So while I was installing my Walbro 190 fuel pump today, I accidentally ended tearing the hose with the flare fittings on top of the sending unit. The hose tore completely off of the fitting. My question is does anybody know of a place where I can get a new hose like this, besides from a part out ad or a junk yard? I've looked at my local parts stores as well as rock auto, extremepsi, and oemmitsubishiparts and can't seem to find this specific hose.

Or does anybody know of a homemade way I can solve the problem if I can't get a new one? Or maybe a place that can make me a new line like this?

I actually had to cut the hard lines on top of the sending unit to pull the assembly out to put in my 255. I just used the fuel line hose from advance and hose clamps from the tank to the pump. I'm not sure what size I got, but just compare it to the old lines. Hope this helps.
 
Thats what I'm thinking of doing. I just don't know if a hose and a clamp is gonna be enough to hold the pressure. Did you have any leaks when you did that?[DOUBLEPOST=1411149677][/DOUBLEPOST]Also I went to napa and car quest where they can make hydraulic hoses, but it seems like nobody has the right metric fittings to do so, which doesn't surprise me
 
Its been several years since I replaced that hose on my car, but I just picked one up from the local mitsu dealer. Eventually just replaced the whole line from the pump to rail with a kit from STM.
 
Well if it shouldn't leak then I'm going to give that a try. I'll let you guys know how this turns out.

And I wish I could go to a dealer but the nearest Mitsu one is about 30 miles away and well I don't have a car at the moment to drive there. I doubt that they would even have that hose there anymore though. It seems like thats a common theme on my car
 
Well I think I have the hose issue figured due to some custom-made fittings. I attached everything back to the car and tested it out and low and behold one of the hard lines on top of the sending unit is cracked and was pissing fuel everywhere. I've been contemplating getting a bung welded on there but I'm not sure if its even weldable since that metal plate is so thin. I would try to cut the broken line and flare the end and attach the hose there, but the crack is too far down on the line.

Any suggestions on how to repair or attach a new line or what kind of weld should be used to weld on a bung? We have a mig wire welder, and I'm not sure that it would make good seal with over 40 psi of fuel going through it.

As long as you get fuel line grade rubber hose, and a decent hose clamp, shouldn't leak!

Its a very bad idea to use auto parts store fuel line and hose clamps on pressurized fuel line , the regular bulk fuel line you buy the foot at most auto parts stores is only rated at 30-50psi. There is special hose and fuel injection hose clamps that are different but its a much better idea to get lines with the proper fittings or convert to an fittings.[DOUBLEPOST=1411245922][/DOUBLEPOST]

Every parts store sells fuel injection hose which is good for 180 psi. They also sell fuel injection hose clamps. There are a lot of cars that use fuel injection hose and clamps from the factory. If done properly there is nothing wrong with it.

People are suggesting to go to the auto part store and get "some fuel line and good hose clamps" if you walk into most auto parts stores and ask for a 2ft of fuel line and some clamps you not usually going to get the correct stuff unless you specify that you need fuel injection hose and clamps. Not everyone reading these threads knows that so I am just to trying to clarify that not all fuel line and hose clamps are equal and you need to get the right kind.

Yeah I've seen this thread and really like the idea and it seems easy enough to do. I'm just a welding noob and I don't know if our mig wire welder will be good enough for this or if a different type of weld would be better. Could someone point me in the right direction here as far as the welding goes?

Depends on the parts store, every time i go in they specifically ask what is needed.
 
Also I made sure when I went to NAPA I got the correct fuel injection hose. I can compare it to another piece of fuel hose I had laying around rated for 3.4bar (~50psi) and its much stiffer.
 
I've never checked the pressure rating of the pre-packaged hose, but they always have some all sorts of line in the back that you have to ask for. The pressure rating of the hose and what it's good for (ie. fuel, oil, etc) should be stamped on the hose itself, so you know exactly what you're getting. The clamps you need look basically like mini T-bolt clamps. As long as you have a bead on the line, it should be ok.
 
I had to cut my hardline and use a hose an clamps they worked great I grabbed some from napa for the fuel so It didn't cut into the fuel hose, its about two inch fuel hose which worked great until I a larger fuel line from tank to the new aeromotive fuel filter coming.
 
Well as far as the torn rubber fuel hose goes, it's been fixed with some custom fitting my father was able to make for me at his work (he's a machinist). One end of the coupler has the M14x1.5 threads that come from the hard line off of the sending unit and the other end has just typical, more common threads that a hose barb is threaded into (with lots of thread tape) and then the fuel injection hose double clamped onto the barb. So far no leaks.

For the cracked hardline we were actually able to braze over the crack using a MAP/Oxygen torch combo and a brazing rod. Then the braze was covered in JB Weld just for the extra caution. No leaks so far.
