Question about fuel lines for 1991 Chevrolet Cheyenne


#1

I am curious…a leaking fuel line would cause the truck not to start? Because some people said although a line is leaking, it would not prevent the truck from starting? I was wondering, thanks!

If it’s fuel injected (which a '91 probably is), a fuel line leak will make it impossible for proper fuel pressure to reach the injectors. Also, it might cause the truck to explode or burst into flames, so I’d fix it.
