JustinOlson Posted April 16, 2008 Share Posted April 16, 2008 Well, I've always wanted to install the fuel filler behind the license plate in my Z. Ive been working on a design for the fuel cell I'll weld up to make it work. Let me know what you think. Regards, Justin Quote Link to comment Share on other sites More sharing options...
hughdogz Posted April 16, 2008 Share Posted April 16, 2008 I think you may need to design in a more vertical section of the elbow. Just thinking of filling up and fluid possibly spurting out. Or, if you're parked on a hill with a full tank (or accelerating hard), would the cap seal it enough to prevent leaking? I would also measure the CLR of an actual pump nozzle and throw it into SW (or which ever modeler you're using) to make sure it will slide in / out just right. Otherwise, looks good Justin.

JustinOlson Posted April 16, 2008 Author Share Posted April 16, 2008 Thanks for the suggestions Hugh. I need to think more about fuel sloshing back against the filler cap.... Maybe I could do a trap door to keep fuel out of the filler neck. I'll go to the chevron with my calipers tonight. That ought to be funny Justin Quote Link to comment Share on other sites More sharing options...
Guest 280ZForce Posted April 16, 2008 Share Posted April 16, 2008 Ok, ok... I suppose I'm leaking my progress pics out lil by lil already, so why not... here we go... I have some 1.5" aluminum pipe that I will cut an angle, then cut a hole in the driver side top portion of the fuel cell on the back side of it by the tail panel. Then weld in the alum pipe to the cell and run some fuel filler hose off the filler at a slight 90* downward bend into the new alum pick up. this is still a bit rough...

johnc Posted April 16, 2008 Share Posted April 16, 2008 Never liked the idea of the fuel filler/cap sitting at the back of the car. A good rear impact can damage the filler tube and cap and cause a fuel leak. Nothing like stepping out of your car after getting hit a a light and realizing you're standing in a puddle of fuel. Even the NASCAR hillbillies recognized this decades ago and put the fuel filler on the side of the car. Quote Link to comment Share on other sites More sharing options...
Guest 280ZForce Posted April 16, 2008 Share Posted April 16, 2008 the same thing could happen with a side filler on a side/t-bone impact. With a fuel cell that has a sump you're looking at that problem happening anyway cuz of the sump fuel lines being at the rear of the car. I wanted a fuel filler that I could easily hide inside the car by boxing it up and also still give me the most cargo space to do other things that I might need space for and that option was the most out of the way.

Chaparral2f Posted April 16, 2008 Share Posted April 16, 2008 I moved the filler to the rear on my Z31. I would change the angle of the neck on the fuel cell so that it is more vertical. I used the stock fuel tank and and filler neck from the car and angled it up about 45 degrees and haven't had any problems with fuel coming out the filler, and My car had a major squat under acceleration. On a lighter side, I never have to remember which side the filler is on. Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted April 16, 2008 Author Share Posted April 16, 2008 280zForce, What kinda filler cap is that? Justin Quote Link to comment Share on other sites More sharing options...
Guest 280ZForce Posted April 17, 2008 Share Posted April 17, 2008 280zForce, What kinda filler cap is that? Justin Pop-up cap ftw! You push in and twist, it pops up and then you unscrew it. It comes w/ a steel weld in bung as well, got it off a guy on ebay, I guess they are used on motorcycles mostly. But here's the link to 1 from him. http://cgi.ebay.com/ebaymotors/Custom-2-Raw-Alum-Pop-up-Gas-Cap-with-Steel-bung_W0QQcmdZViewItemQQcategoryZ35557QQihZ022QQitemZ350047894783QQrdZ1QQsspagenameZWDVW Hope that works for ya - J Quote Link to comment Share on other sites More sharing options...
Six_Shooter Posted April 17, 2008 Share Posted April 17, 2008 I'm planning a similar deal. I have looked at using a late '60s Camaro fuel tank to do this. Unfortunatly I don't have the dimentions to verify if it will fit or not. I'll likely build a fuel tank from scratch, due to other plans I have for the rear of the car.

JustinOlson Posted April 17, 2008 Author Share Posted April 17, 2008 Funny the reason I like this is because my dad has a 68 firebird that we always drive around in. Justin Quote Link to comment Share on other sites More sharing options...

JSM Posted April 17, 2008 Share Posted April 17, 2008 Your car is looking very nice. I like the rear mount gas filler. Pop-up cap ftw! You push in and twist, it pops up and then you unscrew it.

Boy from Oz Posted April 17, 2008 Share Posted April 17, 2008 I'm working towards the same concept. My approach is to utilise as much as I can from the LS1 donor car. To that end I have kept all the fuel tank items in the hope I can marry them to an aluminium tank I am constructing. One item is the one-way valve seen in the photo. You may want to consider picking up something like this new or from a wrecker. Quote Link to comment Share on other sites More sharing options...
