Anyone having trouble with GMB pumps. I replaced one less than 20k old and now the one i fitted has failed in under 20k. Same problem again leaking. I now have to order a replacement when I get back home from camping. Not going GMB again. Gonna have to try a Gates i think.

Yeah I'm thinking they must have VSLover. I've had older GMBs still going strong after 5 years. Mech up the road reckons GMB are good. But i think they have gone to **** now, both failed pumps have been the seal. Gonna see if i can email the seller and see if he will send a free replacement. But still if it goes again then its annoying to fit another, in 12 months time.

I have done a fair few GMB pumps, only had one fail and it was on my own car with only about 5k. Leaked when sitting not running. I still rate them as a better brand and have the better impellers.

possibly but a Gates is under 50 bucks, gen would have to be 150 if they can be bought. Only way i am fitting another GMB is if the seller sends me a free replacement. I've used Duraflo and they lasted over five years and was still going when I scrapped the engine.
