I pulled my old 924 in the garage the other day and decided to start working on it again as long as the motivates stays around I found a fuel distributor block rebuild kit online for about $50 (allot for a bunch of O rings isn't it ..lol)

While I am at it , I know the fuel accumulator used to leak down on this car if I did not start it every day and dripped when running , I found some new ones online the cheapest one being around $100 but I was just wondering if there is a chart to cross reference the fuel accumulators form the 924 with other brand cars to see if there is a cheaper one I can get at a local store ???

You can source the o rings for a fuel distributor much cheaper than $50.

You can make a DIY fuel accumulator as well, but $100 for one is pretty good deal. You can come across some used ones for $20-$20 sometimes, but you take your chances on if the seals in them are still good.

There are write ups on rebuilding the fuel dizzy and making your own accumulator on this site, you just have to search.

yep I figured the O rings could be had much cheaper , but not being sure buying the over priced kits takes the headache out of it .

I have searched for Fuel accumulator , DIY fuel accumulator even just searched for rebuilding the fuel dizzy and making your own accumulator I did see where in one post someone explained how to take the "fuel dizzy" (what I am calling the fuel disturber block) apart but I am past that point. maybe I missed it but I did not see anything about the making a fuel accumulator or swapping it with one form say a VW which is more along the lines of what I was think I could find locally

Fuel accumulator is a pretty simple device. essentially a diaphragm with a spring for pressurizing it. The 924's had two different setups for the accumulators.

Early set up consisted of two 20 cc accumulators.
Late set up consisted of 1 40 cc accumulator. (recommended)

This car is essentailly a VW so if you can find a 40 cc accumulator out of a VW, the threads should match up and it should work.

When the accumulator "goes bad" all that is really happening is that the diaphragm is no longer sealing. Since the unit is sealed, it isn't possible to replace it without cutting it open. So a DIY one could be made one of two ways:

1. cut open your current unit near the top. Remove the diaphragm. Source a new one (probably the most difficult part). Install it. Seal the unit. Sealing it could be tricky. Welding is out unless you have balls of steel. JB Weld is possible maybe? Whatever method you choose, it has to be relatively flush internally and it has to be able to withstand fuel and pressures of 80-90 PSI.

2. Same as first but, you construct your own canister. Canister could be made of plastic or what ever floats your boat. Have the lid sealed on with clamps or screws or clips. You would need an O-ring between the lid and the canister. Lid needs to have 2 nipples (In and Out). They don't have to be threaded like the original because you can use fuel line and fuel clamps instead. You have to make sure your fuel pump has a check valve on it, if not you will need to add one between the pump and the accumulator. Yours SHOULD have one if it's a stock unit.

OR

You can take the red neck engineering path and wire the CSV up to an interior switch. This will provide you with extra fuel on demand to help start the car during warm starts. I tried this method and it didn't work all that well for me so I ended up finding a used 40 cc accumulator for $20 on ebay.

Thanks, mine has a single accumulator but didn't realize they where different size so that 40cc info is very useful .

ya I tried to see if it would come apart before when thet didn't work I tried to seal the canister but it eventually leaked again ........... I haven't found any $20 ones on ebay yet but think I am just going to keep watch for a new or used one and go form there. I did see one VW one on ebay that looks the same except has a extra hose barb out the bottom that mine does not

I did match up the O rings for the fuel distributor block and rebuilt it today but still have to reinstall it and see how it does

oh the welding gas tanks or parts don't bother me , at least hasn't yet

I used to weld up the metal outboard fuel tanks and still occasionally weld up aluminum airboat fuel tanks, actual welded a plate in the bottom of my 944s tank so I didn't have to pull the whole thing out of the car but it's difineatly not something every body should try doing

When I needed new accumulators, I went to a junk yard and pulled a few out of the 3 924's they had there. If I were you, I'd call around to the pick-a-part junk yards in your area and see who has any 924s, and then go out and yank 'em off. Take 'em home, test 'em, and hopefully you'll have what you need. It'll cost about $20.

Instead of welding(heat bad)try "body glue"
Its used for glue welding body panels together sticks like *hit ina baby blanket impervious to just about everything and if you do it right no rust
3M has a good system.
Nice way to cold weld 'way better than JB in some (most) cases
Mrpete

Once you use it you'll dream of new ways to use it
It will come apart with tlc and a heat gun I think corvette uses it to put their cars together I know I have

Rattlinbone ,
there isn't allot of pick an pulls around here for that matter there isn't as many junk yards that will sell to the public as you would think either that is one thing I difinetaly miss about living up in GA

MRPETE,
I got no problems welding stuff up but that would probably be more trouble then it is worth do do a accumulator I figured if I can find other vehicles that use a similar size that I could make work and maybe find a little cheaper I would be happy with that, I am just looking for functionality not show quality type car

Im gonna bump an old because I guess its relevant. Im looking to make an order soon from GAP. I was looking on there, and for the 1977 Porsche 924, they list a single fuel accumulator. Bosch 477 209 083. I've got a 77, with 2 accumulators. Does anyone know if this is a 20cc accumlator or a 40cc? If they are 40cc, can I just use one, or for some reason do I neeeeed to use 2 20ccs?

[scm924s]

My 77 martini has 2x 20cc accumulators, they changed to one single 40cc when they fitted the in tank pump I think.
