Fuel Pump Install

[Jeff P.]

It's been a while ,so I learn. Any method of stopping gas flow would be of help. I thought it would eventually stop but it "keeps on comin". Thanks, Jeff

Re: Fuel Pump Install

Just did this on my '63. Needle-nose vise grips with some padding - clamped it back by the gas tank, so there was some gas from the line when I removed the line at the pump, but not much (could have clamped it at the pump, but things are pretty tight in that area). As you've discovered, if you don't clamp it someplace, you'll empty the tank when you disconnect the hose.

Yes, the bottom of the tank in every 1963-74 Corvette is higher than the fuel line so if the line is open at any point, the fuel will just gravity flow until the tank is empty. The same thing will happen if the diaphragm in the fuel pump fails.

Hose clamp around a bolt that is the same ID as the fuel line should do the trick

This is a good method I use. Also used a cork once.

Re: Fuel Pump Install

Just push an old spark plug into the hose, or a new one -- doesn't matter. Works for me.

Re: Fuel Pump Install

I use a pair of plastic slide-locking pliers with rounded jaws made specifically for stopping flow in 3/8" rubber fuel lines without damaging them - most FLAPS have them.

Re: Fuel Pump Install

I have a couple of jars of plastic and rubber plugs, these came in open ports of new and reconditioned parts. I just hunt for one that fits and plug the flow.

Re: Fuel Pump Install

My solution is to install a shut-off valve back near the tank. This makes it trivial to work on the pump or any portion of the fuel line ahead of the valve.
