525 fuel/sea pump
 

http://www.ebay.com/itm/MITYVAC-AUTO...b1d08e&vxp=mtr this worked great,, when you have to service the 4 oz,s of gear lube in the sea pump/fuel pump,,,used the hand pump with the comtainer in between,,,used a peice of small (hard plastic) vacuum tube that goes in the filler plug,i shaped it like a 90degree so as soon as it goes in it can also find the bottom and a couple of different size rubber fittings helped put it together:evilb:hope this helps some of my brothers out
