Oil & Fuel JD 4200 fuel line question

I'm sure it was filter first.

Here are the fuel system components in there respective positions with connecting fuel lines.

Yup that's it. I'm thinking of just plumbing the line through the filter first which would make the line from the tank the low point. As long as I open that tank drain occasionally that should keep water from settling in the line. It should at least keep water from settling in the transfer pump. I may eventually move the filter assy down near the frame somewhere which is how it really should be set up.

You are not worried about trying to suck fuel through the filter with the fuel pump? I think I would be..

I thought about that, not sure how much suction the pump has. I don't let the fuel get that low. I may try it, if it doesn't work I'll relocate the filter assy.

From information I,be been under the impression the solenoid seals leak and get fuel into the case. This may make for more force to move the solenoid.
Heat gun and pumping the priming lever seem to work for me. I'm of a mind to try a small torch so things are portable. Another idea is to rework the extra good solenoid I now have to be mechanically operated.

The solenoid does not shut off fuel. It deactivates the injection pump plungers.
