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
