I would just like to clarify that for the Evo 8/9, the ECU does not prime the fuel pump prior to turning the key to the start position. (The Evo 10 does, however, prime the pump.)

Can you use this pump with both e85 and 93 for those looking to run dual maps?

stupid question, evo 8s dont prime until you are actively starting the car?

Excellent write up, thanks for your time and info sharing.
on a side note, the wiring doesn't seem as bad as I thought, but what is the purpose of it? why did you choose the cut connector that came with the pump and optioned to use the stock one I suppose?

Just did this install and i can answer that question. the connector that comes with the kit doesn't fit into the evo housing. It is a universal pump and there isn't actually and install kit for it (yet).

My install went great. It is a snug fit getting the lower housing to latch on but i got it and used a worm clamp for extra measure.

I was tuned on 93 w/ a dw300 and 1250 fic bluemax. afr at wot was 11.5.. now with this pump it is 10. well thats as far as the aem gauge will read but i'm sure its richer than that.

That just means that this pump is flowing alot! lol

I see your running close to 60psi at the rail on idle. I'm feeding 2150's and I'm thinking about drilling out the orifice in the return. Have you modified your return? Or just ran increased fuel pressure.

Thanks for the info!
So I purchased a gasoline one off another member on here, and the connector that came with the pump seems to fit the one on the housing perfectly. granted it may have 0.5-1.0mm worth of play/wiggle but I suppose that's acceptable?

Also, the pump didn't come with the same connector the OP of this thread is showing, see below for a comparison;

update:
I am running into a fitment issue with the gasoline version due to its output nozzle being shorter. So it can't reach into the black grommet. Anyone else have experienced this?
see pics below;

you'll need to dremel the upper edge to get the pump to set down low enough to get the end cap on.
too me about 20 min and I was going slow.
so on you pic the edge that's hitting the housing, grind that down to just before the upper hook that holds the end cap in place and widen it out alittle as well.
there's another thread that shows how to do this with pics.
I also have a full blown dual fuel pump anodized purple so that it will not pit inside a tank of e85, includes two new pumps and new an fittings (that were an additional $125.00 and plus two new walbros 255s90.00 each) for $450.00 plus paypal and shipping. save over $100.00

the op cut his all the way down to the first clip you pic shows like you still have some more to cut off the housing. than you'll get that extra 10 mm your looking for.

I ended up using a 7/64 drill bit to bore the return line office just a bit. Dropped the fuel pressure through my fuel lab regulator from ~65psi down to 38psi on spring pressure. Then I used the regulator to jack it up to 45psi at idle.
