Mostly true, but the pumphead o-rings really were round in cross-section, they've just been compressed for so long they became square. I think I may have a local source for metric o-rings, I'm going to see if I can come up with a replacement. All my defective pumps have leaked at the joint with the body, this is crimped and would be very hard to take apart and get back together. I think it's because they use MTBE in the gas in winter here, tends to eat older-type seals. All the leakers were off wrecks, a rebuilt has stood up for 2 years to it(knock on wood).
