    It seems silly to the uninitiated (they say; "It's only a damned fuel hose!") but part of the secret to not having your e34 go up in flames one day is using all OE parts (with very careful installation) in this particular area. Migth as well do the other flexible hoses along the rest of the way to the tank also; 20 odd BMW clamps and a couple of metres of (the right) hose seems like good insurance to me... Please be sure to post some pics so we can all see how you went and learn from your experience... Nick

    Oh yea, and clean your engine bay up a tad bro!

Simply take off the fuel line at the front of the injector rail, put the T fitting in with the fuel gauge attached, and connect a new piece of fuel line to where every you unhooked. Idle the car, read the gauge. Get back to us. PS if your fuel pressure were too high the car would run like **** - it would run too rich.

    Make sure when you buy the hose it says "for fuel injected cars"
    Well I am thankful that I had read this far... I bought a line a while ago and installed it past the fuel pressure regulator. It did not burst and is quite fine now but I'll keep this information in mind...

    The OEM clamps for that particular application will be the "one time use" type, if I recall correctly. You could try finding a part number for a generic BMW clamp, or use the one time use ones if you're sure that the replacement fuel hose is the correct line (or if you have the socket to reuse the one time use clamps).

    There's a reason why the replacement parts for that section are sold as a kit, at $20 or whatever it is. The dealer or BMA would be where I'd get it.

    By the way, somebody's rewrapped the car's engine bay harness -- why?

    best, whit

    I mentioned this earlier - I want to stress this again - regular small clamps are good too so long as one wraps rubber sheet under the clamp. This increases the diameter minimizing the effect of bad compression at the edges of clamp base.

    I lost my e30 to use of improper fuel line before I learned the difference the hard way. My ex-FIL replaced a leaking section of fuel line..."fuel line is fuel line..." it worked fine for about a month. Then one day it didn't, poof! Not a pretty sight watching your car burn.

    Don't take chances with this stuff, it doesn't happen often but it does happen.

    I had a starting problem a while ago, and I had it towed. before I struggled 2 weeks with it. It was a pick up sensor, or rather, crank sensor or something. neways, before they found that out, the replaced my coil. and the coil the put in was damaged. so it burnt out all the wires, everything went up in smoke. *that was quite a sight*. so the shop got some auto-electrician to come fix it up. but he rewired my ignition wrong. so now i'm stuck with ignition(off,on,start). no more listening to the radio without everything else in the car turning on.

    Ok, I went to get some BMW hose, and fitted it to my car. The BMW hose is much tougher than the dodgy store baught hose. I also noticed tho, that when I removed the fuel pump fueses, and started the car. that the pressure went away on the pipe. now when I reffited the new pipe. the pressure does not return.

    Is my car BMW Biased or something...

    neways, I think there was maybe just pressure buildup there, I don't know why. I've never removed the fuses and cranked it, when I replaced this pipe. so maybe that did the trick.

    hope someone else has learnt something from this aswell..

    NEVER USE ANTI-BMW HOSE !!!, your car might just blow up.
    no kidding.
