Fuel Line Leak - Toyota Nation Forum : Toyota Car and Truck Forums

Hello,

My car is a 1994 Geo Prizm.

A few days ago I realized a leak under left rear part of the car just before the rear left tire. When I look at the fuel hoses/pipesit I see gas dripping. Metal parts are rusted.

Are the parts (fuel hoses/pipes) the same with Corolla's?

How much would having all the fuel lines replaced cost?

My car is almost at 160,000 miles with no engine or transmission problems.

What would you suggest I do?

While you are checking out your gas lines don't forget to look at the line right where it goes into the tank. I had to drop gas tanks on 2 different Toyotas to replace the line going into the gas tank.

If we assume all fuel lines are bad, how much would -say- Toyota dealer charge for labor and parts?

4 or 5 years ago the fuel tank assembly was between 100 and $150. You had to drop the gas tank to change it. It is a PIA job on a rusted car. If you can't or don't want to do the work yourself you will probably pay more than the car is worth at the dealer.

I think the tank is in good condition. The lines going to the tank are bad.

You want to check the line going into the gas tank. This is the expensive part I mentioned. This is the part that has the fuel pump that goes in the tank. If all of your lines look bad this part is probably bad. If it isn't bad get some undercoating spray to help slow the rust. I sprayed my 89 Land Cruiser yearly after replacing this part on my 88 LC. We junked a good running 89 Corolla all-trac wagon because of the fuel line failure and years of neglect by the owner. But that is a story for another day

This is my candian deal experience. If you wanna change the fuel lines at the dealer will only do the job if they do all the fuel and brake lines running from front to back (not only one or two for instance) and they charge ~1,600 cad. Crappy tire will do ~1,000. mechanic friend ~500. Yourself the parts are cheap to do the lines maybe ~50 but it can be tricky(done it on both my corolla's thought so it is managable and also common)

The filler neck to the tank is an expensive part from the dealer. But you can find those from a used tank place. And it'll be OEM part for ~80cad. So that's not to bad.

Thanks my two cents

For a temporary fix for the filler neck, I got a piece of clear tubing about 2 ft long that would fit on the end of the gas nozzle. insert hose into filler neck while pumping gas with your other hand. Don't over fill. You may find you don't lose any gas this way. I did this with an 85 Camry.

I'm confused. You took a piece of pipe put in to the tank understand that. But the other end what did you do with it? Sound like you took the pump handle and put it to the clear hose to pump gas while you were holding it together??? LOL am i a noob and don't understand what he's saying or what?

I am sorry I didn't describe clearly. My fix only works if gas is leaking out of the upper part of the gas filler tube. If the leak is low near the tank it will not work. I used the clear flexible hose to get past the rusted out hole in my filler pipe. When I was finished pumping gas I would slowly pull the hose out being careful not to spill gas. This is a temporary fix if you are leaking gas from a rusted out filler tube. Any hose that fits tightly on the gas station fuel nozzle and fits into the gas fill opening on your car will work. When I made mine I found a hose that fit into opening and pushed it in as far as it would go. I cut hose about 6 inches longer so I could attach gas stations fuel nozzle to put gas in car.

Bottom line- If you have to pay someone at a retail store to do it you will spend some big bucks. You can do it yourself at a fair price but it IS LABOR INTENSIVE and you need to work safely around spilled fuel because YOU WILL SPILL SOME!

You can replace the lines front to back with steel or copper tubing.

I have used a "double clamp" on pressure hoses when the OEM or someone who crimps hoses was not available.

The filler necks rust out and yours may come apart when you drop the tank. Be prepared for it.

You should have enough info now to get the job done one way or another.

I do not have the experience to do it, since it is fuel system I am not comfortable with it either.

Does the tank have to be dropped to replace the fuel lines, replace rusted portions?

What are the part numbers for fuel lines? I can not see it anywhere online. I hope they did not stop making them. The parts stores online do not show fuel lines listed in their catalogs.

The worst looking part seems to be the fuel return line if I am not mistaken.

you shouldn't need to drop the tank, take the fuel pump access panel out and you should be able to sneak the lines in atop the tank with some wiggling.

speedy25 · 05-05-2011, 08:58 AM

Fuel lines are NOT typically available form aftermarket sources. In the past I bought brake line and bent it to fit.
