Fuel pump cleaning

[brandonf]

So I took off my fuel pump today to clean it up and swap with the e85 ready o-rings, and I found there's stock internals!? I can't remember if this is the pump I got from Downmented's motor or came with the slightly modified setup from the previous 6 owner, but damn, glad I found this out now.

Next up on the to do list is to check all of the fuel lines/etc to the PI setup (Radium surge tank/return style) and replace them if needed. Install the fuel pump mounting rings (from a Mazda recall), and get new tires. Hopefully this will fix some of my issues and get it drivable again!

Flo!

FattiMotorWorks.com sells the tool to remove and tighten the tank pump ring.

Also, who tf uses stock internals?

Screwdriver and a few careful whacks does the trick for me

I did notice the 1650/1700 fuel pressure in a log, and I only ever had a 0psi base tune on it, but that might help explain why it was breaking up so bad around 3200'ish rpm at WOT, since it's fully loaded with mods. Oh well, I'll grab the CS internals for the DI side, leave the light load to the PI side for now.
