Fuel line repair
 
88 Chevy Suburban the fuel line rotted out just forward of the braided rubber hose at the fuel pump. Can't disconnect the house at the fuel pump too rusty. Don't want to have to replace the pump There is no replacement line. At the end of the hose I have 3 of steel line. I tried to flare it and the flare cracked as I thought it would. It is throttle body fuel injection.
Will a piece of standard rubber fuel line with clamps hold up under the pressure of the electric fuel pump?

No regular fuel line will not last. You can get hose made for fuel injection at a parts store. Car quest makes repair kits for fuel lines for lines and fittings.

I did not think it would hold up. I know for sure if I even try to disconnect the hose fitting from the fuel pump tube. Tube on the fuel pump will break or leak. If I could get the fitting lose, I can make the new line my self. Trying not to replace the pump.
Thanks for your response. :thumbsup:

You can get the fittings that go into the pump from car quest. I just cut the line then you can get the fitting out of the pump to make new line.

Are you using a tube wrench to try and break the fitting loose?

A few shots of Liquid Wrench and letting it soak in may help.

I have a full set of both standard and metric line wrenches as well as double flaring kit. The Line at the pump is so rusty any movement will cause it to leak. I am looking at maybe replacing the steel line at the end of the hose and secure it with a clamp. The clamp in the photo was placed there to keep the steel tube from moving in the OEM hose. You can see how rusty the steel pump lines are. I did flare the line twice and it cracked both times right on the flare. This is an old rusted out vehicle that I drive to work once a month and leave it in the lot at work for a month. Other wise I would replace the pump. Just don't have extra money anymore.

Yea that's not good. Good luck may not have a choice but getting a pump assy.

That isn't the pump, it,s the fuel level sender that the pump inside the tank attaches to, and if it's that rusty, you may as well bite the bullet and replace it.

Wait, you cut a hole in the floor to get to the top of the tank? The tank is held in by 2 bolts after you drop the shield...

thats pretty bad. get a new one. those are not that expensive.

how much is a tow going to cost you, WHEN, that starts to leak.....

Hardway 09-28-2013 07:19 PM

Tow is free! Unless I am mistaken that was all part of the fuel pump when I priced it and looked at it at the parts store. I did manage to get it connected with a new section of line from the tank to the filter. No leaks.

"Wait, you cut a hole in the floor to get to the top of the tank? The tank is held in by 2 bolts after you drop the shield..."

Sure did fastest easy fix' In the past removing straps and dropping the tank, the tank leaked right where the straps were. Cutting a hole in floor not going to hurt anything. The rockers are pretty much gone, just keeping her running. I drive her to work once a month and park her in the lot and then drive the company vehicle. Also have to drop the skid plate, tow hitch to get to the tank. I made a cover plate and screwed it in place, put the mat back. :thumbsup:

I bought the old girl new in 1988 and she never failed to bring me home.:thumbsup:

I will look into if I can get just the sending unit as you say and how much it is.

It is all part of the fuel pump assembly and the one I was shown. $200.00
I may go ahead and replace it.

Lotek 09-29-2013 01:01 AM

That's actually 3 separate pieces from the factory, pump, sender and pickup screen, what you posted looks like it might be Airtex which is absolute junk. If moving the straps caused the tank to leak then maybe it was time to replace the tank as well...

Lotek you are missing the big picture!
It is time to replace the entire vehicle.
But that is not in the big picture.
This is my second vehicle, I drive it 10 miles round trip twice a month.
It is more about keeping it running then dumping money in it.
Replacing 4 tires may be a decison, do I want to put $600.00 worth of tires on it or is it time to go.
This is a do it your self site, sometimes ya have to improvise, adapt over come.
It is easy to say just replace everything with new.

Lotek what is the issue with cutting a hole in the floor of a rusted out 25 year old vehicle? Some vehicles come with an inspection plate.

At any rate the old girl is up and running again.:thumbup:

I have fixed many a gas line with a rubber hose. It will work fine for years, as long as you use one rated for gas. Some of the vehicles in the 60s had rubber hoses from the factory.
