Default dw65 failure rate?

Interestingly I feel as though I haven't heard any negative comments on dw65 fuel pumps. I live relatively close to IAG Performance (45 min drive) and i went to discuss a pro tune and a potential list of mods that I should consider before getting a pro tune (I'm already TP stage 2 w/intake). I'm awaiting the highly anticipated GS tmic, I have a GS ebcs, and I was thinking fuel pump. They recommended an EWG but I want to keep my car quiet (stock cbe). Well the discussion came to a point of the fuel pump, I remember seeing they used to carry dw65 fuel pumps, but they said they took them off the shelves because they claim they saw enough failed pumps that they stopped carrying and recommended walbro pumps with the hack and chop housing job.

I don't like the idea of the mangling my fuel pump housing to fit the walbro pump. And I notice that the dw65 come with a 3 year no fault warranty. Does IAG know something that the rest of us don't or could it be more of a corporate move and for whatever reason are pushing for walbro's over deatschwerks? They even said if I were to go with a dw65 they would make me sign a waiver acknowledging the risk associated with using that particular fuel pump.

Interesting to say the least I would like to hear your opinions on the matter. Maybe I'm completely wrong an IAG is completely right, but I would like to be told that by a third party rather than just blindly taking their word on it.

IAG recommended the Walbro over the DW for me too. On top of their owner/tuner's thinking that the DW unit isnt great, I have seen a few posts of the DWs having issues on here recently.

My story, freshly rebuilt motor with new forged pistons + "stage 2" level mods + Spearco top mount. During tuning, my stock pump was showing signs of failure, massive pressure drops at higher rpms, stumbling, etc. I couldnt just leave it like that, so I had them install the Walbro right there. I think they got it done in about 1.5-2hrs, maybe less. I think the installed price between the two was pretty close (Walbro = cheaper, more labor; DW = more expensive, less labor), so i headed their recommendation and went with what IAG and their tuner felt was a better unit.

If you're worried about "hacking up" your fuel system, just have them install it. It's worth the piece of mind and they know what they are doing.

Not to disparage any shop that has a preference, but MOST shops have a boiling point when it comes to certain products. This can happen in two ways that I've seen:

1. A shop will try out Koolaid Injectors and love them. They recommend and sell a buttload of those injectors. After time, the injectors tend to get clogged easily and/or Corporate at Koolaid makes an unsocialized change to the product that causes issues during tuning. Sometimes the timeline of reliability and product changes turn a shop off to an otherwise great product.
2. A shop will have a few issues with Koolaid Injectors. These issues either rustle the jimmies of the shop or customer(s) to the point where the shop doesn't want anything to do with them. Let's say they experienced a couple of simple failures, then the shop owner's best friend is at the tail end of a $10,000 build and an injector lets go and you end up with a furious customer. Or you are equipping a sponsored race team and their engines have to built, come hell or high water, by June 15th for a major race and injector issues creep up and the team misses the deadline due to parts.

This doesn't mean that those parts ARE a horror show as you are talking about a limited sample size of one shop. But, if that shop is your go to shop, you really should play nice and go with what they recommend. And there is nothing wrong with a "hacked" Walbro to use instead as sometimes the simple solution to a problem though not OEM, is just as good as a "better" solution.

my personal experience with the DW65c Pumps is that they are not very good.

I went through 2 of them b/c they were nothing but tuning nightmares. (not tuned at IAG)
Swapped over to a Walbro and everything was perfect...

Its not much "Hacking" as long as you take your time and do it correctly and not "hack it up". Its nice to have a drop in replacement but when it does not work correctly and can have the potential to cause engine damage, why risk it?

Also while i was getting tuned there were two other customers that were fighting tuning issues with DW pumps also.. FYI.

I think with that testimonial and the fact that installed it's the same price, and the fact that IAG is insisting on the walbro, that's enough for me to go with the walbro. Thanks fella's. When in doubt trust the tuner I guess...

My tuner rec. the dw65c to me, and said he's never seen one fail. And he's one of the bigger tuners here in Cali. So I'm trusting his opinion.

Funny that I am came across this thread... I called IAG for a quote on some labor and questions about my build. They also stated that they have had some failures from the DW65c Fuel pump. I had already purchased the fuel pump and said " I would need to sign a waiver to install the pump...." The last thing I want is a $100-$140 part to ruin my engine.

I ended up selling a brand new fuel pump and buying the Walbro. The only reason I bought the DW65c is because I wanted to run E85. But in MD its hard to find where I live.

I have used Walbro 255 fuel pumps on my Evo's and Civic in the past and never had an issue.

I used a DW65 at first on my setup, and while it didn't fail, it definitely did not perform up to par. Long story short it barely flowed more fuel than the stock fuel pump, so I switched out to an Aeromotive 340 and called it a day.

I feel like the quality of DW has gone down over the last few years, it's unfortunate because i used to recommend them to everyone, now there's just no way i could do that.

Ive used both on several cars and im currently running a 65c in my WRX. Ive never had any issues with either and I live about 10 minutes from DW, they are a great bunch of guys and stand behind their products. Anything and everything will and can fail sooner or later. Both are good pumps and I wouldn't stress about putting either in my cars.

Going on 2 years with my DW65c. I bought it for the main reason you stated - just wanted a drop-in FP with no modding needed. No complaints at all. I'd buy it again.

I was looking at installing a DW65C as well and guess what......my tuner suggested I stay away from this pump as well. Said they have seen some failures and many "inconsistencies" with these DW pumps.

My mind is made up.

Read on here recently a guy who auto crosses a lot was having no issues on the street with this pump but on track days he had problems galore, switched to the walbro and had no further issues.
