I have a 1977 Chevy K10 Trailering Special, this is my first truck and has been a learning curve due to having no experience with vehicles. The truck was parked for 6 years behind a barn because of a bad fuel system. Last year I pulled it out and was going to fix the truck but did not have funds to properly replace the fuel system. This spring I finally decided to go all-in and fix the truck with the help of my brother.

I completely replaced the fuel system (except for the fuel selector valve) which made her come back to life. I put two new saddle tanks and made new tank straps and the felt padding due to the straps I bought was too big for the tanks. The sending units are new but they still give inaccurate measurements with a good ground because I wire wheeled the metal before I put it on. I replaced all the rubber fuel lines except the metal ones because they were still in good shape. The fuel pump was replaced and was relatively easy to install with a tip from my brother. My brother also rebuilt the carburetor which is an Edelbrock 400 and made a huge difference in performance.

I recently changed the distributor cap and rotor, vacuum advance, and vacuum lines due to it having a vacuum leak. I discovered the cap on the distributor tree had come off because the hissing noise the truck was making and the frequent surges. The truck is a lot quieter and runs more efficient.

I running 31in Yokohama gladiator A/T for tires.

The current dilemma is the fuel selector valve went out on my dad while on the highway and I have to say this was the first time I let use the truck since I got it running. Right now I rigged it up to where only the left tank is being used. I’m in a predicament right now because the old selector valve is discontinued which is the GM 467513. The replacement part is the U7001 which is a 6 prong plug while the old one is a single circle plug. The next step will be to wire up the new adapter which is out of my capabilities. This is a job for my brother and I know you are going to read this post.

I’m debating on a name for the truck but it must deal with rust because she has a lot of it.
 
No, it is a 6 port valve I have looked everywhere and cannot find it.
 
ah o.k. there old school for sure .

my 2 tank setup i just pump fuel from pass tank to driver tank . i have a key hot only switch with a red light for when its pumping over so i dont over fill or forget .

good luck finding one that will work .
 
Yea, that will work. The issue is the wiring. The older valves had just one wire going to them, however, the newer style has that multipin plug and best I can tell, it is not as simple as just finding the one port that needs to be hooked up. I could be wrong, but I'll be looking into it a little more seriously soon.

I'm his brother, btw.

Jack, snap a pic of the SPID when you can. I'm impressed with the number of options on this truck.

Also, if someone can clarify the Trailering Special, that would be great. Just curious as to what the actual differences are between this truck and a standard half ton.
 
Pollak 42-103
Standard FV-1
Napa 2-2057
The standard part number does not have a return line (3 port vs 6 port) and the line size is 5/16 instead of 3/8.

I have a used one wire, 6 port valve that worked when pulled that is correct. PM me your address and I'll drop it in the mail to you.
 
Mine was acting up a month ago, I beat on it and it decided to work fine ever since.

Pretty sure I’ll just change it to the new style solenoid when it gives me trouble again.

The only thing I don’t like about the ones listed above is line size. But I guess it prob wouldn’t be an issue for my stock 454.

Is that the one I sent you?
 
Yes, I didn't need the return line so I passed it on to someone else that could use it. I still need to install a new valve on my C10 and have a couple other valves to play with.
:saweet:


Hell yeah
 
Nice truck. My dad and I each had K10's exactly like yours. Both were 1980 and one a Silverado the other a Scottsdale. I learned a lot from dad's truck as I was driving it as a sophomore. I was 16 then and had 1 year under my belt learning and studying all about GM's and Ford's.
