Testing fuel pump link lead
Other than the basic continuity check, is there anything else that should be tested on a fuel pump link lead noise filter?
The pump side connector on my primary pump link lead has melted. Fortunately the replacement pump came with an adapter harness. I am thinking of salvaging the noise filter by soldering it to the adapter harness.

So, to revive and expand on this question (old post, I know), is a simple continuity test and a visual confirmation that nothing is burned all that is necessary?
If I elect to re-use the link leads I want to be sure they are tested properly. I Don't want to find out after the tank is put back in!

I actually went the route of taking the pump and link lead connected and gave it 12V to see what it did. The bad one did nothing, the good one had the pump running. So then I tried the pumping pump with the other lead and it didn't work, isolating the link lead as the culprit.
Be careful using electricity near fuel; I wired everything up to my power source before giving the juice. Spark risk near fuel vapors is a bad time waiting to happen.

I am researching now so I can begin this project in the morning. If I can determine by 1pm whether or not I need either of the link leads, then the local Jaguar dealer can have them for me the next day. If not, then the car will be out of commission probably until my days off NEXT week, in which case the E30 would get some exercise.

Just for closure on my issue, because I like that when I read old threads, I ended up testing the old pumps and link leads with a 9 volt battery and speaker wire. I tested both leads and both pumps. Both leads worked fine and only one pump would work. I also did a continuity test on the leads just for assurance.
I re-installed the link leads with the new pumps and the car drives great.
