Me and my bro plan on doing this DIY. I will be ordering the pump today from Amazon: http://smile.amazon.com/Walbro-TIA48...rds=walbro+450

We should have it all done in 2-3 weeks (I'm going out of town). I'll try to make sure to take plenty of pictures and maybe video.

Shoot me a PM if you have any questions along the way. Let's get a tutorial up!

I wish I know there was going to be so much interest before hand. Would have made a detailed tutorial.

What Ethanol concentration can you run with this?

Venturi keeps the bucket full even when very low on gas so then your pump doesnt run hot or you run out of gas prematurely. I use to make these kits you the oem pump with a walbro 450 in "series" better than just one pump. I've been running mine going on 2yrs no problems. Every car is different though thats the need to tune and datlog cannot be over emphasized. You stop adding e85 when your pump starts suffering psi goes to low. You can see that from the datalogs. These kits retain oem reliability as I don't touch anything in the oem basket

in my opinion you guys are making this more complex than it needs to be...
just swap the pump out, leave everything else intact. there is a one way flap on the underside of the venturi/bucket and there are two hoses on top (one being the return from the regulator) that are pouring fuel into the bucket constantly.

this is not my first fuel pump setup. did a near identical stock bucket conversion on my brothers ls1 ss camaro, ran that intank walbro 255 for around 9 years, before selling the car - zero issues. the vehicle was full bolt-on running a supercharger, pump hotwire kit, and green top injectors. the second setup i did was on my 65 chevelle which i had done a backyard LSx 6.0L swap into. welded sump to filter to gsl walbro inline and an stainless braided lines throughout.

i've ran 4 full tanks so far on the bmw, all down to "---- mls".

leave it stock, do the swap, or buy a pre-converted "stage 2" with the same pump... doesn't matter to me. i have nothing to sell you.

EDIT... nvm

[matthewo]

Lol Internet forums are great. It really doesn't mater if you cured cancer someone is going to argue with you and say they have a better way. Regardless I'm not an expert on the subject so I will stay out of it. I just bought the stage 2 cause I wanted a pre made drop in. I was thinking of doing it but it seems like every project I do takes longer and is more stressful then imagined so I went the easy way on it

So where are your pics, the entire idea behind two pumps rather than one is your able to have more volume which you definitely need when you run high concentration of e85. I'm not selling anything either but i have done this far to many times and I run 100% e85. So good luck on not having the bucket full and lets see how long that walbro lasts.

this is nothing new, I think Terry from BMS was one of the first to do this... like over 2 years ago. Swapping out the pump is easy and cheap. Paying for the tow truck and the inconvenience that comes with that is why Terry deleted that thread. If you are just doing a straight swap, its only a matter of time before a clamp slips or a hose burst. Have fun with that.

07tundra has been using the 455 pump for a while. I think with his set up, if the 455 fails, the stock pump will still save you from being stranded. My question is did you have to do anything to get sufficient power to the pump?

I've been running the 255lph inline pump, with a half dead stock LPFP on E60 and while it runs fine, every once in a while I get terrible long cranks... I think because the pump doesn't prime correctly. I have a 455 that's just been sitting, would like to put it to use.

This!

I guess the fuel it stage 2 has a few additional parts changed, but I don't see how it would overcome some of the concerns you brought up, but a lot of people are running the fuel it stage 2 without issues.

[mastamike911]

matthewo , I'd be interested to know what "additional parts" the Fuel-It Stage 2 has.

this is no different than the Stage 2 kit from Fuel-It. What you are running is an inline pump. 2 different things.

These Walbro 450s have been running for years in the e9xs with not many issues.

At least you'll know Jeff will ship it right away and you'll receive the correct part.
+1 for customer service too.

jeff is great, plus if there is issue he will take care of it.

Post pic of the custom plug and play fuel outlet please. If your going to compare the best kit on this platform to yours you need to post pics.

Thanks

Im running the Stage 2 Kit from Steve. What I was trying to get at was 07Tundra was comparing his multipump kit to the stage 2 kit. Completely different things.

I'm just letting people know that if they decide to throw the 450 pump in, they run the risk of being stranded on the side of the road... I too would like to know what's in the Fuel It stage 2 kit as I doubt it is $300 worth of extra parts. That being said, I'd rather pay the extra $300 and have peace of mind knowing that my fuel hose won't randomly burst.

why would a properly rated fuel-injection hose just "burst"... the metal 5/16 barb isn't going to fail... neither are the 6 clamps (2 per connection)...

i don't get it.

I'm not comparing anything at all I said is that this is how i ran mine and I've had for a long while now with no problems, leaving the venturi as is if you don't have a venturi solution.....Gotta love this place putting words in mouth. I don't think so. Someone had said you dont need the venturi as you have 2 hoses feeding the bucket. So where did you get that I'm comparing? Please don't assume!
