The Stovebolt Site Forums The Shop Area Engine Shop Replacing a Fuel Pump

Thank you to the Stovebolt community, since my last problem, a faulty starter, I now have a what seems to be a bad fuel pump. I bouhgt the fuel pump, but went to take the old off and it seemed as if the flow of fuel would never stop, so I STOPPED. Can someone help me get this pump changed.

Let me tell you the conditions, it is in my front yard on a hill. I can't get it back in the driveway (up a hill). So I have to change it where it is. I looked at the 2 nuts the are on the line. Using 2 open ended wrenches began to remove the fuel line from the tank to the pump (at the pump). The plan was to remove the 2 fuel lines then the bolts that have it attached to the block. But I don't know how to stop the flow of gas or if there is a way to stop it. I did remove the fuel cap from the tank, should I do that or does it matter.

Any guidelines would help.

Thanks in advance,
still a newbie, but trying to learn

There should be a valve under the cab floor where the fuel line comes from the tank. This is the way they came from the factory, maybe someone removed it from your truck.

That valve may be there. As I said I am new and am learning, did not even know about the valve. I will check it and if it is there, I will shut it off from there. Thanks

PS I should have said it was for a 1951 Chevy, if that matters.

can you not remove the line and then use some string or something to suspend the line in air so the fuel will not flow out, I tied mine to the hood brace,,just a thought,,Fred

It was pouring as if it was being siphoned out. I don't know if raising it would stop it, plus I was afraid of damaging the line, if I bent it, so I was being maybe too cautious. Thanks for your quick responses.

I always stick a pencil in the soft line.

I usually use a 1/4 or 3/16 piece of rubber gas line hose. put a 1/4 inch bolt in one end of the hose and clamp it. unscrew the gas line and push the hose on to the end of the gas line, take the pump off and install the new one , last part is to remove the rubber hose and install the final gas line,

Thank you all for your suggestions. I spoke to guy this evening and he also suggested the adding a rubber line to the end of the tubing and sealing it off. This is the route I will take. I can't stick a pencil in the end of it, currently it has metal tubing, not soft.

Thanks again, as usual, great recommendations, I need all of you closer to learn more from you all.

I will let you guys know how it turns out.

Ah, mine has a bit of soft line there already. I didn't know that wasn't stock.

You could also break the syphon by disconnecting the steel tube at the high point on top of the gas tank. That would still leave you with the volume in the line from the tank to the fuel pump tho. - Scott

Scott, prior to 1954 (with tanks behind the seat) the fuel line came off the bottom of the tank.

Just wanted tell everyone thank you for advising me on the replacement of the fuel pump. I have and continue to learn much from you generous people. Thanks again. Adding the tubing to the fuel line with a plug in the end, enabled me time to change the fuel pump without draining the tank.
Thanks and Merry Christmas
