Well i actually install the fuel pump onto the hanger and ran the wires, its ready to drop into the tank now.
the stock fuel pump wires were actually rivited to the hanger, so i had to drill them out and mount the new terminals w/ self-tapping screws.
Its as good as OEM, only Better. the next step is to run the 4 AWG cable to the battery, then the 8 AWG from the gold-plated terminal block, then the 30A relay, and use the stock fuel pump wire harness to toggle the Relay.

The reason you haven't met many people who "knew" that the electrons "ride on the surface" is because that's not really true.
Electrons travel on the surface of a metal in a static field, however with a constant current, the moving electrons are spread throughout the cross section. With an oscillating current, at a high frequency, the conducting electrons are located on the outer edge of the wire. So often, the electrons do travel on the surface, but not always.
That's why you haven't run into too many people who know that bit of trivia as you describe it.

you joined TR just to telll me that???
I was hoping you had something useful to add to this thread about fuel pump rewiring.
anyways, current draw is based off of mechanical load placed on the electrical motor. Fuel pressure changes more often than you can count on one hand every second, and it can change as much as ~20 psi in just that one second, which translates into ALOT of load differential being placed on the electric motor that drives the pumping mechanism; gears. this means that the current draw is not linear and can 'oscillate' quite a bit... so going by what you just said, the electrons will spend MOST of their time riding on the surface because the current oscillates.
btw, what is the frequency of a ~12v DC system? i know that standard household 120v AC is 60Hz, but i dont recall what 12v-16v DC current frequency is.
btw, according to your statement, my previous post is True, but not 100% of the time. you said :
THen you said:
which means that the REST of the time, my statement is false. but for the time that current is NOT Constant, Im right and my previous statement is true.
anyways, i appreciate your input. now i will meet more people who know that electrons ride on the surface of the conductor when the current draw is NOT static, but ride thrut he whole conductor when the current draw IS static.

normal DSM style, or my own supra-brand of rewire? this rewire took me a full 7-8 hours, including trips to Best Buy, Circuit City and finally Sound advice to get the 80A inline fuse for the fuel pump power cable (Speaker Amp cable).
DSM style would probably be the same amount of time, just using smaller stuff... maybe even easier and less custom stuff.

dude hit me up on aim

lol... im just clickin around, dont feel like hoppin on Aim right this second.
but, you only have 4 cylinders... you only need 10AWG from the battery to your stock fuel pump harness. just need a 30A fusible Link from radio shack or something... 15 ft of red 10AWG, 4 feet of Black 10AWG, appropriate ring terminals. I personally would rather solder the 10AWG to the stock fuel pump harness so that you can maintain the connector and have the ease of connection. then you need some female blade/spade connectors and a 30A automotive relay, SPST type. Its a breeze, especialy on your car. read the VFAQ to get a feel of what its like and see what youll be lookin at when you look at your car.
right meow... im pretty busy and hardly get time off for myself... im still backed up on projects right now. i still have alot of stuff that needs to be done:
UICP for the supra
BOV install for the supra
BOV modification; Dejon Tool style
Fuel rail return line mod for the supra
Bumper cutting for the talon
reassembling the talon
Replace alternator in supra
Replace alternator in the FC
Replace leaky valve cover on Talon
Pick up Supra rear diff from Agent 89
Replace rear diff in my supra
Build custom 3" exhaust for supra
Build custom N1 style muffler from Dynomax Race Bullet.
stupid projects...

I supervised this job and it took probably less than 45 mintues.
So whats your point. someone did something better than its normally done?
btw, rewires are a good idea.
