1986 3.2 Carrera engine....
I have two bosch fuel pumps here, they look identical... Bosch part # 0 580 464 021 or 0 580 463 010 they look the same other than the part number (IMG:style_emoticons/default/popcorn[1].gif) |

Jim Have you a picture? My late style pump has no check valve. It does maintain pressure until it bleeds back through the pump. (well it did until I put a 3.2 in there) Attached thumbnail(s)
