By reading this article, you will literally save $250.

I have two customers ordering oil pumps.  The one is for an older Lexus SC400 and other is for a new Lexus or Toyota truck and SUV.  The price was huge between the two oil pumps. 

The older Lexus oil pump is about $380 retail and the newer Lexus-Toyota version is only around $85.  From my understanding between 1990 to 1997 oil pump is $380 (part number: 15100-50050) The cheaper version part number is 15100-0F010 and its only $85.  

Initially I couldn’t believe it.  So I called my supplier and want to find out more details between the two. 

The pumps are the exactly the same. 

They are interchangeable. 

However, due a difference in the oil pickup pan, a slight mod is needed.

Below is a typical oil pump for 1990-1997 Lexus LS400 and SC400.  You will notice the recess pin lock in the white circle?  (Part #: 15100-50050)

Here is a picture of the Lexus and Toyota post 1998-2006.  The recess lock was replaced with a large screw.  (Part #: 15100-0F010)

Due to larger screw, the oil pick up pan will not able to mate with the oil pump. 

There are two ways to do this:

1.  You need to grind about 1/4″ off the oil pick up pan.  Its a pretty simple process and the two little bumps are pretty small.  It shouldn’t take more than 10 seconds with a handheld grinder.

2. The second way is to replace the huge ugly bolt with an allen bolt.  An allen bolt has a smaller overall diameter and this will do the trick.

So by following instruction in the page can literally save you about $250.  I have few members using this money-saving mods already.
