red fuel pump relays

[dirk07]

More active in LWB 911. Not really bumper models.
I have several red fuel pump relays lying around here. Two have the part number 911 615 108 00 and three have the part number 911 615 108 01.

I'm hoping the CIS gurus here can help.

When was each one of the two relays used?

They're universal relays, no further functional distinction, same ampacity, pinout etc. Pretty much the same as the blackish ones. The only big difference is that the red ones have a flyback diode to protect attached electronics like the fuel pump relay on the CIS cars.

The index 00 & 01 has no meaning for customers, it's an internal index from Porsche indicating a different vendor or manufacturer. You can use the red ones anywhere in the car, the black ones only where they are allowed...

Thank for the explanation Schulisco!

Thanks for your input, Schulisco.

My question is more or less anorak: When was index 00 used and when superseded by 01.

75+ used 911 615 108 01: https://911-manuals.questionable.services/porsche-pet-911-mid-year.pdf

I don’t have a 73.5-74 PET but thus presume the -00 relay applied to those early CIS cars. The 74-77 PET doesn’t mention it.

74-77 PET denotes 75+

Hi Ivan, yes just changed 00 to 01, same company.

Hi Silverlock, your reference is the 2010 dated PET.pdf?

Yes, the one I linked. The PETs had corrections made to them over the years.

I have the PET catalog for 73 and it doesn't refer to this relay type number at all.
The standard round relay referred to is 911 615 109 01.

[Schulisco]

Again - the index doesn't matter technically at all! So you can use them anywhere in all 911's using them.
Currently Porsche lists the red relays with index 02 ...

Got too many red relays laying around and made use of them.

You just wanted the to match the paint.

Can someone with the not matching red burgundy 75-77 spare parts folder or microfiche chime in?
