Also moar vids!

No, went straight to the intake.

More videos will be coming, hopefully with clutch install this weekend, everything will be set.

Sweet looking forward to it! Might place my deposit for a kit today.

Can you hear turbo spool at all or is it pure exhaust sound?

So I know there are a lot of people wanting more information on fuel pump install.

I initially installed the Visconti pump and had some fuel issues. I removed it yesterday and installed the DW pump and noticed the issues I were having were NOT because of the Visconti pump, but install error (I take the blame for not veryfing ).

Use this post as reference for things that need to be checked are in properly before finishing the install.

I will include a series of pics to explain why i had fuel issues. There is a DIY install on fuel pump, so for explanation on how to remove and re-install it, please refer to that guide. Keep note that there is a difference between the DW pump and ALL other pumps available to date. All other pumps (be it Full Blown, Visconti, etc, etc...) are longer than the OEM pump and don't really fit the OEM canister. You need to workaround that to make it fit. More explanatin below.

So this is the way the Fuel Pump Assembly should look. Notice on the right hand pic, the clips are all the way down and "clipping" like they should.



Now look at my canister yesterday. Unfortunately I cut the Zip ties before taking the pic, but you can see where I needed to drill holes to hold the canister with the bigger fuel pump in place. Zip tie goes in the holes and up around the clip to hold it. I had to do this in the three clip locations (I took pic of each of them but for some reason I see only one in the phone gallery. )



Next pic is the DW pump assembled and inside its assembly ready to go inside the canister.



Now pay VERY close attention to the below pic. Notice the fuel like inside the canister that looks coming off that green "dot". That line was routed differently when I opened my canister yesterday. The routing it had taken had it pinched against one of the clips. What this did was sometimes when I drove, the car behaved awesome with no issue. BUT other times, it would jerk and seem to stall even giving it gas, because of gasoline starvation. That fuel line NEEDS to be routed towards the bottom of the can, not above and U shaped.



Now notice how the black and red cables have a little spot to be routed. It is EXTREMELY important to route all fuel lines and power cable the proper way becuase they will get pinched if out of place.



Notice how the cables are around the black fuel line. they CANNOT go below the line because when you bolt teh assembly you push it down completely and that will pinch the black line against the power lines.



Its hard to tell, but if you look at the right hand side of the pic, there is a clip that looks to be just above where the black and red cables connect. Now from the clip look left and you will see that the clip continues left all the way to the canister. notice the black fuel line below. This is the pinch point I had with the line. Instead of routing it below, it was bent right there in a U shape.



One more look at the cable routing (It is pretty well explained in the DW pump instructions see above link).



Finally, this is more or less what the assembly looks at the end. notice that with the DW pump, the clips DO CLIP in place, so no zip ties needed. Also, the DW pump includes the conector to plug and play, unlike all other pumps that you need to solder or crimp cables.



All in all, this is not a hard task by any stretch of the imagination BUT it is one of this tasks that you need to pay extremely close attention to detail.

The difference between the DW pump and all others is included connector for plug and play and the lenght is short enough for the pump assembly to clip in place (just like the OEM one). No need for zip ties or other work around to make it fit.

To install the Full Blown, Visconti or other larger fuel pumps, just drill the little holes and zip tie to them. There ARE Chemical resistant Zip Ties (can be found in one of the most awesome websites, Mcmaster-carr, click link)

The pros of the bigger pumps is higher fuel volume (at 280-290 LPH) compared to the DW 265 (yep you guessed right, 265 LPH). Also, for some reason DW does not have the most stellar reviews out there, while I can at least vouch for the Visconti pump that its top notch VERY high quality and great reviews.


Hope to have helped!! Hit me with questions!!

You can hear the turbo spool SO AWESOME!! For real, its pure sex! Maybe its the intake that enhance it, but I didn't try with original box to see the difference.

Good job on the pump write up.

Picking between this and the FBM kit is so tough, thanks for all the writeups and progress updates.

BTW how loud is this setup compared to your old 2.5 inch nameless setup?

Its a a little louder in some areas and a little quieter in others. Overall like it a lot and this is coming from someone that really hates loud exhausts.

Also, I think I may be upgrading engine mounts too. I actually think I hear them flexing under full boost!

Keep on trucking buddy!!

I hope they help out the community to learn from my mistakes. I have had some minor issues (Wastegate not opening, exhaust leak) that should be taken care of this weekend. I can't wait to finally drive the car like I'm supposed to.

That is the price of DIY, with the kicker that work this days is not allowing me any free time to work on it. So even though I have had the kit installed for like 3 weeks, I literally have not yet redlined the car.

If I had taken it to a shop, any issue would have been covered by now. But thats a price I was willing to pay! I could also do the clutch swap, but I'm tired of using all free time to work on the car. Taking it to a shop and hope to have it all taken care of, including the exhaust leak. For the WG, I will be swapping the 5 psi gate in today, to see it properly open.

Very cool info here, thanks for all the write ups and experiences. Something tells me I will be referring back to your fuel pump post.

Another one bites the dust, and another ones gone, and another ones gone, and another one bites the dust.

LOL, I need a week of vacation to finish it up!

[King Tut]

Then you will need a week of vacation to recover from your week of vacation, haha. I bet I could get all that stuff done in a day. I love working on cars though. I am doing belts and water pump on a Miata on Friday/Saturday and a water/meth kit on a WRX on Saturday. Then I still need to do prep on my SpecE30 for the first weekend in May.
