We did not until yesterday. I will respond to your email

Was thinking the same thing. Lot's of development work to see nothing that much.

Did something similar many years ago by putting a small camera to watch the front flex plate clamp and drive shaft union when driving. Very boring video, even when slowed.

Hee hee

It would still be kind of cool, though. First there was the visible man, then the visible engine and now the visible fuel pressure damper.

Hi Kevin,

I completely get it.

Pot calling the kettle black as it were.

Good luck with the rest of it.

Cheers.

I don't know if this is the right thread or not, but has anyone done a correlation between vacuum leak down vs time to determine if a FPR is failing?

Speedtoys

They should have no leaks...so there is no "time" for them to return to atmospheric..

checkmate1996

so if I put a mityvac on an fpr and crank it up, it should hold constant until the vacuum is removed?

If someone builds something unique and or provides a service of top-notch quality to this small community, why re-invent it if it works and as Greg says this is a very small community and there is not a huge demand for these small items -- a modest to small demand but not huge. Is it all cost-driven, like is there a desire to make something cheaper than say GB's stuff? Is there are 'market' for this with dwindling numbers of cars on the roads and smaller numbers of cars going back on the road to make the cheapest item or provide the cheapest service? I can see if you stumbled into making these dampers if you made dampers professionally and a 928 literally fell into your lap and you discovered there was a need for dampers and no one was making them and if they were they were junk -- then a need is really there, right? Sort of like me having a 928 given to me, and I'm a professional media blaster, and I see a bunch of ugly parts and I just put them in to blast to make them clean and pretty and then read the absolute horror stories many ignorant people undertook to 'refresh' their Intake manifolds (the 30 hours of hand cleaning then chemicals, and then putting it in the dishwasher was a good one) using **** poor methods and equipment...all situations I told you all I can and do and have and will continue to 'solve' for you -- seeing this I saw a market for this and I actually looked -- looked really hard for anyone that can do and has what I have and bring to solve this -- if I found them I would have not jumped in both feet as I have. But, there is no one. It's a small market, these cars are dwindling in numbers, duplicating another's good product might bring prices down, but, is that the intent on a dwindling market? I tend to doubt that is a recipe for success.

That is a very short sighted approach to life. If everything worked as it should there would be no need for alternatives. But when parts or services, do not work to the requirements of customers who pay the bills, alternatives will always be needed.
Try buying products like fuel pressure dampers, regulators and fuel hoses and you will soon find that the market has very little in the way of available choices. The 928 market is not small by any means and the demand for product is very high - we struggle to keep up with demand. We cannot make product quick enough. I can't buy product from GB but have a mass of customers looking for alternatives which I am extremely happy to provide. I am very happy, that there are equally clever peeps out there, that are designing and building products for the 928 community. Like Kevin, PK, Bart, Dennis, Richard, Geza to name a few.
Do not EVER think that you are THE only one that can provide a product or service in the 928 World. I never will!! Competition will quickly bite you in the butt. Competition is everywhere no matter what product or service you provide.

Nope just a desire to be able to get it

Well, availability of product was never qualified in this thread, assumptions were that product was available. But, not too surprising these days with supply chains being screwed up everywhere. That is actually good news the 928 market is growing -- really good news, guess the popularity is finally gaining steam and the old 'Field Finds' are being scooped up, I know I scooped up 3 of them and a 944S.

I believe Greg is no longer selling his while he investigates some failures. Let's hope he can figure it out and get back to selling them soon. Competition is a good thing.

What makes my design better and different is the use of screw-in inserts to serve as fuel regulators, front and rear dampers. That's where rubber meets the road, so to speak.

This design allows me to use more than one source for the diaphragms. And if a vendor is out of them I can re-tool my inserts. No need to reinvent the entire housing. $$$'s

Basically, I can match a diaphragm vendor's diaphragm to an insert and offer them as a package as vendors come and go.

The same goes for the springs. Also, my caps feature a vacuum port perpendicular to the housing. Much like my fuel pressure regulators and dampers.

So, all this chatter about somebody copying somebody else's product is just that, chatter. I improved on the Bosch unit - it's that simple.

In the end it's the market that will decide. Yay capitalism.

Has anyone successfully swapped the EURO dual rear regs to make one a damper. I am having challenges with the rear regs as they have hose tail fittings.
