Need help! Fuel line replacement/repair

[Dman23]

Recently obtained ownership of my Mom's 91 Camry DX (4banger) that's been sitting for the 2+ yrs or so. Car has 195.5K and plenty of life left in her. I've read and learned a lot here on TN and appreciate everyone sharing their knowledge etc.

I'm in the process of updating all of the maintenance items (tune up,valve cover, oil etc.) While trying to change the fuel filter, I crimped and broke the fuel line about a half inch down from the bolt going into the filter.

My questions is, does the fuel line run from the filter back to the gas tank or does it go to the fuel pump. I may have a chance to get one from junk yard, but do not know where to start and where to disconnect fuel line from.

A diagram of fuel line or any knowledge of where to start with in disconnecting and replacing line would be very helpful.

Thanks in advance!!

The fuel lines are single-piece back to the gas tank. You can either get a complete new one (ouch!) or replace the section you broke with a short section of fuel injection rated hose. It should work ok as long as you flare the ends to keep the hose from blowing off.

You can install a junction and a short piece of metal line. I'd recommend this over using a rubber line if at all possible.

Charlie, thank you for your assistance. I thought about adding a small section of high pressure fuel hose etc, but concerned about it leaking at some point. Flaring the end will hopefully keep it on and tight!

Thanks again!

Z,

Thanks

Just went through this madness on my '87 Camry. I ended up using a braided line from the hardware store and mounting the fuel filter with a rare earth magnet to the engine bay because the bolts holding the bracket tore off. During my search for answers I came across this link:

I hope this helps.

And if you decide to repair the lines yourself and use a flaring tool. Make sure you don't buy steel lines because you will never be able to flare it and the others lines are freaking soft so they never come out circular when cutting them with a tubing cutter. Flex fuel line was the easiest option.

David,

Thanks for the additional information and I will look into the braided line possibility. I also thought about re-flaring the top of my remaining line since I only lost about a inch or so. If so, it would work the same, but be a couple inches shorter.

Thanks for the idea and I will research the option.

After the engine rebuild, I had a leaking line at the filter input due to too many off / on tries. I installed a short patch from a new pre-made 5/16" teflon coated steel fuel line. I reusd the metric flare nut, used a brass union fitting. Cut off the bad section. Cut off the required length from the new line, allowing for the 2 flares. Swap the SAE nut for the metric nut, install the new SAE nut, double flare the cut end then carefully bend to shape using a proper tube bender. Install the new SAE nut on the in vehicle line, then flare the end. This will be tricky.
Buy, borrow or rent a decent double flaring tool, the cheap Canadian Tire one broke so I rented.
Use a cut off saw on the new line but NOT on the vehicle line, Sparks + fuel vapour = Boom!
Use a proper flare nut wrench to avoid rounding the brass flare nuts.
Do not over tighten the flare nuts, that is what caused my grief. If leaks occur carefully loosen tighten repeatedly to smooth the flare.
Fuel lines are double flared 45 degrees.

Gazelle,

Thanks for the valuable information.., I wish I'd taken extraaaa caution and not had this happen, but it's too late. I will review your method and the websites and try something this weekend.

Thanks again!
