I have spares of a lot of D-jet stuff, some of which are known good
and available to loan to trustworthy types.

If the leak around the wire connection is just a seep, in operation it might
close up as the rubber seal swells in the gasoline. I had one that dripped
for a few days and finally quit.

You can send your injectors to Cruzin Performance and for about $12 each
they will clean and calibrate them for you and furnish new seals. They do
good work.

I may have an extra pump I could send you but I will have to check and
will not be able to do that for a few days. If it is only the pump head
and the rust is superficial you may be able to clean it and put it back
together. You need a 1/16" x 1 5/16" O-ring for each side of the plate.
If the motor turns freely you may have something you can use.
