Ok. Thank you!

Can you post a pic of the 2 hoses u have made? I always wondered about the plastic fuel hose and wondered what to do about replacing it....thanks

James Bailey

Greg did take some pictures of the new fuel lines before he installed them and did keep the old ones as samples for future use as he makes more lines. Maybe he will post them on this thread. His attention to detail and precision still amazes me ! one thing we did was bypass the heater core so he turned up a alloy insert with a small hole for an air bleed smoothed and finished then put it inside the hose where it would never be seen again That was to restrict the water flow since it bypasses the radiator ! Yes he thinks about such things.

I have a pic of the S4 and newer regulator to damper hose:

Yes the hoses and fittings are really nice !! And have all the correct connections and attachments.

I don't know if i am missing something, I was wondering about the plastic fuel line on right side of engine bay, passenger side, near from of engine near eyelet lift hoist. It is the high pressure incoming fuel line that is curved very sharp curve then connects to metal pipe then goes to front accumulator/damper.......

I assume this line is barbed underneath I don't know....I have to remove it to pull engine anyway.....

James Bailey

The different models use different hoses some S-4 have a mix of rubber and plastic. Maybe Greg will post some photos of different years and the proper way to replace....newworld, if you add the year of your car we can get more specific.

My '84 Euro only has one fuel line on the right side of the engine bay???

The later cars use a fuel chiller on the firewall (apt name for the location) It borrows some cold from the A/C system so lowers the temperature of the excess fuel being returned to the fuel tank to limit boiling and cavitation near the fuel pump.... so more fuel lines to be concerned about under the aircleaner base.

Yes, what would be the ultimate is a list of hose types (lined vs. rubber), by year. And pictures of each would be awesome.

I put a hose “kit” on my 86 and had concerns of rubber replacing lined. In my opinion, the old “cracked” hose with lining was better than the new rubber replacement. One in particular I was going to put back on until my brother cut it open to see what was inside.

I would spend good money on good hoses, but first I’d like to know more about them.

100% agree. Porsche could have certainly specified rubber hose, if they thought it would have worked, properly. All of the 911 Carrera models, through 1989, had rubber lines with very high tech crimps. These were attached to the proper metal pieces and not onto metal fittings with "barbs" (for plastic hose).

They leaked like sprinklers, once the hose started shrinking, and Porsche superceeded the style of crimp to a double crimp style. Lots of these cars burned, also.

Greg,

I don’t see mention of fuel hoses on your web site.

If we want some do we purchase from you or go through a vendor? Are these on the shelf or made to order? Is there standard pricing?

I’d be curious to know what the cost would be to do my ’82 and ’86.5.

My website isn't up to date. Only so many hours, in the day.

Interesting thing about me. I get more joy out of inventing and making stuff than selling it....so I'm hardly ever selling and always inventing.

Roger has inventory on some of my fuel hoses, but certainly not these, yet. He mostly sells the "cheaper" rubber hose and hose clamps. I can't seem to convince him that he shouldn't be selling that Gates Barricade hose to go onto barbed fittings, made for plastic line. That would seem to be a liability "nightmare", to me (since Gates tells you specifically not to do this).....but I'm certainly not an expert on liability concerns....and he is certainly a big boy.

I do have all the different fuel hose versions in stock. The '85/'86/early '87 with the fuel regulator that has the clamp on return line are especially a "taxing" issue. Running that clamped rubber hose under the bellcrank and then over to a connector that has crimped fittings on it always seemed so silly, to me. Way too many potential places to leak, with two different styles of hose....all ancient, by now. I'm really happy when people get Porken's chips and update the regulator to one that has a threaded on connnector, so I can run one high quality line from the regulator to the fuel cooler.

I'll get some pictures, prices, and post them here, this week.

This is a very interesting and informative write-up on using push-lock fittings and aeroquip push-lock hose. http://www.arnnworx.com/fuel_lines.htm.

The same guy sells push-lock fittings with the globe seals used on our cars. He also sells the aeroquip push lock hose. I don't know if the aeroquip is as methanol resistant as the Gates hose a lot of people are using but the aeroquip is built to be used on aggressive barbs and is not intended to be clamped.

Prices for the fittings are reasonable, but going his route would require using his compression fittings on the hard lines because the 3/8 I.D. aeroquip hose is not a tight fit on the existing barbs or hard lines in our cars.

Here is a link to his stuff: http://www.arnnworx.com/fuel_lines.htm

Great quote from that site ...."The more I learned about this stuff, the more I realized how little I know. Even if you find the perfect combination of parts, there are still potential problems. For instance, Porsche recalled thousands of the jumper lines (seen above) for poorly crimped fittings. The only point here is that even professionally prepared hose/fitting connections are subject to problems.

All of the above brought me to the idea that I should seek out a professional. So I set out to get a pair of fuel lines made up at a local hydraulic shop. The guys there took one look at what I wanted and said "thanks but no thanks." ........

Good news is Greg has it all figured out and knows how to make the connections !!!
