Uro vs Wehrle Fuel Pump Relay?
I recently had an issue with my '82 911SC that turned out to be a faulty (red) fuel pump relay. I temporarily substituted one of the brown multi-purpose relays from the power windows and the car runs perfectly again.
I ordered a Uro fuel pump relay and when I first inserted the new relay into the correct socket, the car would not start! I put the multi-purpose relay back in and it worked perfectly. The Uro relay seemed "loose" in the socket and did not completely and firmly seat the way the multipurpose seemed to. I widened the pins on the Uro relay by pushing a razor knife down the slots in the pins and now it works fine except it still doesn't look quite completely seated against the socket - if you push it in, it seems to spring back just a tiny bit. In researching this, seems there's a lot of negative comments about the Uro relays. I found an alternative "Wehrle" relay at about twice the price. Wehrle says it is an OEM supplier to Porsche. Anyone with any experience with the Wehrle relay? Does it fit better or require tweaking the pins, etc., too? Thanks, John |

I only use the wehrle ones. Bad luck with UROs too many times.

I won't use URO on anything electrical or mechanical. Appearance items like lenses and such may be OK, but I've also had bad luck with more critical parts from them.

I read the bad reviews so bought 6 at once. Only 2 fit properly and I returned the rest. And then those 2 only lasted about 6 months each.
Was sick about the price difference and that the new ones aren't german. I found and bought a bunch of used Wehrle ones. They tested and fit fine. Funny world where 30 year old electronics are better than the new stuff, so much for progress. |

URO (ur on your own) is not really a quality (Chinese) maker of electrical components.
I'd buy some rubber trim from them but that's about all.

URO sucks outside of their tail light lenses.

The URO turn signal flasher I recently installed is not very high quality. I'd go for Wherle or Bosch when available.

I do not see the Wherle listed with our host.
Am I missing something?? If not, where have you guys found yours?

FCP Euro (*******.com) has Wehrle fuel pump relays ... never heard of FCP Euro before, but they seem to have good reviews. Curiously, their multipurpose relays are Uro's! :>(

What other cars would you find relays like this in a junkyard?

Well, the "Wehrle" fuel pump relay from FCP Euro arrived today. Funny, it looked exactly like the one that was in the car when I bought it and prominently has "MADE IN CHINA" embossed on the top! (I once read a Pelican Parts reply that "all the relays are made in China now.") FWIW, the packing list specified it was an "OEM" part. To its credit, it did pop right into the socket and the car started and ran properly without having to tweak the pins wider like I had to do with the URO relay. It is also distinctly different from the URO relay as far as the color (different shade of red) and embossing, etc. Guess we'll see how long it works!

Yes, in that it is a crap shoot....maybe you've just been lucky. I had one go bad in 24 hours.
I look for used Wehrle units on ebay etc. and have 5 of them for back up. The used one I put in place is fine 2 years later.
