Installing upgraded fuel lines

[DMC3165]

Hi all,

I was just wondering if there was any surprises or anything special I needed to know when installing new fuel.lines. I was going to approach this the same way I do plug wires and just do one at a time. But I've never done them before so I figured I'd ask first. Also Is there any special way to prime the system after its been emptied of fuel? Or do I just crank the ignition until it starts to go. Any suggestions would be helpful.

Thanks,

All depends on what lines you are installing. Styles are different depending on source.

Whichever one Rob has. Going to pick them up late today or tomorrow.

Then you should be asking Rob this. One of the most important things is to not damage or kink the hard lines on the frame under the body. You have to lift the body to replace them.

He sells ours. I can give you technical advice on installing/ orientation.

I find different opinions from multiple people can be helpful. Plus in any conversation we may have missed something in going over the installation procedure. Anyway I have already discussed it wit Rob. Stop being such a pain in the ass David if you can't offer anything helpful.

Thanks Josh that would be great.

Don't question the guru. He has a mustache.

Seems like a lot of extra work to change the lines in the engine compartment.

If you got advice from Rob you are good to go. He is the authority on the parts he sells and there will be little else anyone could add. If you go around asking for more information you will just wind up confusing yourself. Besides, I did mention how you must be careful with your hard lines so I did have something helpful to add. You want more helpful? Use flare tool wrenches. They grab on more than just 2 flats and are less likely to slip and round off the fittings. Always back-up the fittings with a back-up wrench so you don't twist or kink the lines. Is that what you are looking for in the way of advice?

Splendid David, Thanks.

Chris,

I'm in the middle of having my intake off, so while I am not doing the exact same job as you (new fuel lines), I am doing some similar aspects (disconnecting at least half of them).

New copper seal washers seems like everyone is in agreement on.

The cylinder fuel lines (and others) are only torqued down to 7 ft lb. While this is good info for installing your new ones, I found it useful for removal too. Why? Because it gave me some confidence with how much force it would feel like taking to get each hollow bolt free initially. And not from a scientific point of view, just one relative to "holy crap do I ever need to lean hard on this rusty seatbelt bolt" type experience feeling.

7 ft lb is not a lot, so getting them loose should not take much effort. I did find it helpful and advantageous to really focus on getting your socket and ratchet well centred over the fitting so there isn't any cross force. You know what I mean? Get anything that might interfere out of the way (wiring harness, cable ties, whatever), get a good pair of gloves on and visualize where the handle end of your ratchet will go when it gives way and comes loose. That helps you save the skin on your knuckles and also gives you a better chance to get them off nice and clean without feeling hesitant. I found that anyway, you might too.

Other than that, remove them after your car has sat for a while to let any fuel pressure dissipate. Press down on the air plate to relieve any extra. There will still be some fuel dripping out of the hoses when you disconnect them, so keep some shop towels handy or have an assistant hold them under the hose for you.

And disconnect the battery just as a safety precaution too before you get started.

Thanks Jonathan that's very helpful. The biggest problem I have at the moment is getting the return line off from the metal line. It absolutely will not budge. I'm afraid to push it too hard. The union itself will spin both fittings but it will not break loose. I soaked it down with PB nut buster again tonight but I don't think it's going to go. Other than that it's tedious but I got the passage side injectors done already and I picked up new injector seals because I have no idea when they were done last if ever.

Any advice on how to get that return line off the metal line would be EXTREMELY appreciated.

You're probably not going to like this answer, but I ended up having to use a pipe cutter to cut the fittings off of the pipe. There's enough pipe to do this two or three times, so it's not the end of the world.

I cut the fitting off, and ordered new fittings from DMC-MW. Putting it back together was cake simple at that point.

Success! They're done. I finally got the return line off. Thankfully without cutting or breaking it. The carbon fiber colored lines look great and fit perfectly. Thanks for the advice everyone. Every little bit helps.
