LS1 Fuel Pump Draw/fuse?
I have a 2002 LS1 going into my '69 and installed the stock in tank fuel pump.
I'm wiring everything up and i was told I needed to find my own 12v source and put an in line fuse at whatever the draw rating of the pump is.
Just curious if anyone here knew how much the LS1 fuel pump draws?

Also, the pump should receive 12 volts from a relay, and said relay should be energized from an ignition(key on) 12 volt source.

Instead of inquiring how much current the pump draws, wouldn't it be more efficient to just size the fuse the same as the vehicle the pump was removed from?

What size does the corvette use?
This 12v line says it needs to be constant power and is the wire that is being fed into the relay...
the other two wires of the relay are already pre-wired. the 4th is the wire going to the pump...

I don't have an 2002 Trans Am so I have no clue what fuse they use...

cool. so it looks like a 20a will do nicely.
here's another techy question.
You're suppose to fuse as close to the power as possible right? But there's a spare fuse spot in the fuse block supplied with my harness. I could use it instead of an inline fuse but this would place the fuse about as close to the relay as you can pretty much get....matter a huge deal?
