Re: Sea King 7.5 Fuel pump

1981 Eska leg with a Tecumseh 640-21 powerhead. The fuel pump is probably a bladder located in the flange of the carb. You can get a carb kit from a lawnmower dealer. Sounds more to me like the carb needs cleaning anyhow. The bladder will be included in the kit.
A Chrysler 7.5 would be a water cooled twin. Clinton and Eska 7.5s are air cooled singles. If it's air cooled use chainsaw oil @ 32:1. If it's a Chrysler use outboard oil @ 50:1.
I got a PDF file of the manual from EBAY and it says the fuel pump is mounted to the side of the cylinder block, Although my cylinder block is not exactly like the one in the diagram.
On the left side there's a rectangular plate with new gasket material that matches the other side (except the numbers are upside down on the left) but the outline on the block on the left side shows that something circular should be mounted there. I think that upside down plate came from the right side of another sea king.
Ive checked out the carb and if the fuel pump is in there it's microscopic in size.
Fairwinds marina says it's not a chrysler motor so they cant help with parts.
I did get back to the guy who sold it to me, apparently he never used it but his father did and he says that he had it hooked up auxillary on his boat and he thinks he must have had an external fuel pump in the boat. Is this possible?
