If you use correct fuel line and clamps along with install injectors correctly I don't see much that could go wrong. MPI comes stock on ROW models, we're just changing the injector size and when it fires.Yea I I guess the assumption here is a big one but my question is assuming everything is installed correctly. You don't have to look too hard to find people having issues with both but troubleshooting and fixing a LPFP / MPI setup seems more of a pain than swapping out a HPFP.
I guess the real question is if LPFP/MPI setups on this platform have gotten to the point where they are relatively trouble free when installed correctly and when not pushed to their limits.
I've been trouble free other than a runner flap code that popped recently. Using a China euro mani, so more than likely need to swap the diaphragm from my stock unit.
Other than that I've only heard of the rare injector issue, but you also get those with your DI injectors.
Personally it seems like 1 out of every 4 autotech posts is a failure. I'm sure a lot of that is on the install and not the part, but I'm also 1.8 so HPFP wasn't really an option until recently.
As for LPFP. Go RS3, don't bother swapping a new pump in your existing basket and that'll remove almost all possible issues. Most lpfp problems are install related.
