Fuel Systems and Drivability / Re: Preformed fuel line

Personally, I'd either go with the Moroso aluminum fuel line (25') roll, or later-model nylon fuel line, and run compression-fittings on the ends. 

If you're going for an OEM look, ignore my suggestions.

Buy some fuel hose by the foot and cut to size. You aren't going to find a stock preformed rubber line for a 47 year old truck.

Fuel Systems and Drivability / Preformed fuel line

« Last post by metalcutter1 on January 15, 2026, 12:40:02 pm »

I am trying to find a preformed fuel line for my 1979 GMC C-10 with a 454 big block.
It's the rubber line under the hood going from the steel line from the tank to the fuel pump.
I know that I can use rubber line from the a reel, but I want to keep it as stock as possible.
I don't know the part number(that would be a great help)
All of the preformed fuel lines that I have found are 3/8, this is not 3/8.
Everything about this truck is 3/4 ton, but it's a half ton.
Any help would be appreciated.

Do yourself a BIG favor!  Disassemble the ground connection you just serviced and liberally coat the terminal and sheet metal with some antioxidant paste available in the electrical department of most hardware stores.  Reassemble, ensuring the screw is tight.  This will help eliminate a recurrence.

Sonnnofa..... it was the ground.

The ground is screwed to the body (sheet metal) with a metal ring and a bolt. I undid it and noticed it was kinda rusty. I sanded the terminal and the part on the body clean, and now it works.

IDK why I don't check for that kind of stuff first. It seems it's a bad ground 90% of the time!!

Thank you all for your help!

Try using a temporary jumper wire between the socket shell and a shiny bare metal spot on the frame (not the bed, since the bed may not be properly grounded due to corrosion or a broken ground lead).

The bulb socket isn't properly grounded to frame.

1986 C10 2WD

I've had a similar issue before but this is new.

Right side tail light: Brake light works when pedal is pressed; if I turn the lights on, the light on the tail light turns on (same bulb, 2 filaments). But, if the lights are on and I press on the brake, the bulb just turns off. So no light and no brake light.

- Replaced Bulb, tried 3 different bulbs
- Replaced socket (previous one was also a newish one)

What could it be? The brake pedal switch? Ideas?
