Getting ready to install a K27 turbo tomorrow, and have read about removing the fuel pump relays and cranking the engine to prelube the turbo with oil.

Now, where are the relays?

I've done a bunch of searches, and from what I gather, they are at the front of the car and they are red in color. Any other tips to make sure I pull the right two?

Thanks much

They are in the fuse box in the front trunk. They're round and they may be red or black.

On my '87 the fuel pump relays are the first two relays closest to the windshield...they are both red on mine.

Thanks for the info!

Agreed. On the driver's side fender fuse panel, you will see the fuse panel with the seven red (round) relays on top of the fuses. The the two nearest the windshiled are the fuel relays. You better keep a couple of extras handy incase you blow one.
I have blown a fuel relay and could not restart the car and did not have one. Remember, you can pull the relay for the fogs or the horn and get home or to a Napa parts store. Did you know that NAPA is the only parts store to carry the original German made relays? Everyong else carries the Chinese made relays. AND they are the same price.

I didn't even think to try NAPA! I would have just ordered 'em from Pelican! Thanks for the info!

I ordered a set of four from Pelican, THEY SELL CHINA parts for the relays. I was a little taken back about this.

What other car uses these round relays? I never thought that NAPA would carry them...

I've noticed that there are red as well as black round relays in the fuse box up front. Is there a difference in specs between the red and the black? Perhaps the red handles higher amperage? I was going to buy some spares to carry, but need to know if I need both colors or if one color suffices for all applications. Logic would seem to dictate that different colors mean different specs.

Also...I just saw a replacement set of the small porcelain fuses for the 930 on eBay.(see item 200011190233)... I have no idea where they're made...but is it particularly critical to buy an "OEM" porcelain fuse?

It is my understanding the black relay is the older style and do not handle as much heat and tend to melt (seize) sooner that the newer red relay.

How sure are you about this? I'm a bit skeptical about your claim, as red and black (round) relays appear side-by-side in 911s. Pelican lists the red relays as "fuel pump relays" and the black ones as "fog lamps, horn, etc."

I also am still a bit skeptical about the color of the relays because it would seem logical that a red one would signify a relay that perhaps was designed to carry a heavier load? In my car, (87)I have red and black relays, but the fuel pump relays are red. I also see that the various parts houses continue to carry both red and black relays...so if the red ones were meant as an upgrade and a replacement, then we shouldn't be seeing black ones in current parts inventories. I guess to be safe, I'll just buy a red and black one as spares and replace with the same colors.

They have different part numbers for a reason....

I stand corrected. It's just Ievery 930 I looked at all had red relays. Do I need to replace some with black ones??
I'm lost here.
