2g awd high flow e85 fuel system design

[ishnish]

i don't know of specific threads, just seen it mentioned on here in drag race and build threads, maybe it was the 400lph now that you say something (i didn't even catch the different number and ASSumed the same pump)


also, i wasn't promoting the ful blown dual hanger as i thjink it's way over-priced for what it is.. I built my own and have seen a few other home build parallel pumpsetups in the tank as well, also you can do 2 in-line with each other and get a little less than parallel but more than one pump

No problem I wasn't trying to attack you or anything . I just haven't ready ANYTHING about the pump. It most likely was the 400. Yeah I think one of the biggest problems with the full blown (although you weren't promoting it) is that eviltsi would have to at least 5 gallons of fuel in the tank before the pumps submerged to even pick up. Basically, they didn't sit low enough. I'm not sure if you had this same problem but it's just something I thought people should know.

Walbro E85 Approved 400LPH Pump

Here ya go

Thanks for the link. Idk why it says walbro 400lph e85 instead of 450 though . Maybe that's why I never found that thread .

Not many people are running this pump yet since its so new but buschur on Evo m flow tested the walbro 400 and it made 900 on pump.

Stm also has a 2g running the 400 made 580whp on e85 through a mustang dyno.

The 450lph is supposed to flow even more.

Well I just purchased the pump yesterday so I guess I'll find out how much it flows

I've seen too many posts with people already hitting the flow limits of this pump on E85 and it seems to be sooner than when running 2 wally 255's either in parrallel or series.. think i'll stick with the old tried and trued for now until i see more people flowing big fuel flow with the 450

Saying tried and true makes is sound like walbro dont kno there numbers .... The 450 is RATED for ethanol unlike its predecessors, now if your wally fails walbro will warranty it , instead of say sorry seals have ethanol degridation ## s.o.l.e, and then they get a bad rep . Also the new pump. Chokes after 120psi which is great for those who run 1600cc and want to use high bfp to milk there injectors .... Like honda guys...

 

[hediki12]

Alright, so is this single pump now the best(easiest) option for e85? Would placing an 044 in-line hinder or help the performance of this pump? I imagine it would hinder the flow more than it would help, being that the 044 would then be the pressure pump and the in-tank would primarily just be a lifter pump. Would that be right?

No it wont the wally will push past it. Were it comes in handy i think is past 60-70psi were the bosch will flow more. From that point to 120 psi the bosch will help the wally hold flow at high pressure. Realy good if you have 1600cc and want to milk the raise the bfp to 60 and run up 40psi boost or 70psi bfp and run 40psi and still be in the good zone!

I received mine yesterday. So looking forward to see what it can do. I have a BAP just in case the flow isn't enough. From what I read and the power I'm expecting it won't be needed though.

A few guys around here have the 400lph and a BAP and there making over 600 on a dyno dynamics so hopping for the best I guess.

Gsxtast just checked the data on my sheet and the bosch doesnt flow more till 80psi and thats it at 14v

If you want a little more flow and insurace keep it simple luke the v8 guys a get a kenny bell boost a pump

Thanks! Maybe I'll just do as you suggest, keep it simple and run the new 450 and throw a boost-a-pump on and call it a day.

Ok, so I recieved mine the other day and took my sending unit out. I took the DW300 out.

So what I ordered was the 450lph pump with install kit.

Install kit consisted of 1 6"-8" 5/16 fuel line, 2 worm clamps, sock, 2 wire connectors.

So from what Ive seen even with the install kit I dont get how this is supposed to work? No instructions were sent or anything. The pump does not plug in to the sending unit wires, Am I supposed to splice them in with the wire connectors they sent? Also after looking at it I dont kow how your supposed to even put it in the sending unit You cant get it to fit between the L in the sending unit and the top of the sending unit. Did I get the right thing? I know its a universal pump but this just doesn't make sense.

If anyone has installed this pump please do a write up and link the thread to it in here. TY

Maybe I was just tired but Ill look at it again and make a call to the vender tomorrow.

Wow that has definitely got me scared. I thought installation would be similar to a walbro 255. That's a bummer. Now I have to wait until I get mine to see what's up.

You should take some pics to reference what you mean.

pump and install kit

You must be logged in to view this image or video.

pump with sock they sent. As you can see its going the wrong way so you can use the rubber gromment for the bottom "L" part of the sender.

