Guest Fast Frog Posted June 8, 2000 Share Posted June 8, 2000 Anybody had experience switching a Z gas tank?? I'm planning another ZV8 project and would like to remove the old stock gas tank and fit a new one that will allow a 2 1/2" exhaust to come out the back on both sides. As you know, with the stock gas tank the exhaust can only come out the back on the drivers side. If possible, I'd like to do this without a lot of hassel and expense!!

Guest Anonymous Posted June 8, 2000 Share Posted June 8, 2000 Hey Frog look in the back posts, I had that same question a while back and I believe it was myron that helped me with that topic, but it isnt a big deal. just install a 15 or 16 gal fuel cell and there is plenty of room on both sides for exhaust. but just the same if you search the archives I think you will find all the info you need . good luck frogman,,, Tony ------------------ 74 260, sbc 350, 700r4, and a few little HP Mods.just gettin started good. speedtechcoatings.com Quote Link to comment Share on other sites More sharing options...

Mikelly Posted June 9, 2000 Share Posted June 9, 2000 Check out my tech article about the Fuel Cell Swap I did... That should give you everything you need to know.

pparaska Posted June 9, 2000 Share Posted June 9, 2000 Nothing against fuel cells or anything, but in talking to Henry Costanzo, he put an RX-7 (second generation?) tank in his V8 Z show car to get mufflers on both sides. He's president of the Georgia Z club, http://www.georgiazclub.com/ , and his email is: hcostanzo@gowebway.com I tackled it a different way, with too very large Dynomax Hemi Super Turbo mufflers on the left side of the tank. Of course, there was some surgery required to the spare tire well. I think I may be able to fit a donut spare in there, at least partially into the well. You can see the exhaust installation at: http://www.tidalwave.net/~pparaska/exhaust.htm Not saying it's the best way to handle two mufflers back there, just the way I chose to go.

Mike kZ Posted June 9, 2000 Share Posted June 9, 2000 I welded a sump to the bottom of my tank, removed the spare tire tub, and moved the tank to the center. I just have to make some new strap mounts, and extend the fuel hose to the tank. Quote Link to comment Share on other sites More sharing options...
Danno74Z Posted June 9, 2000 Share Posted June 9, 2000 Fast Frog, I too plan on putting in a 2.5" exhaust system and since, for now, I'm concentrating my efforts at the rear of the car I'm looking at alternative fuel tanks. This is what I'm "planning" on doing. I don't know if this will work but I'm going to give it a try. Many folks, either alter or remove the spare tire well to ease the fit of a duel exhaust system into the Z. Later this summer, I'm going to remove the donut and put in a tank from a 1986 turbo Z. I got the tank from a salvage yard in NM.. The tank is complete ( I asked for everything.) What is nice, is that the filler and downspout are on the passenger side just like our 240,260,280 cars. But what is real nice is that when I crawled under a mid 80's Z (parking lot at work - got permission - guy thought my request a bit odd) the tank is situated in the middle of the car with a long downspout to the center section of the side of the tank. "Our" old tank has the following approximate dimensions; depth - 6"-13" depending on the side, width - 18" and length is 35". The new tank dimensions are; depth 11", width - 21" and the length is 30". For the most part, the new tank is symmetrical with no real odd ball pattern to it. Like I said, I got the tank, all the gaskets, downspout, filler opening, straps sending unit and the pump. I'm going to try and use the in tank pump for the fuel injection system on the LT1, but this pump may not have enough pressure or capacity for the new V8. I will most likely use an after market external pump made for the LT1. We'll see. Locating the new tank in the center rear area should allow enough room for duel mufflers and allow proper venting and filling of the tank. Also, this tank is setup for fuel injection, so I don't have to invent anything to make it work for my application. An added benefit is that the new tank is 19 gals. vs 16 gals. Naturally, I know I will run into snags but probably no more than fitting in a fuel cell and its issues. If any other member has done a swap like this please let me know. But I may be braking new ground here. This should work. Danno74Z Quote Link to comment Share on other sites More sharing options...
Mikelly Posted June 10, 2000 Share Posted June 10, 2000 Good idea DANNO.... I looked at this and just couldn't find a decent unit to transplant into the car from a salvage yard.. The ZX tank is MUCH nicer than the Z unit. They also coated them better.

Guest Fast Frog Posted June 12, 2000 Share Posted June 12, 2000 THANKS guys!! Particularily Danno74Z: Keep me posted, Danno74Z, on your ZX gas tank effort. This sounds like the way I may want to go if I decide to continue along this line. Thanks, again!!! Quote Link to comment Share on other sites More sharing options...
