Walbro 400LPH intank pump ? Anyone got any info
Oh boy, some of you guys aren't reading what I am saying. I have the pumps HERE IN THE SHOP. I HAVE ALREADY LOOKED AT MAKING IT WORK. Sheesh, I am trying to tell you guys that by the time you make it actually fit, not make it fit with some "shim" that the cover won't go back on with, but actually make it fit, then the price difference will not warrant using a single pump that flows less than a double pumper........I can't make it any clearer.
Double pumper usage, already thought of it, waiting on our tops to come off the mill to test fit, I see no reason that two of them can't be used other than maybe fitting them through the hole in the top of the tank. Now, the absolute fact is using two of these pumps will require the fuel lines on the car being replaced and a large aftermarket regulator to be used, the siphon would probably need to be eliminated too or highly modified. So now you are talking about complete new fuel system lines and all.............something that the double pumper we designed has pinpointed eliminating. Yes, I'd build it for someone, we have AN fittings for the kits, so you'd just have to buy AN lines/regulator etc. and go through the work of putting it all on.
I will put this out there. 99% or more of you will NEVER need that type of fuel delivery. My car runs 9.0 at 159 on our double pumper with 1200 cc injectors (on gasoline). With the new 2000 cc injectors that work so well, the fuel delivery of the double pumper it's just something that isn't needed.

Sorry, more thoughts. The stock fuel line with our current double pumper is the biggest flow restriction in the system but my car had STOCK lines on it when it ran that 9.0 and had fuel left over with just 1200 cc injectors. So, at some point IF you have a double pumper and start needing more fuel my recommendation is, so you don't destroy a good EVO, take the stock feed line off the car, neatly. Replace it with a rigid 3/8" stainless steel line, in the same holder and up to the frame rail in the engine bay. It is time consuming to do right and you will need a quality tubing bender like Rigid Tool makes. I have a few guys who have gone this route and just used AN line the entire length (which I do not recommend/promote or like) but the IDC's dropped substantially when they did so.
Using our double pumper with just one of these pumps in addition to an already modded Walbro would cause the factory fuel line to become even more of a restriction.....

Ah I see. Thanks for the clarification on double pumper usage. i like the idea of using AN line for the fuel system. Maybe something i may try if i ever need more fuel. so you had 1200cc injectors and what was power at that level that netted you the 9.0? I proudly support your 2.3L and double pumper on my personal car, i really want to get the intercooler along with a few other goodies to match it.
I started an x-specific thread, and Buschur said it would def over-run the stock fpr (or parts pertaining to it).

Hey David a little off topic but is your double pumper available without the pumps? If so how much? Also would it be a bad idea to run a Walbro 255 and a dw pump in your double pumper setup or do both pumps need to match?
i would like to know this as well. i bought a brand new walbro 255 thinking my 8 still had the stock pump in it and low and behold it already had a 255 in it, so i have the pumps and would just need the hanger and everything minus the pumps.
as mentioned a few times, the double pumper with the two walbros in comes with works extremely well. we have made 730+whp on a mustang dyno with the basic double pumper dave builds.
i think we install a double pumper every week, there really is nothing close to it in performance for the price. the DW pump as we have found isn't worth the price. its about the same as a walbro 255, maybe slightly more power (<10whp).
The reason I was asking is because I already have one of each. I suppose I could sell the dw and get another walbro. I already know the 2 walbros in the double pumper is more than enough fuel. I was just wondering if I could use the pumps I have already.

Damn it I should have responded quicker but it took a few minutes to type my post out and gather my thoughts. I was kidding metal
Why don't you recommend doing the AN lines Dave? That's actually what I'm running to my fuel rail...oops? Is it just the looks? The chance of scraping something or puncturing a line? Is this a safety issue or a preference?
By the way I run, as tons of others on this forums do, a Buschur double after trying a FB double which was total crap with issue after issue. It's top notch and the good thing is that you can install it and leave the second pump disconnected until you get around to setting it up and tuning for it if you want for less down time (although it only takes about 10 minutes to run the wire/ground it.

bottom line, come up off the wallet and go with the twin pumps and be done with it
The second pump only runs when you're into boost and need more fuel so you don't have to fuss with the fpr and lines
