but i guess use it until you can upgrade. I will say that i was using the 2.87 pulley with DW 440 injectors, walbro, and CJM stage 0 return kit with no fueling issues at all if you needed advice on a cheap way to upgrade.

I actually still have the rear-rail adapter for that return kit. I can cut you a deal on it then all you would need is a 6an stainless line for the return, the correction kit, and a FPR and you will be in business.

He used an in tank fmu. Im happy with my car, I don't think I'll ever move to the 2.87.

I took the fmu apart and it looks like it failed due to water getting into the vent on top. There was a lot of rust in the center section that is open to atmosphere

Did your original fmu have a hose coming off the vent and curved downward?

Sounds like whatever happened, you are good to go with that new fmu. Ita nice to hear of a sc setup out of the box that has run like a champ for as long as yours has.
