camerondownunder88 Posted September 10, 2006 Report Share Posted September 10, 2006 Hi, I was just tiding up my 4K motor I'm about to put into my KE30 and noticed on the fuel pump for it there is an extra outlet my KE30 pump doesn't have. The 4K is out of a KE70 and the pollution system has been removed. And I belive this line went to a part of the fuel system in the KE70. So here is a photo of the pump on the 4K: (the extra outlet is pointing away from the block on the top of the pump) Now the one on my 3K in the KE30 doesn't have this out let yet a blocked hole for one. And both fuel pumps work. So here is a picture of the one on my 3K for comparison: So my main question is what is this outlet for and when was it introduced into the corolla?

Xany Posted September 10, 2006 Report Share Posted September 10, 2006 (edited) its a return line for feeding excess fuel back to the tank. Edited September 10, 2006 by Xany Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted September 10, 2006 Author Report Share Posted September 10, 2006 So would it be best to use the pump off my 3K or 4K when I do the engine change? Cameron Quote Link to comment Share on other sites More sharing options...
Xany Posted September 10, 2006 Report Share Posted September 10, 2006 doesnt really matter....i'd be using the 3K one though if you arent going to run a return line. Quote Link to comment Share on other sites More sharing options...
Rolla__Boy Posted September 12, 2006 Report Share Posted September 12, 2006 Use the 4K one, and run the return line from the fuel pump into the cabin so you can make a "cool flamethrower" for those annoying cyclists that forget how to use a bike path Quote Link to comment Share on other sites More sharing options...
