has no bulkhead between the trunk and the other part of interior. In an accident I could become a crispy critter if the cell or tank ruptured. That's why I'd rather have it outside where the tank is now. With the trunk floor cut and turned upside down the cell wouldn't hang down and be so noticable.
fuel cell Put it in the trunk and put the metal divider plate in there. If it gets to the point that a fire happens, that'll be the least of your problems. If this is an electric fuel pump system, put a oil pressure switch and master cutoff in the driver's area. #8 Braided hose.
i agree. also if you put the battery in the trunk you'll have to put the divider in. just about every drag race car with a fuel cell has it in the trunk.
I believe a firewall is a MUST in classes on our level. I made mine out of aluminum. BTW, this was BEFORE I ran a ground strap (10 gage wire) from one of the acorn nuts to the chassis (straight above the spout) using a self-tapping screw (you might can see it in the attachment but you get the idea).
Thanks for all the good advice. I may wait on the fuel cell until I backhalf the car. Do all the metal work at one time. Thanks again. Jerry
Yes, Don. It's a 5 gal. Unfortunately, I guess the wire can't be seen in the attachment picture. It's just a 10 gauge jumper wire with "loop terminals" on each end. One end is secured to the spout using one of the acorn nuts and the other is attached to the chassis using a self-tapping screw. I'll try to get a better picture.
Jerry I use a plastic 5 gallon...I'd only spend the extra on aluminum if it was a show car...my fuel system requires a 10- an main line that splits at the regulator to 2, 6-an hoses... I have changed most of my hoses over to the crimped end fitting braided hose that Nascar use...I don't trust the reusable type 100%...here is an example of what I talking about... http://cgi.ebay.com/NASCAR-19-Goodr...111390QQihZ016QQcategoryZ107063QQcmdZViewItem
I've always used plastic. Aluminum is nice, but sometimes there is a chance of the aluminum corroding inside the cell (due to fuel additives) and it will clog a filter in a heartbeat...especially with alcohol. Braided lines all the way for me too, the regular kind. I ALWAYS pressure test the lines after assembling them with the ends and I usually test them at +100 psi. Never had one fail. I can't use anything but braided line or hydraulic line...fuel pressure is over 125 psi at the finish line. Idles at 20 +/-
