while removing my LIM i broke off the 2 omp lines that went to the injectors on the LIM itself.
does anyone know where i can buy replacement ones?
or is there another way to replace them, can i just buy new lines from the hardware store and replace them

You can buy new lines and replace them. I broke mine too while i was taking off my engine. i broke one of the line and i couldn't find anystore that have any line that would fit. so i just block it and premix.

Small engine fuel line works just fine. Small engine as in lawnmower, weedeater or you can buy some off McMaster Carr's site. See the archeives for this forum and there is a clear description on how to remove and replace the lines without buying them from Mazda for huge dollars.

yea, the mazda replacements are really expensive, i went with the Mcmaster Carr replacement method and it worked well. I ordered 8 feet of tube (Part no: 51805K32) which was about the minimum you should, just to make sure you have enough extra if you mess one up, and the 2-eared clamps worked well although if I were doing it again, i would get a size smaller (one size smaller than part no: 54105K34). The ones I have wont pull off, but they still can rotate on the banjo fitting. Its really pretty straightforward and easy.

so i can just go to the hardware store and buy some small engine fuel lines and that should work?
are they strong enough and heat resistant or whatever.
i was reading that archive post about OMP line replacement and they were discussing the hoses ability to handle pressure.

are small engine fuel lines strong enough?

well, none of those lines will see significant pressure unless all of them get clogged, so im not sure thats an issue. I wasnt sure about the heat resistance one way or the other on those lines, so i just went with the mcmaster lines to be safe, since they did have a temperature rating on the site.

One word:

Premix.

HAILERS

I almost wrote what I think about premix and the people who use it, but really don't want to cause another twenty page thread on omp and premix. So I decline.

I've been using small engine fuel line on turbo and not turbo for several years now. Bought it from a local hardware store. It's 1/4 OD and 1/8" ID. I've never seen the brand name. It was on a roll that you cut a piece off as long as you need. It has a part number/code 048643-125711 FUEL LINE on it.

There is nothing wrong with the McMaster Carr hose. I even bought ten feet or more, but decided to use the small fuel hose instead and leave the McMaster Carr stuff for another engine. IT is 3/16"OD and 1/8"ID.

The small engine fuel line is pliable but a bit larger OD from the McMaster Carr. Not a problem.

Cut the fittings off each end of your bad line. If you get a propane torch you can burn the plastic hose off the fittings and the *ear clamps* will fall off. Make sure the openings in the fittings don't get clogged. The ear clamps can be opened a bit using common sense and then installed over the new hose. Shove the hose on the fitting then pinch the ears on the ear clamps til tight. Or if you destroy the ear clamps, get some five minute epoxy and put it on the shaft of the fitting using care not to get any near the opening. Shove the hose on and let it set up for an hour or so. It will not leak and no epoxy can or will enter the hose or fitting as you shove the hose on the fitting. That's if you put the epoxy on the *shaft* of the fitting.

thats what i just got done doing.
i used the 1/4" fuel line from the hardware store.
decently snug fit.
being me, i also bought the wrong sized clamps, they were too small.
and having no ride back to the hardware store i tried to make it work.
and getting frustrated after failing horribly and getting hurt in the process
i decided to screw the clamps and left the hoses.
but now that you mentioned the epoxy, you think i could just put it on the ends of the hoses
or do i have to pull the hoses and re-do them
