Re: 6v fuel pump wiring question

This is turning out to be a good thread. A couple more questions below.
Attached are the two methods from the PAC, Library, Tech Tips, Electric Fuel Pumps article (legacy website, no direct url).
JW, you're probably right. But, if you only use the electric fuel pump intermittently AND have a pressure control gauge on it, the likely hood of pumping fuel into the crankcase from the electric fuel pump is pretty low.
The disadvantage of the parallel line is appearance in the engine compartment above the mechanical fuel pump near the carburetor. I know plenty of people would discount that. Better to have the car safe, running properly and protected. That was my approach for most of the 50-plus years I owned my car to keep it running. Of course, now I have literally paid the price of all those substitutions to re-store it.
Keith...??? FUEL FILTER substitution for CHECK VALVE: I was told the fuel would only flow one way through the fuel filter. If that isn't so, then I need to replace the 2nd fuel filter in the main line with a check valve. I would also move the 1st fuel filter to the tank side of the Tee so it filters for both lines.
???ECH TG6053 is the NAPA 3-way switch I bought. It's 12v, but does that matter for this switch? It took a while to find it and locate one in the Portland area. I drilled a hole in the underside of the dash to the left of the glove box. I'm in the process of wiring it and will take pix tonight.
EDIT:
Kev, I read the info with a strong desire to believe it's true because I wouldn't know any better. Like "the electric fuel pumps will keep spewing gas under the car if you get in an accident with disastrous results. (my paraphrase of many comments on this subject.)"
So yes, I wanted the best info to do it right with greatest safety, least damage, etc. This is what I thought I was doing and getting the necessary equipment to do it.
What is the name and model number of the 6v 3.5psi pump you have? Might help someone who hasn't gone through rigmarole already.
