Fuel Pressure Regulator

My fuel pressure regulator is internally leaking. I have found this company skandix.de which is selling reproduction parts of d jetronic fuel pressure regulators and I was wondering if this has been used by any others and to what effect?  www.skandix.de/en/spare-parts/engine/fue...e-regulator/1018592/

I have a 1973 Mercedes Benz 450 SEL US model. 

Thanks,
John
 

Hi John,

that seems to be a new product since end of last year. I see that for the first time.

New to me, too...
There are alternatives that are less expensive.
But this seems to be a perfect fit.

Did you read the description and what they say here: www.skandix.de/en/news/new-djetronic-fue...sure-regulator/2902/ : "The fuel pressure regulators are now available in our shop under the numbers 1071886 and 1061995 . As already mentioned, they can also be used in BMW, Mercedes, Opel and other vehicles with D-Jetronic."

I would trust the product... there is a warranty of 2 years in Germany.
But I have the advantage the company is less than 50km away from my home...
I don't know the conditions if the item is shipped to your country.

Regards
Norbert


 

Seems like a trustworthy product. I think I will buy one

Hi John,

please report how that product works.

I will. Dr-Djet thanks for the quick reply. Further question: I want to install an inline fuel pressure gauge and I was wondering if you had any recommendations as to where/which gauge I should buy and place in the system.

Thanks,
John

Hi John,

I do not recommend to do so. I once tried and had steam bubbles collecting in front of gauge. To avoid that you should mount gauge lower than fuel lines and then you cannot read.

An update to this post. I ordered the SKANDIX 1018592 fuel pressure regulator and it seems to be a 1 to 1 fit for the old fuel pressure regulator. I've attached a few photos of the packaging and the fuel pressure regulator itself in comparison to the original. Are there any best tips or practices that can help with installing a new FPR?

Thanks,
John

Thank you, John, for information and the photos.

Yes, there are things you have to take care about.

At first, don't load the fuel-pressure by switching ignition on before removing the old regulator. Best is, the engine has been standing for at least some hours. Otherwise, you will be surprised about the amount of fuel...
And then - the short hose between FPR and the pressure damper tends to clogg, because this hose is not bent from the factory and gets a crincle. Use a bent hose. They are temporarily unavailable from DB, but you could use a GATES MFL1108 and cut out what you need.

You have to adjust the fuel pressure,use a calibrated manometer.

Do you have any recommendations for where to plug the pressure tester in? I am assuming the cold start injector, but I'm not sure which side. Also, is there a diagram for the direction of fuel flow I could reference?

Hi John,

remove cold start valve hose and install pressure gauge there.

Hello John,
The fuel line is a ring line.
The outlet of the FPR is opposite the adjustment screw.
The other two <opposite> connectors are connected to the same chamber.
