Question? DIY fuel pump hotwire kit I'm making my own fuel pump hotwire kit for my Walbro 255. I'm going to just run 10g wire from alternator to relay and trigger the relay with the original fuel pump power wire, but how do I get the wires from the pump out of the tank? I saw on the DIY twin pump sticky, they drilled a hole in sending unit and just used a grommet and some GOOP. Will that seal it good enough? I was trying to find some kind of wire bulkhead connector or something besides a grommet. Let me know if you have any ideas.

Drilling a hole in the sender & using glue/silicone is really a poor way to do this. You risk having leaks & also may end up using wire in the tank that is not rated for immersion in fuel. No sense in making your own to save $20-30 & end up with something dangerous or failure prone when there are good kits out there.

Not to discredit your sticky in any way, but as an engineer & business owner, I could not recommend doing something like this.
There are too many variables that could cause a bad outcome. All it takes is a bifferent brand of cement that dissolves from fuel or a brand of insulation that does not agree with fuel used, or the fact that there are numerous mixes of fuel out there that may interact differently with one of these components under a non-tested situation.
Trying to defend myself (& potentially lose my life savings) based on a circumstances beyond my control is not something I am willing to chance... even if it is a one in a million chance. For personal use, I have done things for myself, that I would not do for a customer. As always, the decision is yours as is the outcome.

i agree completely, and this guy doing the DIY is not a business owner and doesnt have to deal with the things you do, myself being an engineer as well, can handle selecting the right sealant and wiring for the job.

I did a DIY job. It was easy, works well, and saved me money.
On the other hand, I'm still throwing P0440 codes, so I assume I haven't sealed it up quite right yet, so it's not perfect. I've spent half a tube of goop on the hole those wires go through!
