Tips for replacing gas line

[wilkie]

I was cruising along PCH on a beautiful afternoonq when all of a sudden the Monti started bucking and backfiring, and there was a smell of gas. I managed to barely limp home, trailing a line of fuel. Under the hood the problem was obvious- the fuel hose between the fuel filter canister and the metal fuel pipe from the fuel pumps had split. Yikes!

Anyway, I'm only so-so handy at these things, so I thought I'd seek some advice before I replace the hose, which otherwise looks like a straightforward task.

First, at initial glance it looks like a challenge to access the lower clamp where the hose meets the metal pipe. Any tips on how to reach it?

Second, I'd appreciate tips as to the type and source of an upgraded replacement hose over what I would find at the local auto parts store.

Thanks in advance.

Replace all you fuel lines with the expensive high pressure fuel lines, $6-$12 per foot. I'm hearing that the alcohol in the new fuels are attacking regular fuel line, also replace the engine bay line too. That line runs very close to the header and can rupture and spray fuel right onto the head and headers. Ask me how I know, no fire and all was fine but now I keep a halon fire extinguisher in the car. As for tips on how to remove, whatever it takes. I know its a pain. Good luck

Thanks, do you have a specific brand name and source for the high pressure fuel line?

Aha. Well, pardon my lack of comprehension skills
I had to get the Montreal up on a lift to slip the hoses over those particular pipes.

Note that there are two pipes just under the right cylinder bank on the chassis member; one for fuel delivery to the pump and one for return to the tank. If I recall correctly, the return line is of a smaller diameter than delivery.

Also note that once you remove the delivery hose under there, the fuel will start flowing freely. Don't ask me how I found out. That's also the reason I have no pictures of it

Hallo Tor,

didn't hear of you since long time. Hope you are well, Monti gone?

Miss your interesting technical bulletins ! "La Tempesta"

Take care my friend

Hallo Hannelore! Yes, all is well. It's a little boring not being involved in a million things, but I'll manage. La Tempesta found a good home in May last year. Don't know what's going to happen with it since the restoration was only half done, but at least it is still in the country

Alles Gute für Sie und Dirk!

Tor, thanks for the tips. Especially the warning about the free-flowing fuel!

Had a Fuel Line let go on my car a little while ago. I have replaced it with a High Pressure Fuel Line from a local Advance Auto Store. Remember to buy the High Pressure type, its is a bit more expensive, but with the Fuel Injection in the car, it is a "must". Also get the metal clamps for Fuel Injection lines, they are also available at the same sort of store. These do not cut into the rubber as they have a "tang" under the Screw / Thread part and that allows it to slide over the surface better. Maybe a few cents more expensive, but well worthwhile. Remamber the metal lines are of different sizes, so you will need to purchase the correct I/D lines (internal diameter / size). Good luck!

Thanks, robo. I ordered the 2 sizes of high pressure silicone fuel line (expensive!), and am ready to go. However, for the life of me I can't access where the hose attaches to the steel pipes, down near the front suspension, even from below after jacking up the car (and setting it on jack stands). I might have to have the car towed somewhere that has a lift so that it can be be more easily accessed from below.

I don't know if your car is different from mine, and why, but mine is a RHD Australian delivered vehicle. I have it up on jack stands, and found it quite easy to get to the ends of the hard, metal lines under the floor. They are held to the longitudinal box sections by metal tabs, welded to the floor, from the factory. The joints for the soft (rubber) lines are about 6 to 8 inches up the firewall. In my case they are a little difficult to get to, only because my car has the steering box on the right hand side, just above the fuel line joints. On a LHD car it should be easier. Remember to use a hair dryer to heat the joint so that the rubber line becomes more pliable. Remember it has been fixed there for many years, and has probably hardened by now. Keep a tray or large container under the lines when you take them apart, to catch the fuel in the lines. Also wear some gloves so you don't get petrol on yourself. One last tip, I used some rubber grease on the metal lines to make it easier to slip the new rubber / silicone lines on and dont forget to put the clamps on before you attach the two. Saves you having to thread the clamps all the way down the lines from above, there is not a lot of room between the back of the engine and the firewall at the top. Good Luck!

Thanks again, robo. Were you you actually able to crawl under there and actually see where the hose attaches to the metal pipes with the car on jackstands ? Wow, maybe I'll have to find a way to jack the car up higher.

Wilkie,

what about these mobile ramps ? I am sure you can also get them in USA ?

Dirk finished now to install complete new fuel lines in copper. No "rain" came out... juhu I will send photos in 2 mails, just 5 each mail possible.
