87 Turbo Return fuel hose

[Raulg]

Would anyone know if the return fuel hose #951-356-061-02 connects at the top of the fuel sending unit?
I was checking the wiring connections at the fuel sending unit, due to the gauge reading empty all the time. I may have to get a new sending unit.
The larger of the two hoses at the sending unit is dry rotted and I am trying to confirm which hose it may be.
It appears to be the return hose. BTW PP lists this part as N/A.
Any suggestions as to where to get a replacement?
Thank you
R.G.

Perhaps I can help. I custom make Porsche Fuel & Oil Hoses.

Email me with details of this hose. Photos would help.

Go to my user name and pick send email.

Also would help if you add your email address to your info.

Yes, that part goes from the return line up to the fuel sender unit.

It took me forever to figure that one out, and only after I took apart my whole system and looked at the lines. PET is useless for this one.

That end is just a raw cut end of the hose, and a hose clamp is used to attach it to the fuel sender nib.

Mine was rotted like yours is, but I would check with your local dealer for the part as I would bet that they can source one. That or get a custom one done up - it's a low pressure line anyway.

Good luck, Keith

If this is NLA from Pelican and/or Porsche I can probably make one for you. I just need the hose OD and length and description of the fitting.

If this is attached to the chassis hardline it probably requires a Female Euro Flare fitting similar to this.........

Thank you all for the replies. I appreciate your time.

BoxsterGT.
The hose looks similar to the picture you posted.
I will try to remove the hose so that I can get you detailed information.
It may take me a few days.
Thank you for offering to help.

Got some help from a local Pelican, as he needs this same return hose for his 87 944 normal.

He brought the old hose for me to duplicate. His hose is 9.5mm but uses a M14 Female Euro Flare fitting at the return Hardline on the chassis.



That's an unusual combination, as M14 fittings normally are mated to 7.5mm Hose. Easy to make up a M14 x 7.5 hose assy as my photo posted earlier. Those are standard Metric fittings. However it looks like I must adapt the standard hose up to larger 9.5 hose to connect to the fitting at the top of the tank.

I cannot locate this unique fitting anywhere as a separate part. If we cannot get new replacements from Porsche they will have to be re-hosed from the original or custom made.

Raul - Perhaps you can confirm these sizes for your application. I also found a photo online for the earlier model return hose, 477 209 071 C. It looks identical to the one taken from the 87 model I have here. I cannot tell what sizes are used however. Someone will chime in with that info I hope.

BoxsterGT & Keith,

I called the dealership and they confirmed the hose is NLA.
They suggested I call a couple of local shops. One of the shops recommended a hose/fitting fabricator.
The guy at the hydraulic hose shop, took the old crimp out, cleaned the old fitting and attached a 3/8" ID hose to it. I was very impressed it took him probably 5 minutes to assemble the hose and fitting.

I don't know the fitting thread / size designation. The outside hex is 17mm. The 3/8" ID hose seems to fit nearly perfect on the fuel sending unit connection stub and on the fitting.
The overall length was 26 inches. The new one is a few inches longer just in case.

I had a difficult time taking the old one out. Kept pulling from under the car. It appears there was some old tape keeping the hose in place in the spot between the top of the fuel tank and the trunk floor.
I ran a section of cord to fish the new hose back through the small opening. I expect a difficult time again. May grease the outside of the hose to help things.

Thank you for your help and advice.


New hose with old fitting on the left.

The new hose is a few inches longer just in case.

The old hose is almost 26 inches long.

The old fitting was re-used. Photo shows fitting on old hose.

[BoxsterGT]

That looks good Raul.

Here's what I came up with. It's the old crusty M14 fitting as in post #6 above; sandblasted, painted & crimped to a new 9.5mm E-85 resistant hose............




So it looks like the only practical option is to re-hose using the old fitting.

Len,
You are right, re-hosing the fitting appears to be the only option.
It would be nice to find out where to get the fittings (used) for future and to help others.
I installed the new hose today. It was pretty tough to pull through the small opening between the top of the tank and the underside of the trunk.
Onto the rear brakes now.
Thanks for your advice.

Boxter, tried to send a pm but says your box is full.

[BoxsterGT]

The best way is to email me. Just go to my user name and pick "send email".

Just did one of these today for a 968. Customer was waiting and I forgot to take a photo of the finished product, but here's the original.........



The hose is 610mm (24in) long, so the cost of re-hosing the original would be $26.50 plus Priority Mail postage.

Raulg-

It probably doesn't matter as this is low pressure, but the crimp sleeves on your repaired hose are wrong. Most local hydraulic shops have sleeves that are much too long and their SAE crimp dies are not suitable for our DIN hose fittings. What happens is the following.........



The crimp crushes the hose at the bump on the fitting meant to retain the hose (see photo in my Post #6). Over a short time it results in this failure..........



Again, with the low pressure of the return side it probably doesn't matter. On the high pressure feed side its another story.

Len

[Raulg]

Len,
I agree. On a low pressure hose most likely the length of the crimp will not matter.
The return hose is in a location such that the crimped connection is not near any bends.
I didn't realize there are SAE and metric? dies.
Thank you

Boxter if that was directed towards me, not what I need. I need the fuel pressure damper hose for an 87 951.

Hello BoxsterGT,

Can you make one of these hoses for my 89 944 NA ???

madeyman- As above, please email me and send your old hose or at least your old fitting.

I cannot buy this unique fitting w M14 threads to a 9.5mm hose to make a new assembly, but I can "Re-Hose" yours.

Len

[BoxsterGT]

Bumping this to the top, as this return hose fits most of the 944 type models.

My email is len.cummings at verizon.net if anyone wants to ask about this.

I do not reply to pm's as we cannot send photos via pm.

Email ONLY please.

Thought this might help as my new replacement is much easier to install than the 10mm Hose of the original.

Original (Left) has a M14 Female Flare fitting at the Chassis and uses DN8 10mm Hose up to the Tank Return. This is a DIN mismatch requiring a custom M14 Female Flare Fitting down along the Chassis connection.





My replacement uses a M14 Female Flare with DIN standard 8mm Hose at the Chassis connection with an adapter at the Tank (Right) to the Porsche 10mm Hose fitting.



This has the added benefit of a smaller 8mm hose being routed between the Tank and Chassis, when the original 10mm hose goes in with great difficulty.

For info, please email me ONLY. No pm's as we cannot send photos via pm.
