Top quality work! Did your car also have the shock absorbers in the side of the gearbox with the special brackets mounted? My car had this but wad removed at some time in its life. I had to fabricate my own brackets.
Ad0911 Thanks for your kind words. Regarding the transaxle shock absorbers.....funny you mention that. watch this space!
I would love to see an image of what you have fabricated. The early photos of the part (powertrain images) differ in design that what is shown in the PET drawing. I am curious to know which you chose to fabricate? (one of them is substantially more difficult that the other)

I will make a picture of the brackets I made. It was mostly guesswork about the shape and measuring to make it fit. Don't expect any laser cutting quality. I made these from a rectangle shape tube and manual tools. I had them plated when they were done so they appear correct from a little distance.
...I would be happy to provide full details and pricing to this 928 community.
Great stuff! So happy to find someone digging-in to the nuances of early 928 fuel delivery.
Certainly, I would like to know more, though no need for pricing.
Did PartsKlassic supply all the fittings and tubing?
Did any original pieces need to be reused?
Just for reference, this is 1 of 3 fuel delivery setups for 1978-79. This is the 2nd version, most common to mid-to-late '78 US 928s. 3rd version is most common to '79.
First had an 'right-side-up' fuel accumulator, w/a 'wrap around' hardline tube from accum to fuel filter. Hardline from fuel filter to engine firewall fuel hose (no intermediate fuel hose, lower right-rear wheel well). Fuel vapor hose thru check valve, thru expansion tank, thru hardline tube, to atmosphere.
Second (as depicted here) had an inverted fuel accumulator. Accum feed hose w/an integrated 'wrap around' hardline tube. Adapter fitting from accum to fuel filter. Fuel vapor hose thru check valve, thru expansion tank, thru hardline tube, to charcoal canister (front-right wheel well).
Third same as second, but w/o accum vapor line. Single-vent expansion tank, thru hardline, to charcoal canister.

Well, here is my piece of homework based on the drawing in the PET. Do you have pictures of the orginal brackets?
Hello AD0911,
Thank you for the prompt and comprehensive reply. Wow nice bends. What you have fabricated is very close to the PET image. Below is the style I noticed in three pictures in the early 928 Service Information Manual. I am now fabricating one set of these. It is really slow and painful. As soon as I have a good progress point during fabrication I will post some images.
I think being these bracket are likely to have a very interesting story with the powertrain engineers at Porsche -circa 1975-76, when these prototype images were first available. Maybe some has the factual history on why these were deleted? It is easy to speculate, but I would love to hear a quote from someone involved in the development.

I think the parts in your picture are more likely to have made it into production because they are easier to produce in volume (but a lot harder to make by hand).
About deleting the part: I think it was deemed unnecessary. The shocks at the engine did the job.
I should have asked Peter Falk who was responsible for testing the car at the time. I met him in 2014 in Leipzig during a Euro 928 meeting. He signed my "project 928" book on the pages with his picture and a 928 cam cover I brought along.
Looking again at your pictures I realise that the shocks I have will not fit these brackets because my shocks require a through bolt.
I did not put these on the car for the same reason I think the factory deleted them. But I should ,make a picture of them while on the car. Seems appropriate. And nice one for the book. No one will ever dive under the car to see them I guess.
First item: you are very fortunate to be so close to the source wherein your Euro events attract the original designers. Well done on getting Mr. Falk to autograph your Project 928 book. I think you should install these after all your effort to fabricate. I agree it probably makes no difference, but are you not curious to drive your car 'back to back' without them / then with -to see if you notice anything different? I am planning on installing my from the get go. Your posting on this thread is inspiring me to get back on the task and complete these! Thank you!
Wow! Nice work on those fuel lines. Some of the early stuff is so different & special, I wouldn't expect the 'usual suspects' to have them. Not a rip on them, just that the demand is not there.
I've rebuilt hoses and tubes with original fittings as cores. That's easy.
What would get me drooling is if someone has a source for the really oddball fittings. I looked over the Partsklassic website and I can't find them (only the more typical metric fittings are listed).
Partsklassic had only a few of the required fittings. He normally stocks 911 and 930 turbo fittings that are apparently too small in ID. What is required is sending him your original hoses, he breaks them down and then media blasts the fittings before reassembly with new ferrels and hose sections.
New 928 T-Shirts available -poking lite fun at the 911 crowd
Ok. Now available. New T-Shirts that put the first 928 into proper perspective with the original 911 design. These are all Haines Beefy T's. The usual sizes -including big boys. Available now at 928 International.
