are these still being sold? and how about straps
gtxbullet APR 17, 09:28 PM
pictures of the actual product with detailed measurments and specifications would help greatly!

I'm interested in one that would use the stock sending unit and is set up the same for fill/vent.

OK, so I forgot that i needed a new tank, and now im interested. I've read the thread twice and I still have some questions, so please bear with me.

1. I understand the straps not being used, and using the X brace to hold it in, just how "tight" does the tank fit up into the tunnel, can you still get to the original strap location or do you recommend cutting them out?

2. I have swapped out the stock motor for an LS3, no mods were done to the stock tank, except that a new fuel pump installed, so will my stock "stuff" just swap in, will anything need to be made longer/shorter?

3. after I remove my stock tank, will the two rubber hoses, (gas/vent) fit back on the new tank, or have the locations been moved? If I request "a stock tank" will everything just fit like a "stock" tank?

4. With the increase in volume, does the gas guage still read 1/4 tank at 1/4 tank, 1/2 tank at 1/2... you get the idea, does the guage read what is in the tank or will it be off?

5. what is shipping to zip code 23456

6. Do you take paypal

Thanks

Ill try to do this in order.

Yes these are still available for purchase. They are custom built upon order so I just have to get with Tony, my builder and double check that everything is still good on his end.

The tank has gone through several design changes. Since my original tank was made we have lengthened it, cut the height a bit and added a slope to the front. My tank is still in my car that I drive 2 or 3 times a week for the last year or so. The straps should be figured out by the buyer as I dont have a way of designing a strap setup to sell right now. My best suggestions would be to either lengthen the existing straps (add a piece in the middle, welded bolted or riveted on), using the existing cross brace as my tank is held up with, or creating a new way to strap the tank. People have suggested two straps similar to the cross brace that could bolt to the floor pans somehow. Seems like a decent idea just dont have the ability to test it out right now. My tank held in with the cross brace fits very tight, I had to use a jack to hold it up while I started the bolts. Shouldnt be that tight with the reduced height but I believe it will still be a tight fit as in not bouncing around in there.

The tank I have uses the Fiero sending unit and pump assembly. I am not happy with the way it seals though, but you could design some other type of seal, put a liquid (fuel safe) sealer around it, etc. I used the stock O-ring and it will leak if I fill the tank all the way (out the top). It is possible the ring could have moved though causing it not to seal. If you choose to use the stock stuff Im sure it could be made to work just fine with some more thought put into it.

Part of the increased capacity comes from moving the vent and fill tubes a little higher on the tank allowing more gas to fill the void. Mine is all the way at the top of the tank and I was able to still use the stock hoses all the way around, no troubles putting them back on.

The gas gauge in my car doesnt work right. Period. I bought a brand new Fiero Store sending unit with the updated sender design to put into my new tank. I dont know if my gauge itself is screwed up or if its the sending unit but it reads all wacky. Close, but wacky. It will go all the way to E when its empty though, half tank seems to be all over the place and full seems pretty close. Again not sure if its the unit, the gauge or what. I know that with the redesigned height it is pretty close to stock tank height inside where the sending unit is, and the placement on the tank is stock. With the marine sending unit we are working on, we may be able to get a much more reliable and accurate sending unit for less than a new FS one. The only drawback would be having to use an external fuel pump (though some may see that as a positive). In short, it should work as it does now, just be more careful sealing the assembly to the tank when installing it than I was and you should be pretty much stock for stock swap.

Shipping on the last few tanks was in the $35 or so range, you are fairly close to FL so it shouldnt be more than that. If interested I will get Tony to build the tank with a $300 deposit and then bill you for actual shipping cost when its built and ready to send off.

I do take paypal but it really bites into the cost. I would need to charge the 3% fee to be fair unless you decide to trust me enough to send the money as a gift to avoid fees.

I will give Tony a ring tomorrow. If anyone is serious about getting a tank made PM me and we will work out the details. We can change or move things if you decide to, I just need to know exactly what you want before I can get it made.

Oh and there are pictures on my build thread of the tank. I dont have exact measurements because I havent touched a finished tank in a while.

I realize this is in the mall and not tech, but this is such a huge safety issue it really needs to be stated. The reason for the "void" above the filler necks is there is for expansion. If the tank is full and the fuel expands from heat the void area absorbs the greater capacity of fuel. The later cars had the expansion tank located in the right quarter panel, allowing more fuel to be in the tank. The posability here is that without the airspace to expand into you likely can push fuel out onto the ground (or garage floor). It can and does cause fires. I heard that Fieros are prone to it, no need to add likelyhood to the history.

I appreciate the info, and would like to point out that I did mention in this thread that moving the vent tube up doesn't leave airspace for expansion an also that I ask every customer that buys one exactly where they want their vent and fill tubes located. I don't just put them wherever, you have a choice.

I will also point out that I have an 85 with no expansion tank and my vent tube is all the way at the top and has been in my car for over a year and it has never overflowed from expansion.

But yours leaks, as you mention above....so....that's not really useful to mention your year of experience, is it?

It only leaked on me once, when I kept pumping gas into the tank after it clicked. It came out the seal where the sending unit attaches but as soon as I drove it a little over 2 miles I parked it for a half hour or so (hot) and it never came out of the tank from expansion after that. LIke I said I suspect the seal may have shifted when I installed the sender which is another reason I want to figure out the marine sender deal. I am just waiting on them to send Tony a price on the senders with 0-90 ohms and the right size for these tanks.

Those marine senders are made to mate up to a flat aluminum tank anyway so Im sure the seal will be much better than I could get using the big O-ring seal under our sending units with an attaching ring screwed to the tank as mine is. It works fine but I would feel much better knowing my sender was sealed flat across the surface and made for that application.
