Re: 1962 GMC 305V6 4WD Slow DD Build - Cecilia (Pic Heavy)
 

Mine turned out to be a "pizza-junk". I finally got time to jump out there and fiddle with it today for a while. And get this, the Powder Puff made it out too! Once they get older they just don't like to sweat a drop anymore. I've come to accept it I guess, but when they get a little dad-sick and come out from the air conditioning to spend time with me it sure does make me happy.

So we started off pulling the 5 screws, two nuts, and one pipe off the sending unit - again.

Then on a whim, I thought, "May as well remove that nasty old gas in the tank while I"m in there" so I removed the bolts holding the straps on the tank. That's really all that's holding the tank in there. Plus one worm strap thingy on the fuel neck.

The worm strap was 3/8", I could barely get to it with a wrench, but here's what it looks like.

These straps are just springy metal straps, but they're bent to fit the tank. If you don't move them behind the tank, you'll swear it's bolted down somewhere else.

I picked it up from the passenger side. That made the driver's side where the fill tube is go down, With a little wiggling it popped free and didn't spill a drop of old, yucky gas.

Oddly, the whole collar came loose instead of just the part I loosened. I guess it was loose way up in there where it connects to the fill hole.

And although my sending unit said I was empty, it was half full of yellow, gross gasoline. No wonder it was so heavy!

And when I emptied it out in responsible manner that the EPA would approve of, and not in dead spot in my yard, :teehee: , all the insides were covered in what looked like rust!

And check out what my sending unit looks like after only a few weeks sitting in the tank. The float even has holes in it!

So now I'm thinking I need to replace the gas tank, or maybe coat it? And I definitely need a new sending unit.

Re: 1962 GMC 305V6 4WD Slow DD Build - Cecilia (Pic Heavy)
 

I recently went through the same scenario with my '67. My recommendation would be to go with a new tank. They're not that expensive.

Re: 1962 GMC 305V6 4WD Slow DD Build - Cecilia (Pic Heavy)
 

Wish you were closer Fetch, I've got a nice clean tank from a '64 Chevy truck you could have. Probably would be the same.

Glad to see PowderPuff joined you. :welldone:
Maybe that's what's up with my tank. It always hits empty at about half a tank, even after I replaced the sending unit. I thought the gauge might have an issue.

Re: 1962 GMC 305V6 4WD Slow DD Build - Cecilia (Pic Heavy)
 

I looked at some of the guys that did the coating/cleanouts. Not real convinced that isn't just causing more trouble with scale breaking off, more rust later, etc. I think you're right Ed. :thumbsup:

Thanks Dac! This isn't the first time I wished we were closer! I'm going to start pouring green persimmon water between your place and mine tomorrow morning. By this time next year we should have all the space drawn up between us then we can do some real building, haha! (Green persimmons = super sour. Pour on ground to create instant black holes. Dilute for safety!)


I also think the sending units they send us don't reach to the bottom of the tanks. I'm going to monkey around with this when the new parts come in and see if I need to bend the intake hose down further, or maybe add a pickup hose. :newidea:


Well I broke down tonight and place an order with LMC Trucks. I usually order from Brothers, but dang they wanted over $60.00 more for the exact same products! Not today, Satan!

Here's the bill for a sending unit and new tank:

1 32-5921 GAS TANK-17 GALLON 149.95
1 32-4015 SENDING UNIT 49.95

Parts Total: $199.90
Delivery & Handling: $27.75
Oversized Part Fee: $20.00 (Fuel tank)
ORDER TOTAL: $247.65

Re: 1962 GMC 305V6 4WD Slow DD Build - Cecilia (Pic Heavy)
 

When I bought my replacement tank I also ordered a new sending unit. I ended up using the old sending unit as the fittings were a different size for the fuel line to the carburetor. ( I think they were the next size smaller)

If your filter neck grommet is in bad shape, now is the time to replace. I will say one thing, the new rubber items didn't hold up nearly as well as OEM items, mine is cracked after a couple of years.

Re: 1962 GMC 305V6 4WD Slow DD Build - Cecilia (Pic Heavy)
 

Good idea! Mine is cracked too. I ordered another from Steele Rubber because everyone says they're tough stuff. Expensive stuff is more like it!
I sure hope it lasts!

Fuel neck grommet p/n: 70-1942-41

1 $39.70
Subtotal: $39.70
Shipping: $11.73
Tax: --
Total: $51.43

Re: 1962 GMC 305V6 4WD Slow DD Build - Cecilia (Pic Heavy)
 

I checked out their site. Interesting that less parts were listed for the GMC than for the Chevy even though most of the items they list can be used on the GMC as well.

The next time I work on my tank I going to install a HydraMat Fuel Pickup.

I will have to adapt it from 3/8" NPT to a 5/16" line. It will get every drop of fuel out of the tank.
