Which DME Relay?

I need a DME relay....Porsche wants $100. Is it worth it?

This is the square oblong relay under the seat in a 3.2 G-model Porsche 911....1984

If not, our host has 3 different suppliers around $40 bucks....suggestions, comments?

Thanks,

Scott

I bought the Solid State Relay with the extra few seconds of fuel pump run time. I have a German spare, that I suspect I will never need.

The SSR is made by a US company. They are made and sold by from Focus 9 Technology. After 3 years and several road trips mine has been flawless.

Definitely would not but the dealer relay for $100
I would buy the Focus 9 technology solid state with pump prime, should be about the same cost or less with the shipping and much more reliable and the pump prime feature is nice.

personally i have always used the stock relay and did many many miles(on the bottom signature) i had never a problem with it.
Suggestion :get yourself an old stock relay not new one...the old stocks are made In West Germany...later version was made in Hungary..same good quality.

Ivan

I have plenty of them if you like i send you one for 20 bucks and you pay for shipping.

Focus 9. Solid State. Looking at the specs.
Is there a real argument against going this way?
I dont see alternatives that are better.

I would grab the solid state one and then modify the one you have to always power the pump. I keep that one as a backup should I need it.

Focus 9 solid state.

All day. Everyday.

I have one installed in each of my 3.2s. The three second pump prime feature is NICE. You get audible confirmation that the fuel pump is operational everytime you turn the key. Superior functionality + 99.999% reliability (or, as close to that as possible) = No Brainer.

I don't even carry a spare any longer. Livin' life on the edge, yo!

Love these cars, but if there's a plug & play solution that improves reliability to 21st century standards... I'm availing myself of it.

Focus 9 Technology

Morning Guys,

Thanks for all the input, I've ordered a Focus 9 Tech solid state DME relay for the car.

$95 delivered BTW.

I received an email from Joe Baumbach, Founder/Engineer of Focus 9. He indicates that he has a prototype DME box in development for our cars. There was some confusion on my part as to which relay I should order so I sent a message to the web site contact email. He answered on Sunday.....impressive. Bodes well for customer support.

I didn't know this option existed before this post guys, thank you.

Scott

Honest question: is there any issue for the gas pump with the forced priming relays?

When the prime/pump one I bought had a minor problem Joe overnighted a new one to me without charge no questions asked, and provided me with postage to ship back the one I had. I'll support a guy like Joe any day of the week.

No.

That is the reason the fuel return line is the same size as the as the supply line. The excess gas just goes back to the thank.

I guess if you add up the extra few second of run time the pump operates after a 10,000 starts you have 8.3 hours. That would be nearly 3 years if you started your car 10 times per day every single day of the year.

Considering most of the pumps run 30+ years with no issues, don't worry about it.

Hi everyone, as of August 2019, URO released an updated version of our DME relay 911 618 154 00 for the 1984-1989 3.2L, Pelican should have it in stock now or very soon. Our prior version of the relay wasn't the most reliable, so we redesigned the internal mechanism to be a more accurate reproduction of OEM.



Here's a photo of the first generation relay. Many online retailers will probably show the 1st gen photo in their catalog for quite awhile, even if they have the 2nd gen on the shelf. Our warehouse has been shipping the new version as of early August 2019.




If anyone purchased our 1st-gen relay 911 618 154 00 and had any issues with it, please PM or email your purchase details (date, retailer, order number, shipping info) to "sales at uro parts dot com" and we'll be happy to send you the new second-gen version as a warranty replacement.
