The hoses above are some that i have put on customers cars from Greg.


These are some cooler lines that I had a not so local company make up for me here in Atlanta, not easy to get these cooler lines on and off, i finally solved the problem on the third try, from then on i got the lines from Greg.



One of the lines off of my car.

 

Sharktoberfest has passed, so the hoses are no longer on sale.....

So, as promised:

I think the best thing is to identify what hose ends you can use rubber and clamps on...and what hose ends you need to call your insurance agent and get a declared value policy.

This is a barbed hose end, with the original plastic hose removed. Those sharp barbs will cut soft rubber hose, especially when forced tightly onto the barbs with a clamp. I would never install a rubber hose with a clamp onto this style hose end. Very few, if any, hose manufacturers would suggest it, either. To clamp a rubber lined hose onto this fitting is like praying for a fuel fire, as far as I'm concerned.




This is a fitting that is made for rubber hose. Note that it is smooth and when clamped, the rubber hose will not cut the hose. The very end is like a "barb", but is very smooth and is designed so that the hose can not possibly slip off this fitting when clamped. You can/should use rubber hose with clamps, on this style fitting.



These are some of the "Porsche" hose fittings that made replacing fuel lines with the "proper" hose very difficult. All of these ends have "barbs" under the plastic line. Since no companies made adaptors to fit these, many people were "forced" to use rubber hose and clamps to attach to these ends. Personally, I'd rather hope that the original plastic hose that attached to these kept working, than attach rubber hose and clamps. Note the "end pieces" on this hose. They are not crimps, but simply "protectors" for the end of the rubber that covers the plastic line. If you have this style "end piece", you have fuel line with plastic hose, under that protective rubber covering.



Here's a picture of some of the custom adaptors that I have had made....just to solve this "fuel line problem". These adaptors are metric and made for the Porsche fuel fititngs on one end. The other end is standard "AN". All adaptors are $17.50 each, so if you want to make your own "AN" fuel lines....you can buy just the adaptors. Note that there are both convex and concave versions in the male adaptors. Porsceh used both. I don't mind if someone wants to make up their own hoses to save a few bucks....just don't install rubber hose onto barbed fittings!

 

Great stuff Greg, thank you.

I still anticipate more on which hoses you have available and their price.

My 86 has a rubber “kit” which I am not really comfortable with and my 82 has “who knows what”. I would love to go with everything I can get from you, if I can afford it.

I’m keeping an eye on this thread.

Thanks again,

Denny

 

Greg, thanks very much for this detailed information, and that is an outstanding offer on the fittings!

 

Greg, a dumb question. If the Porsche fuel fittings are metric, why not make an all metric fuel line instead of using custom metric/AN adapters with an AN fuel line?

 

At the rate I move, the Sharktoberfest "sale" is probably going to be a Thanksgiving Day Sale....

Here are the hoses for '85/'86 USA models.


This is the hose that runs from the front damper to the fuel rail. It is still available, from Porsche for about $50.00, in limited quantities. My replacement hose is $125. On sale for $110, until Thanksgiving. I'm not getting "rich" selling this hose....that price is purely indicitive of what it costs to have the metric fittings made, get them shipped here, and installing a high quality Teflon lined hose onto them....in small enough quantities to make it feasible to do. (I normally stock the stock Porsche hose, too.)




Front fuel pressure hose. Replaces the entire steel/plastic fuel line assembly. $160.00, on sale for $145.00 until Thanksgiving.




Fuel hose from rear damper to regulator. $165.00, on sale for $150.00, until Thanksgiving.




Rear of engine return line to fuel cooler. $135.00, on sale for $120.00, until Thanksgiving.



If you still have a regulator that has a rubber hose which runs from the regulator to the "junction" on the top of the valley area, in the rear, you can replace that hose with the "proper" German fuel line and clamps. Cost is about $15.00.

If you have replaced your regulator with a regulator with a "threaded" connection, like the mid '87 to '95 regulator (Porken performance chips use the later regulator), I have a fuel hose that will go from the regulator directly to the fuel cooler and you can remove and discard the "junction" piece. (This converts the return line to a one piece line.) This one piece hose is $155.00, also on sale, until Thanksgiving for $140.00.




Complete '85/'86 front fuel line, with original design fuel pressure regulator. Includes stock German hose and clamps from regulator to "junction block" (not pictured). On sale for $500, until Thanksgiving.



Rear hoses installed. Note "rerouting" of hoses.



Two hoses, front of engine, installed. Functional, safe, and pretty too!

 

for this fuel hose, front right, i assume this nut does come out to disconnect this fuel line? i cant budge it used 17mm and 19mm to counteract on either side, but it wont budge.....

this connection seems fused, sprayed liberally with penetrating fluid, but i cant get it to budge!

 

Make sure you are trying to turn the smaller nut on the right side of your pic (over the metal pipe) while holding the larger nut on the left side (over the rubber hose) stationary. Here is what it looks like when removed (and in my case showing the scars of my efforts):



You can see I had a bit of corrosion in the threads.

 

Yes the male nut on the metal pipe does turn on the pipe and will screw out of the female nut. keep soaking and use long handle wrench's (flair nut if you have a set that large) yes 17mm and 19mm IIRC.

 

ok i need to get a 17mm flare nut wrench, my flare wrenches max out at 15mm

 

These should be good for another 20-30K right

 

Good to see people checking the fuel lines and avoiding some grief. Also if you do have a fire be very carefull when you open the hood since the V of the v-8 can hold lots of fuel and with extra air it flairs up, one customer lost eyebrows and had serious burns on his hands and face.....true story; end of an S-4.

 

Do you have the lines for a 79 CIS car?

A pic and how much would be greatly appreciated.

 

Hello Greg,
These hoses look fantastic and should be the last hoses I'd ever have to buy. I'd like to purchase 4 of your front engine fuel supply hoses (from fuel supply line to front pressure damper). These are to fit an '85, '87 (early VIN), '87 (late VIN), and an '88. I prefer the all rubber hose rather than fitting to the existing steel line with short hose at the end. I also have the two hoses you gave me at SF12 I'd like to settle up on. There may be a few more hoses I'm interested in after taking a look at the rear of the engine compartment. I'm off work during the week of Thanksgiving so should be able to drive down to your place to pick up the hoses - if it's convenient. Please PM if you need any additional information. THANKS for the great work on these hoses!

 

PM sent.

Those hoses look amazing.
