The benefits are well worth the hastle...Of course it's less hastle to let your tank run about empty first.Getting rid of bad gas is nearly impossible..I've done it on a few other rigs and the sight of clean gas in the filter is very comforting..I have for the past couple of days been installing a factory "between the frame rail" gas tank in my '67.(alot more involved then I anticipated)..The donor truck a '68 or '69, must have sat for a long time 'cause the inside of the tank is pretty bad.(Rust And Varnish) lots of it.Outside looks great.I have power washed the inside as well as possible a couple times hopefully it's good enough. Gonna let it hang upside down in the sun for a day or so and call it good.

I can only get through about 6 gallons before she shuts down due to bad gas. I think I'll drain the gas and that will tell me all I need to know. My camper special has two tanks; the main one being in the cab behind the seats. Looks pretty straight forward to remove as it is bolted in. Does anyone know where I can find a new replacement tank?
Thanks.
Thanks.

I posted this before, but here goes. If you live near a tank builder, for oilfield supply, take your cleaned tank there and ask them to coat the inside with some of their epoxy liner spray. Take the guage sender out, and the fuel pickup. You'll have to leave it there for a while until they have a job with a bit of the stuff left in the gun, but it's well worth it.

I got a good, clean tank from the junkyard for $25.
If your tank is not the vented type, make sure your cap vent is working.
If you have the vented evap type gas tank, check to make sure that the vent tube to the charcoal canister is clear.

Those replacement caps these days are not vented and allow high pressure to build inside the tank, not good on the tank. Take a pin, heat and burn a very small hole (.006") thru the vacuum break to allow for fuel expansion when the trucks parked in the heat.

In my area you can not buy a vented cap hence hot pin poke.
I'm in the S.F. 9 bay area counties that are heavy on smog testing. Years ago I had to paint a Streetmaster and Performer Ford blue to pass the visual.
