$OLD: Brand new fuel pump internals for MS3/6/CX-7 - $125

[JohnnyT]

Up for sale is a brand new set of CDI fuel pump internals - these are the 2nd version of the very successful mrlilguy fuel pump internals. If you're seeing low fuel pressure drops, these are the ticket. If you're stuttering, or getting fuel cut - these will solve the issue. There's been a bit of drama regarding these, and just about every other set of internals and it's been confirmed that this is largely due to installation error. If you've seen the how-to's on these installs many have said to use gasoline to lubricate - USE OIL!!! Gas is not a lubricant people. See the thread below on the success others have seen with these internals by USING OIL during install:

Price is $125. $130 if you need it shipped.

There is absolutely no sense in buying the CP-e pump for nearly 5x the price of these internals. It takes no more than an hour or so to install and if installed correctly you'll see pressures around 1,800psi @ WOT.

Yeh, if you need compliance pics I'll post 'em up...

When these were essentially the only new option, I bought them but I didn't really NEED them. The majority of people who installed them using gasoline had their internals fail. Speculation was rampant, and then the KMD's came out and were supposedly that much better. I got a set of KMDs instead, installed them a few weeks later when the gas install was known as the major cause of the failure (not the internals themselves).

Now, I've got this set, and know a good # of people running these CDI's with success.
