Re: 62 GMC build
 

Thank you for the pictures and blow by blow on the fuel system. Who was the supplier for the new tank? That will be my next project in the "start up", and I'll have something to refer to. I'm working on a 23 year barn storage situation so it'll be real interesting to see what kind of gobly gook is in that tank!

Re: 62 GMC build
 

Tuckers in Las Vegas. They are a mail order company and so far they have what I need in stock.

A couple things I can think of...

Make note of the length of the filler neck before you disassemble it. The replacement hose I bought was quite a bit longer than the one it replaced. I pushed it farther down the neck of the fuel tank and pushed the other part farther into it to achieve the same length as original.

Assemble everything mentioned above before you install the tank in the vehicle. Then raise up the opposite end of the tank to get the fill assembly through the hole in the body. The hose clamps are difficult to reach when it is in position . That is why you want it close to the original length and already tightened.

I WD-40ed the grommet in the body to allow the fill tube to slide through easier.

This is what worked for me but it is the first one I have done so there might be better ways.

I decided it was time to soften the ride a little.
As I mentioned before its days of hard work are over and I wouldn't mind it sitting a little lower. It has a lotta rake and it is still pretty firm with too much rebound.

I already removed the quarter eliiptic helpers which has no effect on ride height but did effect ride.

Next to go are these coil over/helper spring/shock absorbers...

I have a pair of stock Jeep(TJ) rear springs but I already know they are too soft.
I also have a pair of newer Jeep(JK) springs for a 4door Rubicon. They are longer and a thicker coil. Neither of them look like much compared to the stock spring.

I had a couple sets of shocks with potential but the KYB gas adjusts are pretty close to the right length.

So I slapped it all together... The 50 year old bolts didn't give too big of a fight and I'm not bleeding:goodjob:

Now that's a Great shot! Nice work TD.

Re: 62 GMC build
 

Look for a set of 1/2 ton coils. The 67-72 chevys are pretty easy to find.

Re: 62 GMC build
 

Thanks! ...cell phone camera. I was trying to get a sunrise shot but the rain chased it away. Maybe rainbows are to make up for it?

I will look for some. I was mostly experimenting with what I had on hand. I have a 63 1/2 ton but I'm selling it back to my friend I got it from. Maybe I can get them from him...

I took the intake and valve covers off to see if the all-thread that was in the motor did any obvious damage

No sludge!
The intake gaskets were wet with fuel and the bolts weren't very tight. The vacuum line going to the tranny was loose also.
I decided to change the plugs while I was rooting around in that greasy mess. I was about half way done when I noticed this

I pulled a plug out of each spare motor and they were long like the new ones so I proceeded. I also checked part numbers on Rock Auto and didn't see a year difference.
When I was done it ran and shifted much better!

I also wanted to lower the front a little so I turned the torsions down some...then I went some more just to see how it would look. I decided to put the TJ rear coils in...

I like it! The nice thing is I can put the stock springs and shocks in the rear and crank up the torsions in about 20 minutes and it would be back to a functioning ¾ ton truck.

Re: 62 GMC build
 

Original plugs were 3/8 inch so they didn't smack the pistons. Lots 305s had probs after someone stuck long plugs in them and they hit the pistons.:ahhhh:

Re: 62 GMC build
 

This is the first I have heard of that! I think I will go pull one and see if it is smashed shut? It is still running great...
