1984 928 Fuel Pump
My fuel pump is going out on my 1984 928. The mechanic said he had eliminated everything electrically during testing.
I am being told that the fuel pump from a 911 would work and does not have to be from a 928. Any help or advice would be appreciated. Thanks, Karen One of the guys from the 911 parts site has a interchange manual on fuel pumps and says an 1980 - 1985 pump will work. This looks like what I need have a look at this pdf it is the Bosch application guide http://apps.bosch.com.au/products/saa/efi_crossref.pdf it lists the 928 as having a 0 580 254 053 the same as the front pump in the turbo and the stock pump in the 80-85 911. The 0 580 254 053 is listed in the bosch Motorsport Range and the specs are available here http://www.beekautoracing.nl/img/fuelpumps.pdf The only two viable alternatives are the cheaper 909 (only flows 148ltr/hr not 175ltr) and the 044 (requires a input fitting adapter. __________________ Steve Hall --------------------- 1988 930 Targa 1991 E36 BMW 318i 2004 Mercedes ML270 Thanks, Karen I was told that it is the flow rate, operating pressure and max capacity that is important when matching a Bosch fuel pump from an interchange chart. I was able to purchase a new pump out of California that matched my car for $160. This was the best deal available including several used pumps. Thanks for your help, Karen Last edited by JK McDonald; 09-03-2007 at 03:55 PM.. |

wrong....
you need 928.608.104.01 which is not swappable with a 911, the flow rates and check valve are different

you can go by the Bosch# and be ok, don't rely on someone just saying any 911 pump will work, it doesn't
I'm still not sure that will work for you anyways, the chart you list shows 80-83 K-jet, your 84 has L-jet

Chart is from Australia so maybe its for a ROW (80-83 K jet) instead of a US model car?
Andial Porsche shows a Bosch 0 580 464 017, Porsche 928 608 104 01 Aussie chart shows 0 580 254 053 as the universal replacement part. Use some caution where you buy it, this is one I have seen on ebay from China. I would pick my favorite supplier of genuine Porsche parts and buy the real deal. I also had better luck searching with the Porsche part number than the Bosch universal, ymmv.
