G'day!
So I need to replace the fuel lines on my 05 E. I spent a substantial amount of time reading the debates here about 1/4" and 5/16" hoses, as well as looking for somewhere to buy OEM hoses.
I ended up running down to the local hydraulics/hose place and explained the problem. Now I'm sure someone has thought of this before, I just haven't seen it written here. I felt like a bit of a nufty when they produced three 8-10mm hose adaptors with three lengths each of 8mm and 10mm ID fuel hose.
I'm yet to put it all together but this seems like an incredibly easy fix to get around the problems of 1/4" being too small for the petcock and 5/16" being to big (ID and OD) for the tank and carbs.
Hose being too thick wall will prevent it from fitting at the tank. I know, I cant get radiator hose on at the tank.
Cool.

I've tried several different sizes and kinds of fuel approved hoses over the years (and several kinds of clamps too) and my preference is definitely OEM. It was sooooo easy compared to anything else I've worked with.

OEM is always a good choice. That said I decided to take a chance and try the Motion Pro clear premium fuel line. Also went back & forth on the size and decided on the 1/4". Looking at the original lines, they appear to be 1/4" and they just stretched one end at the factory. From what I've been able to research, these clear fuel lines are good for stretching.
My original clips are in good condition, but just to be safe I ordered the Drag Specialties assorted set.
I'll probably be installing it in the next few days. I'll let you know how I get on.
I finally got the rebuild kit and parts for the petcock. Here is the completed assembly using the Motion Pro 1/4" premium fuel line, K&N sintered bronze filter, and Cadna 1/4" fuel injection hose.
I had to pre-stretch the clear line to make it fit (pushed it onto the tip of my long nose pliers). Even then it was quite difficult to push on. A dab of synthetic grease really helped. Warming it up with a blow drier also helps but make sure it doesn't get hotter than what your fingers can stand. Other than the stretching, there are no signs of stress. This seems like really tough stuff. With time I hope the line stays stretched to make it easier to re&re. You can put quite a bend in it, and it doesn't kink.

Well I put everything back together, and the petcock started leaking right away. I had to take it all apart to diagnose the problem.
The fuel lines were
very 'grippy' and difficult to remove even though they had stretched a bit. It was way more trouble than it's worth. It was also very difficult to see if there was any fuel in the lines, so the transparency is of little or no use.
I'm considering this experiment a failure. If anyone else wants to try it, use the 5/16" ID hose. The 1/4" will definitely not work.
I'll be reinstalling the original lines, but may keep the new outlet with the filter. Or cut the original line and insert the filter there. Haven't decided yet.
I'm going to be buying OEM lines if I can find it. These silicone/tygon whatever crap lines are a PITA to get off.
But availability is a question as always.
Cool.

The strange thing is it was almost harder to get it off the tank outlets which are 1/4"! I had to pull so hard the RES outlet came right off the petcock. Fortunately I gently hammered it back in and all seems fine. Looks like simple press fit.
I put the original tank lines back in. But kept the Motion Pro line from the petcock to fuel filter. Originally I used just a dab of grease to help get the line on. But this time I went nuts and it really made a difference. I wouldn't say removing the line is easy, but the grease makes it doable. I'm using Finish Line synthetic grease which is designed for bicycles.
Maybe I should start looking for those OEM lines now, so I have them on hand
I hope to find the petcock rebuild kit (rather I hope the one I ordered off ebay works)
I didn't get the lines yesterday when I was at the motorcycle shop. I have a ton of this tygon bs, I might just use them. Once you break the seal all around with a pick or similar tool, they do come off fine.
Cool.
