Fuel Line Fuel hose - Quality, Makers, Sizes FAQ

the hoses from the tank to the filter, then pump then rail then the return from the FPR to the tank are done. The Gates Barricade line fit fine. The original VW clamps seem Ok but were a bit hard to work with. I reused the old external sleeve which was hard to slide over the fatter hose because the casing was bent. A new piece of casing would have been fine. I cut open the old hose. The braided line was shiny and looked very good inside. The NBR high pressure line looked good but it had a small amount of swelling and matte finsih on the inside so yes, the alcohol is slowly attacking that. Once the injectors are done and everything tightened down I will add fuel back to the tank and see if there are any leaks. The easiest clamp to work with was a replacement one with the correct rounded edges from Scott at German Supply. It had plenty of room still to tighten on the hose. Fuel filter was fine inside when I cut it open.

Finished the fuel line replacement last night and everything fit fine. Only caveat I would suggest is that on an FI bay, plan the line replacement around other things that require engine removal. What a PITA while the engine is in the car. I'm standing on a small ladder hanging down into the hatch working on hoses that I can't get to easily through the rear engine door. I'll let you know in a day or two if there are any leaks.

I'm sure it's been said in here, but I will repeat the braided cloth german stuff is Junk. I had some last less than 12months before weeping thru the jacket in my glass buggy. Not in direct sunlight or anything, just gave up the ghost. Car was garaged mostly, hardly driven. Also had it last maybe 18months in a beetle. I will never touch it again exept to use it as a vacuum line. I use FI lines for everything, but am looking for a good replacement that is cheaper.

Probably better safe than sorry... I did not install braided line this time.

there was nothing wrong with the 3 year old braided conti that came out HOWEVER the new line leaks far less by design than the older NBR fuel lines. As I recall Gates Barricade is less than 1 gram per square meter of line per day compared to 15 grams per day per square meter evaporating through the line for 30R9 hose and even higher on 30R7. There was always a slight fuel odor around my fuel lines that I could never figure out, quite faint. The bus is garaged so no wind gets to it. Now that odor is gone.

From my post on page 3: "time will tell"

Well after 8 months the news isn't good Crying or Very sad

Image may have been reduced in size. Click image to view fullscreen.

So apparently the metric hose from Advanced fluid solutions (silicone hose world on ebay uk) isn't that great Evil or Very Mad

Been running the Goodyear 30R7 hose in my bus since 2006. Hose is still pliable and no cracks.

So for those of us that run carbs, we do have to chose between line that doesn't fit, or line that might not stand up to fuel additives.

I am of the camp that replaces their Germain braided hose every year, rather than risk poorly fitting line causing a failure. Today marks the 1-year anniversary of my German Supply kit going in to my '69 and I'm about ready to replace the lines.

I read somewhere that German line is made in two styles, one with red lettering like the GS kit, and one with white lettering like the one here. I read last year on here (can't find the link now…) that the white letting is preferred. I picked this up from a FLAPS last week, and it has teh VW/Audi logo and "Made in Germany" stamped on it. I've seen no pictures of it on here recently.

It seems to have a fuzzier feel than the red-letterd GS kit line that my local mechanic also sells. ID measures a little over 5mm, but a little under 5.5mm. When I'm doing replacing it, I'll chop up my old line and take cross section picts of every fitting.

I cut open the old German line, no deterioration. I'll post picks and why I think that is when I'm back from my trip. Can't tend to the camp fire on my phone Smile

Well I'm not JUST getting back from my trip, but I just found the old line in my closet looking for a flywheel lock… I couldn't find the old pictures so I took these. This are after a year minus a few days of German braided line with red text.

Cross sections of two different segments:

Ends of section from fuel pump to carb, cut so I could remove it without ripping the carb fitting of. No damage otherwise:

From metal pass-thru line to fuel pump:

All the rubber innards of all my lines looked great. I haven't swapped the line from tank to filter yet; it's caped off while my engine is out. I don't have a big enough can to drain all of it yet. The frayed ends are from my small pliers to get the hose off because it acts like a finger trap when you pull.

I think my lines lasted so well is that I never let my bus sit for more than a few days. I constantly drove it, and ran out of gas a few times. I think this kept the tank fresh and the constant flow instead of sitting in storage probably didn't hurt.

This is the line that I got from German Supply in a kit. Good stuff.
