[MCL968]

My car sprang a leak yesterday, and dumped out 1/4 of a tank of overpriced fuel on a relatively short trip. It appears that one of the two lines at the rear of the engine is spraying fuel onto the inside of the hood.

 

I am assuming that this is a bad thing and not an OPEC designed cooling feature. I am looking for replacement suggestions. Do I go with stock (if they are available) or Lindsey Racing braided lines, which appear more durable and are cheaper. Are there other options?

 

Thanks for your ideas and opinions. I guess they are overdue for replacement since it is a 1992 and I can't find anything in the records to indicate that they have been changed.

I don't think it really matters what you use as long as they do the job they have to do.

If original is still available you also have to look for the production date in order not to buy a new fuel-line manufactured in 1992 too.

 

Do you want to keep it 100% original if that is already possible?

 

For myself, if the price diference is too much and the original appears to be little dated too i would go for aftermarket products..

As above,

 

Lindsey, just make sure they are for the 968, as 944 are different

 

mine is 92, and my engine rubber pipes are original the rest have been replaced, think it depends on how much ethanol they have had to suffer

Well, I received the Lindsey Racing lines, and they seem to be very high quality. I opted for the thermal covering to make the lines less noticeable, and I think that was a good choice. I do wish, however, that they were not so freaking cheap with the thermal covering, Another couple of millimeters would not have killed them and it would have made the finished product look a lot nicer.

 

Now, the challenge seems to be removing the old lines. The top fittings were no problem, but the lower ones are so tight that I can't get them to budge!

 

Anyone out there have this same problem? I am not crazy about putting heat on the fittings to get them to break loose. Penetrating oil thus far has been ineffective.

 

Suggestions?

Follow up: The lines are replaced. If you have to do this job, put a steel block on one side of the fitting that attaches to the steel line from the tank and tap the other side of the fitting with a small hammer. Work your way around the fitting and the shock will help to loosen the oxidation in the threads and allow the fitting to break loose.

 

I am not a fan of the Lindsey Racing lines. They are high quality and nicely made, but with the adapters necessary to connect the line to the car, they are too long. Why they don't take this into consideration when they make the lines is a mystery, but in retrospect I would have just paid the difference and gone with the stock lines.

Thanks for the heads up MCL, my lines are starting to look shabby, good to know that stock is a good option. I

I noticed a little puddle under my fuel pump this AM. After initially panicking, I  remember that I probably over filled my tank yesterday, filled the charcoal filter then the pressure pushing it out overnight when the temps cooled down. (That was the
<span>rationalization<span> theory, anyway) Drove out to the meet-up for a big VW/Porsche fall color/canyon cruise and check it again, no drippy, so I wenton the drive, followed by a trip to SLC to pick up some M-B parts. </span></span>

<p style="font-size:12px;font-family:'Times New Roman';"> 

<p style="font-size:12px;font-family:'Times New Roman';">When I came out of the M-B dealership there were maybe 5-6 drops on the ground. Next time I stopped, no drops.


<p style="font-size:12px;font-family:'Times New Roman';"> 

<p style="font-size:12px;font-family:'Times New Roman';">Bottom line. I’ve been putting off my fuel system way to long so it’s time to replace that stuff. 


<p style="font-size:12px;font-family:'Times New Roman';"> 

<p style="font-size:12px;font-family:'Times New Roman';">Does anyone have a preferred vendor for that stuff. Rock Auto has a new Bosch pump for $105, so I think I’ll use that if I can’t find it cheaper elsewhere, but they don’t have any of the hoses, sealing rings, or filter. Also, doesn’t someone make a set of upgraded engine compartment lines? I seem to remember discussion about it.

So here’s what I found. As I’ve noted elsewhere, Gaudin Porsche seems to be the cheapest option around. Other than the fuel pump, which FCP has for $116 and Rock Auto has for $106. (Just like I found when I replaced my shocks and struts)

The only thing they didn’t have was #(12) but AutoAtlanta did.

I’m rethinking my earlier comment on the Lindsay Racing lines. I think for $130 vs $338 for the OEM lines, I can stand a little extra length.

ps: I can’t wait to see what sort of spooge is residing in my 32 year old fuel filter.

Update: the leak got a little worse after my Fall Color Tour cruise on Saturday so I tore into it yesterday. All the lines are perfect, as in “these hoses can’t be 32 years old” perfect. There’s also a “11/18/12. DP” written in the fuel filter, so I guess my buddy who temporarily “bought” my car had them replaced. 

   

Anyway, it’s the fuel pump itself that is leaking. Right from the crimped seam between the canister and the top. I’ll find out Saturday if they used an OEM pump or a cheapie.

If you cut the cover off the flexi lines under the bonnet, they are made out of a substance that is 100% ether proof
