Using an A1000 pump w/o sumping, heres my idea...

blackfin, i used to live near you... north, off 113th street and ulmerton.
weldons are expensive, twice as much as an A1000. the magnafuel, i havent heard of. im unsure of their track record and such. unless they are a rebadged unit made by holley/magnetti marelli or whomever.
but, randy's 2cents intrigues me. i always thought A1000's were strictly external. what happens when you run empty and the fuel level is at or below the inlet of the pump? im trying to picture mounting it vertically like a stock pump on the stock hanger with some kind of sock mounted to the inlet... since they arent self priming, how would it perform with a low fuel level...

regarding fuel movement in the tank while cornering, you could always put foam in your tank: http://store.summitracing.com/partd...part=RCI-7050A&N=700+-118218+115&autoview=sku
yeah... but for anyone trying to make over 450hp (like a good portion of us here and most of us in this thread) foam is not 100% safe with all race fuels 
flubyux2, still in the area? Your avatar says St. Pete.
Agree Weldons are pricey. I have no personal or second hand experience with Magnafuel pumps and hardly anyone is using them. But from what I have found through various Google searches they seem to make a good pump that is par with the A-1000, maybe better.

nah, i moved further north, to the north side of pasco county.
i wonder if those magnafuels would be more reliable than an A1K.

2 words to solve any problems with the A1000 pump with or without a sump.
Surge tank . The surge tank stores a small amount of fuel for the high pressure pump to pick up if flow from the main tank is interrupted for any reason.
Edit: When you decide to check the pump or even if it fails, having it as an external has it's benefits

Weird, I seem to remember that being suggested on the first page.

I run a surge tank on my supra. It's fed by an intank walbro, and has the FPR return connected to it as well. It then uses the stock return line to connect it to the gas tank. This way there is no pressure on the system, once the tank fills it pushes the extra gas back to the gas tank.
While it's no the ideal setup, it works. Your fear is valid about the surge tank running out of fuel but you have to figure that the large pump drawing from the surge tank would have to drink the fuel faster than a 255 at 0 PSI can supply (which is a lot.. not to mention the fuel the FPR is bypassing). I know with my setup it's impossible, so thats why I've crunched the numbers.
I was worried about this as well because we race it's top end, usually 60-140+. I havn't had any issues with leaning out yet. But I also have a huge surge tank (3.5 liters I think?).
While this setup works.. if I had to do it over again I'd just do a fuel cell. This was pretty quick and easy considering. Anyways, I just figured I'd share my experience.
and i am going to 2nd that reminder
surge tank,
but then again. Duane you run a sump and have tracked the car. any issue?

any issue? Duane, that wasn't directed at you. It was because when I mentioned the idea before, some people didn't seem to like the idea.

why not run surge tank and 2 walabros i was going to do this but found a1000 for cheep
ps a1000s don't last that long that is why is it good idea to get fule pump controler

How do they "not last so long" ? Any factual information here to back this up? (curious)
I have had mine on my car for over 2 years before selling it. (with no controller) I have driven 3200 mile round trips and many more trips countless times back and forth to Oregon, California and Seattle.
I now run an Eliminator Aeromotive pump since I have more hp that requires a higher flowing unit.

figgie said:Duane, WELDON...... last pump you will EVER buy!
Why change if it works fine?
But then again I can do it just because right? :biglaugh:
if i remmber right you don't drive your car much
but yes they don't last that long this was told to me by them when i was looking into pumps and they recomend me to get fule pump controler if i was useing ti as daily driver
plus it will not be noisey as well when just cruseing around

You obviously don't have a good memory then. (or even know me that well) The only time that I haven't driven my car much is this year due to the new build that was done. I drive my car A "LOT". As stated but will mention again; I drove to Vegas not once but twice with the A1000 then to California a few times, Oregon and MANY MANY other places. Ask anyone that knows me and my car.
NashMan said:
Funny thing you say that they told you that they won't last long. I highly doubt they would say this since it wouldn't be a very good sales tactic.
Daily driving? I drove mine almost every day when I was sporting the A1000 and it was great! I too have heard many things about "issues" with these pumps but I have done enough driving to prove that these are a great pump for what ever your need.NashMan said:
My current and new pump is the Eliminator from Aeromotive. My pump may seem loud outside but you can barely hear it when cruising. (inside)
On a more positive note: Aeromotive is a great company that has awesome tech support as well. I spoke with them both on the phone and by email with my entire fuel system. They also gave me tips on how to make the most of the system.
