Fuel accumulator
Swapped out an AFC injected engine for CIS injected engine and I need a fuel accumulator. Any thoughts on where I can find one for this 1983, 4.7 liter m28/11?

Thanks Nordicsaab. I did pick up an accumulator with that part number even though it said it was for a 1979 4.5 liter because you said it works perfectly on your m28/11, which is exactly what I have as we'll.

Well, these fuel accumulators can be confusing! An ebay search gave me the following results: part numbers 0438170026; 0004; 0039; 0025; 0009; 0017; 0031; 0024; 0061; 0030; 0019; 0034; 0029; 0035; 0022
Which ones would be ok for the /01 engine 4.5L?

0438170026 & 0022 is good on all CIS cars 78 through 83.
I am certain they will also work in place of the 928 110 197 04 on the early 77/78 cars. Seems to be mostly about the connections. For our cars there should be 2 x 14mm Female on one end and 1 x 14mm Male on the other.
I know 0024 does not work as it has 2 x 14mm Male on the one end.
This is based on actually supplying the 0026 to many customers but I am willing to learn if someone knows differently.

Be aware that if your car was NOT made to have an accumulator in the fuel delivery line it may not have the relevant connectors (and breaks) in the pipework to fit an accumulator. Its unclear to me from PET if accumulators were fitted to L or LH systems. Have you checked for an accumulator in front of the right rear wheel (under splash shield)? If there is one there, get the Bosch number or the Porsche number off it to locate the correct replacement. I think capacity would be about a demi-tasse - only the volume above the diaphragm has fuel in it.

That might mean considerable messing with fuel pipes in the right rear wheel arch to fit an accumulator in there ? Getting the pipework from the filter to the accumulator might not be too hard as they are short pipes (from the donor car?), but there forward its quite a job to fit new pipes - I have been there myself. Without a hoist, I found it not doable without cutting and joining the delivery line near the firewall - I couldnt lace the complete pipe into place.

Mine is a very early car....and had the accumulator right side up, but my pipes were very rusty and we're not reusable. The used one I got from Brian is inverted, with shorter pipes...they are the same part. I had to cut my fuel hard line, silver braze a ring on it, force my fuel hose over the ring, then clamp it...(all to ensure it does not blow off). Then used the shorter connection pipe. I did not enjoy the re piping. The bottom of the accumulator, (which is now the top on mine...) is supposed to be a vent line....but mine is too short to screw onto the inverted accumulator, so I just taped the vent off....my used accumulator is now leaking at that vent....quite badly actually.
I was wondering...why wouldn't one from a 911 work? Just a question, but I found a NOS that looks just like the one I took out....often wondered if the earliest cars used some parts out of the 911 bin...

Ron the 911 one will work its probably even the same part number. If yours is leaking out the vent hole its toast, if you hook that up to the vent tube its comes out the carbon canister inside the RF fender, been there, done that, cleaned up the mess....
