Fuel line

Hey guys, in an attempt to change the fuel filter in the carb of my 1978 c10 silverado 350. The steel fuel line from the carb to fuel pump will not come off. Tried everything it is loose at the nut but the line that connects to the nut to the carb will not come loose. Just keeps bending and twisting, eventually it will snap. My question is besides bending my own new stainless fuel line would a rubber or
Stainless braid line be acceptable for the temperatures in the engine?

Re: Fuel line

the line will prob come loose if you take the carb off. It is probably slightly bent and putting tension on the carb and then not wanting to come out. as far as fuel lines go, you prob would need to get a fat insurance policy on the truck before you hook up that rubber deal you are talking about.... I would recommend going back with steel. Is a steel line hard to find?

Re: Fuel line

I had a similar issue where the fitting would break free from the carb, but the line would not break free from the fitting and kept trying to twist with the nut-fitting. I ended up cutting the line and then splicing the lines back together with a short piece of fuel injection rated fuel line. It's much tougher than the regular stuff. Underhood temps aren't really an issue unless you lay the line directly on the engine or a header or something like that.

Re: Fuel line

Cut out the twisted section and splice in a section of 3/8 fuel hose with decent clamps and forget about it. You're talking about a couple of inches of hose. It's fuel hose. It's rated for way more pressure than your pump supplies and its rated for underhood temperatures. Those engineers at Gates or Dayco designed it for this purpose.

I just bought a new roll of Gates 3/8 low pressure fuel system hose the other day. It's rated for 50psi pressure at 280 degrees Fahrenheit continuous. You can buy it at any parts store for like a buck a foot.
