Best way to disconnect the fuel lines?

[Max777]

Umm, yeah, what's the best way to disconnect the fuel lines from the engine withought making a huge mess?

I'm about to pull my old one out as soon as the stand adaptor comes in, and I'm a bit worried about this, like burning my house down and all. I heard I need to plug them up or soemthing? Haynes just says "disconnect the fuel line" and that's it.

Anyone want to chime in? This could be a great searchable thread for the future!

I don't do anything special except for the usually precautions when dealing with flammable liquids - no smoking, no sparks, remove all sources of ignition, etc.

I just had a couple of rags handy to soak up as much of the spilled gas as possible.

Just have plenty shop rags on hand to soak up the fuel thats all I do.

I usually forgo the rags even. If the fuel isn't going to get on anything painted I usually don't worry about it. But that's just me. I do sometimes cut fuel while it's running when I know I need to work on it so there won't be as much fuel in the lines. You should try to keep the mess down, but whatever.

[Max777]

ok....

so do i need to plug them?

Also, where can I get the fuel injection fuel line? And what size do I need? Thanks.

[Ender]

Oh, yeah, I'd recommend plugging all openings. However I usually only do if I'm going to leave them exposed for more than a couple hours, be stirring up any dust or crap that could fall in, or both. Parts stores will have fuel line. I think 5/16" line will replace the stock rubber lines.

I went to Autozone, and they had some, but it was MAD expensive, and was only sold in short lengths.

I was looking for like a spool of it.

Would this work?

Yep, they charge like $5+ PER FOOT locally here!
I think that's the same guys I've bought mines from off of eBay.
I've got no complaints!
And 5/16" is the correct size - it's like ~8.5mm in metric.

sae30r9 plug that into google im sure you'll find something cheap, i bought mine off of ebay.

[My5ABaby]

Sometimes I get it cheap and sometimes it's ridiculous. :dunno:

Anyways, I use my fuel cut switch and let the car turn off (you can also rev to 3000rpm and turn the car off). I let it sit for a while and then just pull the lines off. I try to keep them pointed vertical so all the gas stays in the line. I don't have the metal lines in the rats nest so those aren't an issue for me.

[Max777]

Well, I found some good info on the SAE30R9 hose:

NOTE: it also mentions only using SAE 30R10 hose for submersible applications, so for anyone reading this in the future, be shure to do that!

i don't get the problem. Rip off the old lines, go get new lines and you're done. You obviously need to make sure the fuel system is depressurized and don't have an open flame anywhere near you (includes water heaters in garage) but other than that it should be straight-forward (like vacuum lines).

[Max777]

Dude, I got it. Just posting up some useful info for people who need to do the same thing in the future. Dont get too excited! :D

[Phoenix7]

who's excited? Did you ever find a cheap source of fuel lines?

[Max777]

I thought tha $30 for 10 feet of it is pretty cheap, no?
