I bought mine from Summit...its a 15 gallon aluminum with a GM sender
Its super easy to plumb it to your stock setup, the only problem you will have is the sending unit. I have after market gauges so my fuel level gauge is for a GM sending unit. But if you are keeping your stock gauges you'll need to find on that is close to the same ohm range...I think you can use a GM unit, but it will read backwards on your gauge (Empty=Full vise versa)
They are 2 lines involved. Feed and Return. You'll have a third line that runs to the charcoal canister,but its just for emissions venting. So you will have to cap one bung and the other is a roll over vent that you can just slap a breather filter on.
I plumbed mine with hardline, but you can use rubber and braided. You will be using AN Fittings which can be confusing, but if I were you I would try and get a fuel cell that has -6AN which is the equivalent to 3/8" which is plenty big enough. Make sure you put a return fuel filter inline somewhere as well as the stock fuel filter.
Those are pictures of mine...
Hope this helps...
