rubber hose right from fuel pump? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67cst · 06-20-2004, 05:55 AM

hey guys got another question, when i swapped carbs today i ran a rubber hose right from the fuel pump, with a filter along the way, will that get too hot? im thinking now that i should have a steel line and run a small chunk of hose off that right before the carb..whats okay to do, i plan on replacing my crappy plastic filter tomorrow or monday at the latest but will the hose hold up or should i get braided hose or actual steel line?

thx, DEREK

My personnal opinion is use as little rubber line as possible.

Use as little rubber hose as you can.

You can buy a length of 3/8 steel line at the parts store and bend it up yourself. It will even be flared on the end with the fitting to screw into the fuel pump. Please, also don't use a glass fuel filter. I know everyone thinks they look cool, but having something glass with fuel in it around a hot engine is foolish. Can you say car-b-q ?

I have had trucks with them set up both ways. Metal line from pump and hose from pump. I never had a problem with either one of them.

Metal is best over all because it doesn't dry rot, split, swell, or get damaged as easy. Nowdays, the rubber stuff doesn't last as long as it did years ago. Brand new rubber stuff will dry rot and split within a few years now. Back in the day, it would last seemingly forever. I have to replace the fuel hose on my street rod every 3 years now because it dries out and splits in the bends.

As a matter of fact, the NHRA will allow no more than 12 inches of rubber hose in the car's entire fuel system. There's a reason for that. Not saying you're going to race your truck or anything, but think about why they mandate stuff like this.

I use steel braided hose for a better show look and easier installation, while it still has rubber hose in the middle the braided steel helps keep out heat.
