Customer Reviews
Bought this for my 2019 230i and put 500 miles on it before writing a review... it's been working perfectly with no issues, was incredibly easy and straightforward to install, and solves the issue of the oem hpfp being incapable of supplying enough fuel when tuned for full e85. Gonna continue buying from IPOS exclusively
I got this pump a few weeks ago for me 430 that is running a flex fuel e60 tune, the install was a little stressful until I got the line from the rail onto the hpfp, (it helped a lot to grinde down the engine cover post a little bit barely needed to bend the line then) after that it was pretty simple and the pump is not stressed at the 60% ethanol level, it also does not make a lot of noise no more then the stock pump, this is a better option then the TU pump on the b48 motor for sure
