Put in a nos bosch 3 port pump in my car after changing all the fuel lines. There is gas in both the feed and return line from the firewall to the pump.. no kinked lines there. I checked and checked my fuel line configuration. All seems good..
fat line from fire wall to step hose to filter to S / top of the pump. D line to feed into engine bay. R has the 2 return lines and the bottom of the pump. Now the pump has the correct bosch numbers on it, but does not have the S D R on it. I would think it's the same as my old pump even though it's not marked like that. fuel routing in the engine bay is fine. been over that several times. the pump turns on fine when I turn the key 1/2 way. I tried that like 30 times to try to get pressure to build up. nadda.. even tried pulling feed line in the engine bay to see if that helped. Even ran it directly from the battery for like 10 seconds like the instructions said.
Any suggestions on how to get this pump to prime/push fuel?

yup the s and d are turned around. Reverse them and the pump should work if it does not LEAK!!! We were suckered in to buying some of these and although they look great and work with the two nipple attachments reversed, most of them leak because the top is not machined well enough to seal the o ring and instead of using an o ring at the electrical fitting, they glue it and the gluing leaks. Bad news and a lot of discontent out there for a well intended item. We have received new pumps with the s and d in the correct sequence and the top problem fixed and the pressure relief valve replaced with a correct one, but they still leak at the electrical fitting. We are waiting for more to test. When we get them we immediately test them on the bench and then dismantle them to see if the guts are good.
