Or is there a way to tell from looking at the outside if its a gear or vane type pump? Last edited by Lahti35; 08/13/18 03:21 PM. RIP Trololo Man 1935-2012

After about 1939 was vane pump was discontinued and the gear punp sold as a replace,emt. The gear pump is a version of the 1937-1939 pump modified to fit a 1929 with all the necssary parts for the installation including the oval screen. The 1929 pump was 7 5/16" tall (gear version) Last edited by Chev Nut; 08/13/18 05:28 PM. Gene Schneider
