Yes, because the motor needs fuel to run properly

 

Sean replaced mine a few weeks ago with Rogers kit... Top notch job and Nothing like peace of mind

 

One of the first things Sean did on my car several years ago ... if it weren't from him, Roger and Rennlist who knows what might have happened ...

 

...........we'd all be driving a Prius

Fuel lines are cheap insurance

 

Here is the after photo. No stinking hose clamps on these. Plumbed BETTER than factory ! Note the shielding cover.

 

Thanks to Roger, just had a full set of Greg's space-age fuel hoses installed on the rocket. Old hoses were replacements for the orginals and looked fine, but I didn't want to take any chances and went with the new ones.

As everyone says, the construction and design of the hoses (and fittings) are excellent!

 

I don't think Porsche intended for a lot of the parts to be changed on a 30 year or when it fails basis. These were flagship cars with an expectation of aggressive proactive maintenance.

 

If the factory one lasted 30 years, this will last 50 with the "shielding cover"
Is that something i can just buy from some hardware store? Is there a name of the material? Thanks

 

True enough if one can afford a $40000.00 car back in the early 80s can afford maintenance but just a thought they could have run those fuel lines closer to the side away from the cam cover since Porsche makes car to last?

 

On a fire related note, I had my power steering high pressure hose connection partially fail as I was on my in-lap on Monday. Sprayed fluid on the hot exhaust and it was just a little fire. I'm not sure of the life on these but a new one arrived from Roger this morning.

It can't hurt to check the condition of this hose based on location.

Here's what I tell everyone:

$3000.00 car needs $30.00 fuel hoses.

If its better than a $3000.00 car, and you don't have it insured on a "stated value" insurance policy, you better put the best damn fuel lines you can find on it!

The insurance companies think all of the cars are now worth "low blue book". They think a 1991 GT has the same value as a 1991 S-4 (below $8,000), because they don't have anything different to go by.

If I had a GT, a GTS, or any other 928 that was better than the "average" car that the insurance company is going to use to figure out how much my car is worth....I wouldn't drive it, until I had the best fuel lines I could buy.

So people didn't have to use rubber fuel hose clamped onto barbed fittings designed for plastic line ( a really bad thing to do), I spent over $5,000 having all of those strange "deep" metric adaptors made for these cars. Now they can use high end teflon lined hose, with crimped on fittings, that is totally appropriate for the job.

And the replacement Gates Barricade Hose (probably the best of the generic rubber fuel hose that is available) installed on fittings with barbs and secured with hose clamps....is like storing a leaky 55 gallon barrel of gasoline next to your barbeque!

If you have this stuff on your 928, do yourself a favor, Call your insurance agent and ask about a stated value policy.

It's not if it is going to burn...it's when.

 

I think your hoses are the best, not sure of price, please advise. Its not about price really, but need a reference point.


For 84 cars, is it ok to use rubber hose, like original unlined, over l barbed fittings, also original?

Am using Weatherhead hoses, which seem reinforced well.

Do these cars need to be removed from the road until updated?

 

Porsche never put rubber hose on barbed fittings. It's common knowledge, throughout the entire automotive world, that this should never be done. All the hoses that have barbed fittings are actually plastic hose, that has a rubber protective layer, on the outside. The barbs will cut the rubber hose, when the hose is clamped down, if rubber hose is installed.

All the fuel hoses that are rubber go onto smooth fittings, which have a "flare" at the very end to keep the hose and clamp from sliding off. The short hoses, from the regulators to the fuel return line, are made for rubber hose and clamps. That works fine and high quality rubber hose will last, in this position, for many years. The short hoses from the fuel rails to the injectors are also made for rubber hose. If you use the proper German sized hose, you don't even need clamps (like the factory did it.)

The fuel feed and return lines, on the right side, are plastic hose, on barbed fittings, with a rubber "protective sleeve" over the top. If you look closely at the "collars" at the end of the hose, you will notice that they are not crimped, but simply "slid" over the rubber protective covering, to keep it neat looking. This is a really easy way to identify plastic hose on barbed fittings, three feet away.

If someone has "cut" the original hose off and installed rubber hose, with clamps, on these two lines, you are, literally, begging for a fire.

I, personally, will not operate a vehicle, that I care about, that has rubber hose with clamps over barbed fittings. If the car was a POS, and I had a high stated value insurance policy, I still wouldn't operate it that way. Burns hurt too much!

Hell, the people that make the hose tell you that you shouldn't put rubber hose onto barbed fittings made for plastic line! They want to sell as much hose as they possbily can. Telling people that they should not put their hose onto barbed fittings made for plastic line sincerely limits their sales. If there was any possilbe way that this would/could work, they would not tell everyone that they shouldn't do this!

There's a large proportion of the 928 "world", all by themselves, that think that this is a proper thing to do. This used to upset me. Now I just smile and say: "For these cars to become really, really valuable, there are way too many of them. Fire is a great way to get rid of a whole bunch of cars."

 

Greg, I thought the 84 cars used rubber hose throughout the engine bay? Am I wrong? Can't seem to find pictures of those jobs unfortunately.

 

No. Plastic with rubber covering on the feed and return hoses, over on the right side. Even the '78/'79 cars had those two lines made this way (although they are slightly different, in length and ends.)

Porsche knew that rubber simply would not work, over on that side, with all the heat and movement.

BTW, the pair of hoses are $275.00. Teflon lined with braided Polyester outer covering, flame guard, crimped ends, with required adaptors. Lifetime guarantee. I don't care who owns it, how long it has been, what kind of fuel has been run through it....if it leaks from materials or age (no abuse, of course), I'll replace it.
