Guys I'm trying to replace the fuel pump. I can't seem to get the high pressure hose undone. I've bent the pipe a little in trying and now I seem to be just rounding off the nut on the end. I'm using a flare wrench.
Does anyone have a secret on how to get this off without damaging that pipe and if I was to damage it what would I need to do to effect a repair?
I don't know for sure, but I suspect you're trying to turn a nut that is soldered to the hard pipe.. You need to disconnect the hose at the other end,(under the car) and then spin the hose off of the pump end.

At very high boost levels. 42-44psi. There are some crazy people out there, and those Supra and Mitsubishi guys are some of the craziest. Patrick"
yup, i JUST did the same thing like two weeks ago.. and had to run a soft line clamped down with two of those little clamps where you use the wrench.
if you haven't twisted that hardline up too bad, do what these cats are saying,but if you have (like i did...) then you could probably do it like i did it. let me know if you need more instruction.

It is not sodered to the hard line IIRC. They just like to rust together making it a complete bitch to break loose.
i replaced it a while ago as well, but that hard pipe loosens at the other end, i didnt do anything under the car, there's the end that connects to the top of the cap, at the other end you can unscrew the pipe. something was wrong with mine after i removed it so i got a "soft line" like that other guy. that is way much easier

I had another go and I may have put too much of a restriction on it now. Did you just cut the hard pipe? and then just put a bit of ordinary fuel line in there with the screw type clamps?
What sort of pressure have we got going through there? am I likely to get a leak if I do that? because I can't see me getting it off any other way.
I'll jack up the car tomorrow and have a look at disconnecting it at the other end but I think I'll probably have the same sort of problem.
Remove the high-pressure, fuel line. This is at the end of the metal pipe coming out of the assembly. It looks like there are two nuts there (or a bolt and a nut). The "bolt" is fixed to the metal pipe and does not turn. The "nut" is attached to the rubber hose. Attach a 14-mm flare-nut wrench (an open-end wrench will do) to the fixed bolt on the metal pipe. Use a 19-mm open-end wrench to loosen the nut on the hose by pushing (or pulling) the wrench toward the outside (passenger-side) of the car. Make sure that the "bolt" and metal pipe do not move or bend. I found it easier to work inside the compartment with a foot on the 14-mm flare-nut wrench. Once the nut is loose, you may be able to remove it completely by twisting the rubber hose many times. However, it will be easier to loosen the fitting at the other end of that hose in front of and above the gas tank. Here is where it is helpful if the car is raised. Both pieces spin on the fitting at the front of the hose. Loosen the fitting using the 19-mm wrench on the hose "nut" and the 14-mm wrench on the metal pipe "bolt". The bolt rotates counterclockwise and the nut clockwise, as you are laying on your back, head towards front of car, looking up at the fitting. It is not necessary to disconnect this fitting; just loosen it. Be sure to wear glasses or safety goggles when working underneath the car.
NOTE:The last time I removed my fuel pump I found it easier to leave the high-pressure line attached to the pump assembly and to remove the forward end of the hose (near the front of the fuel tank). Then the hose is removed with the assembly. The assembly must be maneuvered a bit more than in the procedure described above.
Once you've soaked the fitting with penetrating oil, lightly tap it with a wrench to allow vibration to help the oil get into the threads of the joint. Let it sit for 5 minutes or so.
Put your 14mm flare nut wrench on the rearward side of the fitting and then put your 19mm open-ended wrench on the foreward facing side of the fitting. Keep in mind, that it's the hose-side of the fitting that will move, not the pump-side. If you position the wrenches as shown in the picture, you can simply wrap both of your hands around the wrenches and squeeze them together. Assuming you break the connection free, move on to the next step. If not, keep trying, or enlist the help of your muscle-bound neighbor. This is likely to be the hardest part of the whole process. You can do it.
