Phantom Posted May 12, 2015 Share Posted May 12, 2015 (edited) Thanks Keith. My original plan was fuel cell but i don't like the filler option inside the driver/pass space. No need for a chute as I can't run the 1/4 to save my life lol. Strictly a road racer/autoX/mountain/spirited weekend guy. Since the Z is unibody, I worry a touch about removing the wheel well and properly supporting again with big costs..... Figure if I sump the stock tank I can always change my mind later. Thanks again. Jim Jim, My son put a 16 gallon fuel cell in place of his spare tire well and ran the filler neck out behind the license plate on his '73 240Z. It's a nice installation. If you're interested I'll see if he can give me the MFG/model number. Edited May 13, 2015 by Phantom Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted May 13, 2015 Author Share Posted May 13, 2015 Jim, My son put a 17 gallon fuel cell in place of his spare tire well and ran the filler neck out behind the license plate on his '73 240Z. It's a nice installation. If you're interested I'll see if he can give me the MFG/model number. That would be great.... I'm always willing to change course if a better plan pops up. Funny you should post this. The cost of hot tanking and welding in a sump is just shy of putting in a real fuel cell. I still have some trepidation about weakening the chassis though... thoughts anyone? Quote Link to comment Share on other sites More sharing options...
CableSrv Posted May 13, 2015 Share Posted May 13, 2015 This is true, but also means you lose your spare tire well. This was something I just didn't want do lose just yet. Not only that but having to modify the filler location was a pain I also didn't want to deal with. Time will tell on whether I might switch to a fuel cell myself.

JoeK Posted May 13, 2015 Share Posted May 13, 2015 If you're worried about the rigidity of the chassis when removing the spare tire well, just weld in a cover with an access hatch where your sump is, in case you need to service it. But I really wouldn't be worried about it, there are a lot of people removing their spare tire well for fuel cells, and I've never read or heard of any issues. Losing the space is a personal question. My last sports car was a Datsun Roadster. There was no spare tire well, so if you carried the spare, it took up over half the space in the trunk. I got over that quick and just carried a AAA card instead. I'll be using the stock Camaro plastic tank, which will allow me to route the fuel filler to the original location, and not get too fancy with dual exhaust routing. But I think you'll be running a single exhaust with the CX kit, so that is less of a concern. Also, I don't know much about racing sanctioning bodies, but if you are planning on tracking the car, you may want to confirm what will be allowed. The "fuel cells" that that they sell for $100 at Summit aren't true fuel cells. They are just fuel safe formed plastic container, but don't have the bladder which is the true safety part.

CableSrv Posted May 13, 2015 Share Posted May 13, 2015 not worried about rigidity.. more or less worried about not having a spare tire? then again.. not sure I'll need one... then again.. I'm not sure. Quote Link to comment Share on other sites More sharing options...
Phantom Posted May 13, 2015 Share Posted May 13, 2015 (edited) My son got his fuel cell from www.Tanksinc.com. It is a universal pick-up truck fuel tank. Part number UT-N. When you go to the website it will show tanks. You'll want the one on the right as it's for fuel injection. You'll need ventless gas cap to go with it and to run vent for the tank. He ran his up in the rear passenger shock tower area. He has a bolt down plate covering the installation. He got the license plate bracket off a 50's/60's vintage auto from a salvage yard. Also - I've been driving over 50 yearns and I've had a total of 5 flat tires, and none of them in the last 15 years. I've had a few nails but was able to driven the tire to a shop to get it fixed. The tire well in my Z is not useable except as a small "trunk". The only flat I had in it was about 20 years ago when a really old BFG radial T/A blew out a sidewall on me.

trackzpeed Posted May 13, 2015 Author Share Posted May 13, 2015 I'm sticking with my sumped 240 tank for now... just dropped $425 in sump, an fittings, braided fuel line, pump and regulator and ...... Should look something like this when completed Quote Link to comment Share on other sites More sharing options...
EastTnZ Posted May 14, 2015 Share Posted May 14, 2015 If you're running a walbro 255 they are more pushers than pullers. I'd recommend lowering the pump if it were me from the picture shown above. Exhaust pieces and mounts look good! Good luck with the build! Quote Link to comment Share on other sites More sharing options...
Richard Oben Posted May 14, 2015 Share Posted May 14, 2015 Take this for what it is worth, PUT THE PUMP IN THE TANK, if you can. We have been at this for a while as TZ knows, every time we mount an external pump we regret it. JMHO, YMMV, Richard. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted May 14, 2015 Share Posted May 14, 2015 How you have it is fine-mine is mounted higher than yours and is fine. I wouldn't revisit this part of the build-check it off the list as done. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted May 15, 2015 Author Share Posted May 15, 2015 Thanks.... I did my research and this set up seemed pretty well vetted out. I'm on a spending spree right now collecting parts so I think my plan to complete the swap after the AutoX season may not fly. I can't wait to get this done!

trackzpeed Posted May 18, 2015 Author Share Posted May 18, 2015 Engine bay painted and prepped. Gas tank will finish up this week and installing clutch MC. Time to start thinking of pulling the LS1... And since every racer knows that stickers make give your horsepower, I estimate my garage around 1000 HP.

RebekahsZ Posted May 18, 2015 Share Posted May 18, 2015 Can you come clean and organize my garage (I will pay you)? Looks great. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted May 25, 2015 Author Share Posted May 25, 2015 Well I had a fail with sump.... I should have cut it down before welding is on. It hangs way to low.... Not happy. Wish I would have gone the fuel cell route now, dang it! Lesson learned. If I can't fix my tank I'm going you bite the bullet an order a fuel cell....

Jay Gadsby Posted May 25, 2015 Share Posted May 25, 2015 I have decided to run the oem ls1 camaro pump. Need to mod the top of the tank, but I think will be worth it in the end. No external regulator, has built in starvation solution and only requires one fuel line. a lot of the Nova and Chevelle guys use it on their non baffled tanks with no issues.

trackzpeed Posted May 26, 2015 Author Share Posted May 26, 2015 motor mounts in, Clutch MC in with SAE nut welded to Z clutch fork, AND my sump fail! with sump would have worked just fine if I would have measured twice and welded once....STUPID, and a waist of $70. Time for a fuel cell instead...any cell size recommendations? Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted May 27, 2015 Author Share Posted May 27, 2015 16 gallon fuel cell on its way... time cut out the spare tire well this weekend. No turning back now. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted May 27, 2015 Share Posted May 27, 2015 For sizing and locating the cell: determine what else you need space for: fuel pump? Dual exhaust? Battery? Trailer hitch? Parachute? Future suspension mods? If I were doing a cell with the events I participate in, I would go small and deep to limit sloshing and I would weld a good solid perimeter frame abound the bottom of the floor on the underside. I would connect it the roll cage or something else good and solid so I could use it for all of the above. Try to think easy serviceability with quick disconnects and a cleanable screen-type filter to get all the welding flash etc out. My tank had been sand blasted and it took about 5 cleanings before my screen quit having sand in it, but the FPR has always been fine. Don't forget to put a small braided grounding strap from the tank to the chassis or some track inspector may send you home. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted May 27, 2015 Share Posted May 27, 2015 (edited) When you are redesigning your rear deck, think about how to mount a spare tire, a full size floor jack and a tool box.those things add a sense of security when going to the track.
