I just blew my fuel relay, and I've been trying to find a replacement, these damn little things are sooo expensive!

I did see that Ideolas garage has a 16 amp fuel relay without the rev limiter, what does that mean in terms of our cars? Can we run that relay without any affect on performance, component lifespan decrease etc?

I guess what I'm getting at is, what is the difference between the stock part and this relay w/o the rev limiter.

I also will be swapping out the fuel pump since its blown a second relay on me, has anyone used the one Ideolas garage offers? other suggestions?

Several customers have purchased and (presumably) successfully installed and run the Walbro 60x version pumps that I offer. The only difference between the 604 and 608 is the pre-packaged adapter kit that comes with it, for use on different model year ranges (earlier cars use the 608, 79-onward use the 604). The pump is rated at 211 liters per hour which is more than sufficient for a 931 (even one with mild tuning, say up to ~250BHP or so). If you intend to run higher than 250BHP, you might want to consider a step up into a 250LPH capacity.

As for the fuel pump relay, there is no issue at all running the non-rev-limiting version in terms of normal operation of the car. It will not damage anything on the car. The only thing it will do is eliminate the rev-limiting feature, which means you need to use your right foot for that feature instead

thanks for the reply Ideola, I was hoping to hear from you. I'll be placing my order shortly
