    Any one know of a better after market gas tank for a straight top tube frame? im looking for something longer, thinner and sleeker than the stock stamped steel tanks that come with the kits.

    I bought this tank. It was not cheap, but it looks great. 13.5 inchs long 1.2 gallons.

    wow gasbikeproject, that is so nice looking. You just gave me the best idea for my next build. Hope you dont mind but i saved this picture and plan on making this someday.This is the first build Ive seen using those kind of rims and a jack shaft.

    very impressed with your bike, good job

    this one isn't "sleeker", but it is bigger and looks better than the stock tanks. This is the one I bought. Shipping was only like 3 days from Taiwan

    Whizzer Fat Tank

    the channel is deep enough that it covers the whole cross bar and then some-- keeping it from looking like it's just perched on the bar like the stock tanks. Mounted with U bolts from the hardware store

    it costs $50 less because it's less than half the size :)

    No, my 4-liter tank holds 136 fluid ounces; yours contains 154 ounces. So 18 ounces more capacity for $50 more.

    BTW, I also carry an 18-ounce aluminum fuel container in my bottle cage. It cost me $5.95.

    Sooo, I carry 154 ounces for $44.05 less than that 1.2 gallon Whizzer-type fuel tank.

    I only ride about 50 miles weekly, at most. So I fill my gallon jug as often as I fill my Toyota Camry. Instead of carrying all that gas in my tank(which weighs 9 lbs), I ride with a half-tank of gas. :cool2:

    Im not really concerned with capacity, truthfully a 1/2 gallon would be plenty.
    i once saw a long thin smooth tank for one of the chopper styled bikes, or maybe one of the old school long thin coffin styled tanks you see on retro type bikes.
    anythings better than that stamped steel "lip" on the pressed tanks... i might have to make it myself.
    thanks for your comments.

    nope, the one pictured is 1.8 gallons, or 230 ounces. Standard Whizzer thank is 1.2 gal, but that's not a standard tank. :D

    I wouldn't know that because I didn't buy the 1.2...

    but I don't think that either tank is what the OP is looking for anyway. The one Motopsycho is probably more what the OP wants.

    When I was first looking at the 1.8. I was afraid it would be too wide to comfortably pedal, but it's fine.

    that tank is a West Coast Choppers bicycle tank (you have to weld all the seams and install a cap/bung and a petcock)

    yes, that is exactly what it is. I actually used silver solder to seal all the holes and seams. I did not weld in a bung for a gas cap, I am using an oil fill cap from a valve cover and it has a rubber plug on the back. I cut the hole for the gas cap and the rubber just pushes into the hole sealing it tight.

    I added 2 fuel line outlet tubes made out of copper tubing, silver soldered into holes in the sides of the tank at the rear. I am using an in-line shut off valve because it was much easier than trying to put a screw in petcock into the tank. Besides that, i was able to hide the in-line shut off valve for a cleaner look.
    You also have to pressure test the tank to check for leaks once the welding/soldering is done. yes, it is safe to use silver solder to seal a gas tank, but it has to be silver solder and you must use acid flux and a propane torch to do it right.

    you have to make a mount that isn't ugly, so i made a hidden mount under the tank. This mount allows the tank to be mounted to the frame very securly, and it also allows me to remove the tank in about 20 seconds if i need to.
    I also ground down the welds on the front of the tank, filled the area with bondo, slightly re-contoured and smoothed the front of the tank. Paint is metallic black laquer with clear laquer over it.
    There is a lot of work in making one of these tanks actually capable of holding gas, so if you can't weld, braze, solder with a torch, do body work and paint, i would not attempt it.
    the tanks are made out of some heavy gauge steel, they are not tin, and they are not flimsy at all. they are much thicker and stronger than the kit supplied gas tanks. I picked mine up for $7.00 off e-bay.

    here's another west coast chopper tank that i did. this one is on a non motorized bike, so i didn't bother welding it all closed. I just ground down the welds on the front, filled the area with bondo and smoothed the front of the tank. I did cut a hole and put in a more realistic looking gas cap, and it's the same style as the one i used on the above tank. paint on this one is metallic orange laquer, with clear laquer over it.
