Fine bit of detective work going on there KillaB, probably need to get the details 'stickied' when you have finished for the rest of us when we need to replace these!

 

Hi KillaB, Came across this replacement pump on 'the bay'.

Not having taken this apart and taking note of your comment on the connector. Would this be a like for like replacement for just the pump as the connector looks kind of similar?

 

@Al1040, I never did find a rhyme or reason to why some pumps include the extra connector cutouts and others don't. That pump (and many many others) look like they will work just fine.
I'm probably going to be picking up a Spectra Premium SP1126.

Quantum are the only company I could find offering a like for like aftermarket fuel filter, as well as compatible tank seals and fuel strainers.

I know it's overkill, but I'll likely be pairing the SP1126 with a K&N PF-1300 similar to @Matteo in the previous thread I linked to here.
Most other "cheap" filters are not designed for EFI systems, so I'm a little worried to use one. Here's a little more discussion on that topic: https://www.stromtrooper.com/threads...2#post-5408029

I wonder if anyone has ever attempted relocating the fuel filter on the F4i (if there's even space) to outside of the tank?
