+1, I installed Roger's kit back in July 2007 on my GT, still going strong. Tough to beat at half the cost of one of GB's lines.

Man, I am so sorry to see those pics. Same thing happened to mine while it was in the garage just about a year ago. Mine was an 88s4 white/lipstick red. The fire started just about 2 minutes after I had it running perfectlly. I bought myself an 86.5 project and have just finished rebuilding the engine. I still believe these are the best cars in the world. Sh#!! Hapenes to good people.

I'm not saying that what I make and sell is for everyone, but I personally won't install a hose with a clamp, where there was originally a crimped hose.

I figure that if Porsche thought that was the correct way to do it, they would have installed hoses with hose clamps from the factory....it would have been way cheaper for them to do it this way. Note that the only fuel hose, in a stock vehicle, with clamps is the "suction" hose that runs between the tank and the pump.

Suction hose.

Only one with clamps.

You think you are smarter than Porsche?

Clamp away.

A bunch more of these 928s need to get destroyed for them to become uber expensive, anyway. Fire works good at destroying cars.

Clamp away.

I'll pass, thank you.

The hose I use is Goodridge 210 series. "Integral stainless steel reinforced synthetic rubber with lightweight fibre (they are British) braid. 500 lbs working pressure, 2000 pounds burst pressure. I personally pressure test each and every hose at over 500psi for two minutes, on my pressure tester, before they leave here.

The end fittings are what make these hoses so expensive...the hose is actually only $7.00 per foot. Metric fittings are amazingly rare...even though I keep complaining at every meeting with Goodridge that they need to build their own....they actually source these fittings from another company. [Goodridge insists on making "new" fittings that are still AN (there's another entire new "series" of fittings and hose coming out), even though almost the entire world has gone metric.] The 90 degree end fittings we get are $60.00 each. The straights are cheap, but those hoses at the rear of the engine need 90 degree fittings, on both ends. The end fittings disassemble, allowing the hose section to be able to be replaced, virtually forever, which makes their cost better, over the long run, but they are expensive the first time they are purchased.

I personally dislike the stock pressure line that runs over the top of the valve cover to the front damper. For while, I re-used the metal portion of those lines and made a replacement hose section, however I found that finding decent steel portions was becomming very hard. Seems like almost every line was "crimped" from someone bending it to remove the valve cover or rusty where the rubber insulated clamp secures it onto the water crossover. I now make a complete hose that replaces this entire assembly. It no longer goes over the top of the valve cover....I've completely re-routed this hose, around the front, where it seems like it belongs.

I'm working on having metric fittings made, for use with our PTFE lined hose...which is virtually indestructable, unless you physically crush and bend the hose back on itself. These fittings and hose will probably be "crimp" style....that is one of the final "issues" that needs to be determined. Still a long ways off...this stuff take unimaginable amounts of money to custom make, requires relatively large initial quantites for an production run, and then takes unimaginable amounts of time to get produced.

It took me over a year to get the little 90 degree elbow fittings that fit on the CIS Injectors and fuel distributors made....and to be able to do this, I had to order 1,000 pieces, before they would build the first one. Since I've started into the "hose" business, I've had about 15 custom ends or adaptors made....and each one has to be ordered, like this.

Crazy amounts of money invested.

I wouldnt put them in the same category, casually speaking.

They are not.

I would have to say that Greg's braided lines are the best ! I bought his fuel line at 928intl and installed on mine and i wish i had not bought other fuel lines from Porsche. The orig kit that i bought from another vendor ,the line started to crack at the bend. Thanks Greg.

Rob Edwards

I think Greg's hoses are the best solution available, no question. I didn't know about Greg's hose business in 2007 or perhaps I would have done a set then. (In fact I'd not yet met Greg at that point..) But Roger's kit has held up fine.


Just for posterity, here's all the GB fuel line bits, in one place:


Rear fuel U line and return line, an 'old style' rebuilt fuel inlet line, and oil cooler lines:



More rear U and return line, in situ:












The 'new' fuel supply line:

Fuel pump to rear wheelwell supply line:

I have a set of GB hoses for my car, since last year and have not had time to put all of them on, sad really.
I have new hoses from Porsche on it that are about five years old, and they need to be replaced.

Glad everyone is ok, it is a same about your car.

Über such man. glad everyone is OK

Sorry to hear about the fire. Sad when one of these cars burns. Even sadder for me as it looks like it was a burgundy or cassisrot.

It sounds like this was not an engine hose fire, but no one can be sure now. From the location of the flames, it does look near the firewall.

As for crimped fuel hoses, many(most) car mfg use them all the time. Ford, GM, Audi, VW, Peugeot, Ferrari, Fiat, etc. It's pretty common on FI systems. The problem is not the crimp, but the age. No hose is designed to last 24 years with no mx. I would say the life of the rubber hoses and the crimped connectors is about 8-10 years depending on fuel used, and heat. Alcohol additives and some winter additives to fuel is hard on hose that was not made for that compound.

Every car over 10 years old should have it's fuel hoses replaced regardless of crimp or compression fitting. I felt pretty ill driving my 86 a few years back knowing the hoses hadn't been replaced. It's one of the first jobs I did, and I would never sell a vintage car without replacing the fuel hoses en masse.

For anyone who's curious, Roger has a long engineering history with pressure hoses, fittings and materials. I'm an EE and I trust his judgement that the crimped kit will work for 8-10 years if installed properly. The kits have been out there for quite a while and so far 100% success. They are rated for Ethanol fuels, and the rated pressures are far above what the pump will put out even in the case of a blocked return or damaged regulator.

Hmmm you guys may be on to something but lets not blow it out of proportion.
If we start condemning everything aftermarket that we "need" we will be SOL, and Roger will drink to much wine

On the other hand we do not want anyone to get hurt, or worse.

I would recommend that the car be inspected by 1 or 2 of who ever is closest and qualified to see if it happened in the suspect area.

I could not fine a suitable way to make the line from the passenger fender so I cut the old one and modified it to work.
I could not find the correct fitting for the car side fuel line on the fender

Doc - I think you meant "clamped" instead of "crimped"? Or is there a crimped kit too? BTW - Your qualification as an EE will be immediately dismissed if you're an aggie.

docmirror

Yup, clamped. Not an Aggie, UCLA for most of it.

Did you ever check out your FPR and Damper? I once removed the vacuum line from the transmission and got doused with fuel... Could have been fuel dumping from the vacuum line where it attaches to the hard line right by the flywheel... the fuel could easily run down the line and soak the foam in the tunnel...