You must be logged in to view this image or video.

I actually figured the sock thing out. You just dont use the one they send. Just use the stock one. The stock one sticks off the bottom not go across it.

Install kit

May have figured this out to. I think it requires drilling out the top of the sender and stick the nipple of the pump through. Then hook up the rubber line and clamp down. MAYBE???

plug on pump

Does not plug in like a 255 or dw300 so I guess when you get yours LMK what you do.

I guess I dont understand why they sent the huge sock. But since it goes across the bottom of the pump and not stick out like normal. I may have just over thought that part since the sock came with the kit why wouldn't it work?

Went back out put on a stock sock and its fine but the bottom of the 450lph is bigger than the 255lph so the rubber gromet on the bottom that holds the pump is to small. Is it ok to just use the stock one and wedge it tight with the adjustable "L" bracket.

I hope Im helping a little. But to all this is not a drop in affair at least not for me.

Hey cornfed ill buy your dw300 and install kit pm me, your inbox it full.haha

Anyone try to mount this to a 2G sending unit?

 

[ishnish]

Honestly I looked at the pictures and was so lost. I would think the parts that came with it should all be installed when putting it into our system =(. I don't want to have to use old components with new components over a fuel pump. I get my pump on the 18th so hopefully I have some sort of idea when it arrives. Until then, sorry man =(. I hope someone else can chime in right now.

Sorry I didn't realise you came back and posted this. You are definitely helping. I ended up getting my pump a day early . Well since it's a universal install kit maybe you could use the stock one of it works. Are you positive the grommet that came with it is too small?

Just got my pump and by the looks of my temp mock up their is no way you're going to use the rubber bottom mount piece. Instead, clamping to part of the sending unit seems to be the way to go. Now I just have to find someone to machine the -8an bulkhead to fit the fuel sender and I'm good to go.

Anyone have any luck finding the male packard connector yet? I'm on the search

 

[ishnish]

Any luck so far for the two of you?

Haven't really had much time to work on this since school has me pretty busy. I need to find someone to machine my -8AN fitting to fit the walbro 450lph and I was hoping hal would provide more insight but he must be busy.

Soon as I get the packard connector and find someone to machine my fittings I will bolt it up and take pictures.

 

[ishnish]

Cornfed actually has it figured out and will provide a link to it if you PM him

Its easy if youre on a 1g and using stock fuel lines I bought mine with no kit my 255 walbro sock fit perfect too.

Link to the thread I started.

For the fitting your looking for I don't know which one it's is but the the one I linked is -6an which is more than enough I would think for 600+ goal on e85

 

[turboglenn]

I"ve never used thebottom rubber piece and L bracket on my own cars fuel pump installs. I always use a hose clamp just like in the pic, but ONE WORD OF ADVICE about the hose clamp.. DO NOT OVERTIGHTEN it@! YOu can deform the pump body enough to damage the pump very easily, just snug it enough to hold the pump in place if you're not using the fuel line and double hose clamp like shown on the 1g hanger(if you are using that line and 2 clamps then you only need it to stay on and keep the pump from dangling around.).. If you're putting it in and still using the Bell shaped part on the fuel line where the pump is just "pushed in" then make it a little tigher, but overall, I guess the only way to describe it is that i use about 3 times as much force for a radiator hose as i would when using the clamp to hold in a fuel pump.. You just want it where it can't slide down out of the connection to the hanger

That's because they don't make a -8an male to barb bulkhead type fitting. Going from the factory feed to -6an isn't really much of an improvement. This is why I want to go -8an all the way from pump to rail but getting the fitting machined is proving harder than it seems.

No one in that thread is using the proper electrical connector on the new 450lph either.

 

[Cornfed4G64]

What's the proper way to use the plug on the pump? It doesn't connect to the stock sending wires. Have you installed yours yet? I'm still waiting on fittings

Haven't machined my fitting yet but I found the male connector to the walbro
Home » Shop » Connectors / Harnesses » Delphi / Packard » Pigtails » GM Delphi / Packard - 2 way metripack 280 sealed black connector Pigtail

As far as connecting the wires I plan on running larger gauge wires through the sending unit using a cord grip.
