Jerry has some stainless replacements, or you may have a machine Supply outlet nearby where you can also get them.

I put some RTV on the threads to keep water out and to keep them from seizing again. (Common problem after some years.)

Ok ...the engine has been refreshed and buttoned up....Gas tank was completely cleaned out...Went and put in 20$(12L) of gas and nothing comes out of the lines when I jumper the pump..... The connector is flaky as I get an intermittent reading of 6-13a.....

Would a clogged fuel filter cause this???....after old fuel and water ran through.

Well, it would take solids of various sorts to plug the filter. If there was some debris in the bottom of the tank, certainly either the pick-up flilter(s)(attached to each pump) or the inline filter (on the frame rear of the RF wheel well) could become blocked.

As for the different current readings, assuming proper connections, the normal draw is 8-10A, divided between both primary and secondary pumps when both are under load (pumping fuel). (IDK what the current might be if they are not immersed in fuel.)

ok I blew into the lines at the tank going to the fuel rails....and got a bunch of

crud and water out into my catch bottle ...the lines seem to be unblocked now.

But one problem....the fuel pump will not come on anymore after I try and jump

it. Is there a fusible link somewhere....near the battery area for the pumps???

FP1 fuse checks out fine...F&@k....I have a massive headache and working in

40+ degrees C is NOT FUN!!!!

I'm getting current to the fuel tank connector.
(blew FP1 fuse in the process.)

[Chris26]

the harness seems to check out.....pulled the pump assy and jumped them directly to the battery and nothing....I think the stress from the clog took them out!!!!
