Posted: Fri Aug 15, 2008 9:46 am Post subject: Fuel Accumulators???? |
|
|
Does anyone know if there are other cars that use the same fuel accumulator or compatible accumulators. I'm getting an NA 80 924 back together and am in the process of rebuilding the fuel lines. The accumulator looks shot, but replacements seem a bit steep, just wondering what my options are. _________________ 1988 Porsche 924S

three questions
One: did you unscrew the screw on the bottom a little and see if fuel came out? If it does then its stuffed
Two: Do you have 2 accumlators or one? (someone will probably know because of the year but I dont)
Three: how much is steep? _________________ 1977 924 2.0 Auto |

pretty much screwed if you need new accumulator(s) as far as replacements go, easy to spend several hundred on them and not many alternatives. However,rumor has it certain mercedes accumulators are of similar spec, though not direct, fittings are different. If you swap out the fuel lines id bet something could be cobbled together to work. _________________ Eric

This woul not supprise me, I have noticed a few other thingss on Mercedes at the self serve wrecking yard that look like they would fir the 924 with little or no mod so maybe this is worth a try. _________________ 1977 924 2.0 Auto |

What about a home-made accumulator? Could you just put a sealed piece of pipe in the fuel line like plumbers do for water supply lines? Seems to me this would do the same thing as an accumulator, but it's easily within the realm of cheap DIY'ers.
To use parts all rated for fuel system use, I could easily imagine a T-fitting, with the base of the T pointing upwards into the bottom of a fuel filter, with the top of the fuel filter capped. The air within the fuel filter would act as a spring to maintain fuel pressure with the pump off. If there's insufficient volume, a 2nd could be used. It's a great use for old fuel filters!
A filter body with the elements removed would be preferable of course. . . _________________ 78 924 NA

The accumulator has an internal rubber bladder that holds pressure in the system after shutdown (aids in hot starts) and smooths fuel flow. When the bladder ages and rips, it leaks fuel, hence when you loosen the screw on the bottom of a failed accumulator fuel drips out. Making one may be slightly outside the skills of the average home mechanic. _________________ 1987 951 - M193 Version for Japan |

It's definately shot, I took the screw out and fuel ran out for a good 30 seconds. Looks like I'll be getting a new one _________________ 1988 Porsche 924S

Those guys have excellent prices. Alternators and starters are cheap compared to what I usually see.
Another place I found that has reasonable prices is the PartsBin.com Got a complete exhaust system 183 bucks _________________ '78 924 NA with Collector plate

Fuel accumulators for cars up to 1978 are about $100 then for 1979 onwards the price jumps to around $250. No idea why the jump n price but the AutoHaus Az prices are still amongst the best. _________________ 1979 924 (Gone to a better place)

| The early 924s have two of 20cc accumulators while the later (79+) have only one 40cc unit. Still no justification for the vast price difference though. |
