The Stovebolt Site Forums The Shop Area Engine Shop Tank is full of rusty gas,looking for the best way

Need to bypass the tank with a carry can or other vessel. Thinking about putting a can in the floorboard and running a temp. line out the battery box opening to the pump.
Just travelling about 1 mile but it starves after a half mile or so.
How have you seen it done?
Or done it yourself?
Thanks

any where will work, but is there any fuel filter on it? maybe one between the tank and pump as well as one before the carb would get you where you're going

it has what looks like a fairly new one (see thru plastic) that is now red inside. I just think it can't draw enough out of the tank due to the trash.

Get a new tank.

I was supprised to find that radiator shops will clean and repair tanks. They took the 46 tank cut three 1 ft square holes in the bottom bead blasted it and coated it for about 225.00. A new tank was over 400.00. Works great and you can only tell if you remove the tank.

And I would guess your fuel pump is full of crud also.

Running an engine with old gas will ruin the carb and maybe the engine. you are right not to run it till tank is removed and cleaned. Many of us have run them from floorboard can or under hood can as you describe. Works fine, be careful. This is temp of course. OLD FILTER SOUNDS LIKE NO GOOD TO USE, gas may be a little color but NOT RED!!!!!.......... RED = GAS + RUST. "Varnish" as they call it (old, partially evaporated,chemically transformed gas), is the real killer. You may want to consider new lines and pump if it ran from that tank for any time.

Maybe not ruin but it can sure make a lot more work ...... than we really want to do.

I had the tank on my'39 boiled out at a radiator shop, here in Colorado Springs, for $40 last year. Looked like red tree sap in the bottom from the old gas that evaporated.

if it is too bad, you would probably be better off getting a new tank, I found it cheaper than having it boiled out and sealed. Around here they charge something like $250 at a radiator shop, at least all the places I called. I replaced all the fuel lines. If you find a glass top pump, there is a very fine suction screen, which will help with the stray rust bits. I got chunks from the filler neck, which just had some surface rust mostly, but at least one big enough to stop my fuel pump. You need a filter of some sort before the carburetor. It seems the new gasahol can damage some types of rubber, be mindful of that when choosing components.

I had my tank chemically dipped (Chem-Strip) for $130 and it looks brand new inside and out. You don't need to cut the tank open or coat it when done unless there are pin holes. The process also leaves the original tin coating in place as it's not acid based.

After trying to salvage my old tank, plus two carb rebuilds and having it die a couple of times on the road due to plugged filters, I gave up and bought a new tank. Your fuel pump is probably full of rust particles too unless you have a filter between tank and pump. I had to replace the fuel pump too.

Not sure what year your pickup is, but a stock tank for an AD or Task Force is pretty reasonable at $150.

I had all the rust cleaned from mine and relined for my 58 at a radaitor shop about a year and a half ago. Well I started to smell gas in the cab. Took it loose and raised one side and found a pin hole. So I am going to buy a new tank and be done with it. It cost $165.00 to have it relined. A new one cost $144.00 at Classic. You live and learn.

I had the exact same issue. My clear filter was turning pink but there wasn't any real crud in it. When I unhooked the line from my tank I barely got a trickle. Finally got it drained and found a couple pounds of red sand in it.

I ended up getting a new Spectra tank from RockAuto for about $150 shipped.
The quotes I got for cleaning and relining the old one were about the same ($125-200) but I've heard a lot of stories about the epoxy lining getting gummy after several years of use so I decided not to chance it ... and for the price, it was a no brainer.

I will second the idea for a new Spectra tank. When I bought my '53 450 based fire truck I had nothing but problems until I just replaced the tank. The new Spectra tank fit perfect.

Here are some pictures of the how the new tank fits:

Here's what I did:
Replaced the filter just before the carb.
Disconnected the hard line going in to the pump.
Bought a short piece of hard line with proper ends to screw into the pump.
Bought some clear nylon flex hose which fit the hard line well after applying a bit of heat. It was a tight fit after cooling. I zip tied it for good measure.
I taped the filler hole on a plastic gas can,made a cut,stuck the hose in and used the spout collar to cinch the tape. The hose was curly from being on a small spool, so I doubled a piece of copper elec. wire and put it in the end of the hose to keep it straight and at the bottom of the can.
Got her home, no problem, and was able to watch the fuel leave the can, go out the battery hole towards the pump.
