Fellas, i do appreciate all the help i have gotten here from everybody, trust me, i have had no luck finding any info at all regarding the matter, All the info here is what is what i got.

2tone, i did think about the e85 stock pump and getting into that, but in my application, id be purchasing two pumps and it would cost me way more than getting one pump.

With one pump, i have to see what works or doesnt since there is this module talk and im not sure what it means.

 

Buddy a mine in the performance industry recommended this, its for a GM application:

Aeromotive | 11169 - 340 Stealth Fuel Pump (GM)

What do you guys think?

 

Im conufused on why you say you would have to buy 2 pumps? I was throwing out the option (i know it is not a viable option to some people because its stock gm crap) of just buying a new pump for a flex fuel truck and dropping it in. That would require zero modifications and be a drop in fix

 

2tone, i only stated that because earlier on in the thready you mentioned " i would go get a flex fuel pump and put a BAP on it and call it good".

I dont even know what my stock non flex fuel pump can handle...so far it runs great, even tho its never been on the dyno nor do i have a fuel gauge on it...

Id like to upgrade only for the safety factor. Its just a car with a blower and headers for now...

 

So i think im going to try a 340 pump...now next question that comes up is the inlet...i see some are centered, and some are offset to the left or right...any idea what GMs would need?

Thanks guys!

 

Damn it I wish I could remember... pretty sure mine was offset. That being said its a flexible hose that is being attached so its not that important.

 

LOL remember darn it!!!!!!!!

 

im in the same boat as you Smokymance, even though i have a flex fuel pump im already maxing that out, i dont want to put a BAP.. Bump for a answer sorry if i wasn't any help

 

After many questions and bothering many people...im coming to a conclusion that the 320 or so pumps will be ok w the stock regulator...

so far there is many companies that make the 320 or so pumps...all seem to have great reviews...

I think ill looking to get this pump:

they also make a 320 e85 pump for a lil more

http://www.summitracing.com/parts/avm-50-1200

Those i believe will work good with a lil bit of bucket work...

Im also thinking of getting a hot wire kit from racetronix but they seem to have many options im not familiar with

 

So i ended up getting the AEM 50-1000 pump...and it worked out great...

Here are some pics of the swap. Im not sure if i got lucky, but it worked out fantastic on my SUV fuel tank bucket assy...all i needed to do is trim up the bucket holes, where the top grey piece tabs clip onto. THis way it allows more room for the new pump. New pump sits about 8mm taller than the OEM pump...but everything else is identical: inlet, outlet, overall outer diameter...I even used the stock O-ring that connects it to the top grey piece where it feeds the system. Didnt use any of the AEM kit hoses or filters....pictures speak for themselves. Hope this helps someone with their build

Kinda disapointed with the surface rust on the tank but what you gonna do.


Stock assy was out pretty easy...disconnected the fuel level sensor so i can work on it without removing the top lines. they were in there due to the rust.


These are the tabs you have to pop open to split the bottom at top assy appart


This is where i stopped and thought about it for a second so i didnt break anything. The two rods holding the lower to the top with the two springs looked like they were cut vertically and expanded to hold the bottom in...kinda hard to get in there w a needle nose to flatten them out so i just dremeled them down a bit...I expanded them the same way when i put it back together...




Stock pump vs AEM 320, exactly 8mm taller body wize, where it counts as you will notice later.


Plug, the same as the stock pump! I cannot do a hot wire kit on the car as the fuel assy is regulated by a module.


THis is where i think i got lucky about this pump...the bottom inlet is the same...which made it work perfect w the stock filter system, so i didnt have to shave down the bucket


I had to trim a few of the legs a tiny bit so it would fit the stock filter exactly the same way the stock pump did...pretty easy


Fit like a glove in the stock filter system


Now since the new pump is slightly taller, the grey part will not fully shut...so i trimmed the holes in the bucket up a few MM so it clicks into place and stays secure. Did this with a flat head screw driver torched so it gives me nice crisp corners.


Fit pretty good. you can tell the little gap between the top of bucket and the grey top assy


Plugged all the leveling sensors etc back together, and shes ready to go!


Did a little cleaning and painting the top of the pump so hopefully it dont rust any further (michigan sals suck!)


She started right up! runs great!

Here is the stock pump assy number just in case! GM 25864571

Hope this helps someone!
