Whats the correct location for mounting an A1000 pump. Its a secondary pump activated via a hobbs style switch

stevieturbo

below level of fuel, between the tank and the engine....although I'd have thought that obvious ?

Or is there more to your question, which given some info is very vague ? And why would you use such a large pump as a secondary ?

Probably best to run a sumped tank, and just ditch the in-tank unit. Just a thought.

This pump with a intank walbro should support any future mods i can throw at it
look at my other post 0 replies though

Some people have bad experiences with the A1000. I dont want my pump to burn up because of bad placement. going to run -10 feed and -8 return. Where under the car would you mount this, anyone have pics? I have a 98 tank I can modify to my needs

stevieturbo

You still havent answered the important questions.

Why are you saying it will be a secondary pump ? That just sounds daft ?

And elaborate more on your setup, and what you are trying to achieve.

A single walbro with a a1000 activated via a hobbs switch, what wrong with this setup? I know its a little over kill

stevieturbo

And once again...no details.

How the hell are you installing the pumps ???

In sereis, in parallel, in the bin ?? HOW ?????

How much power are you dreaming of making ?

And why a small pump, with a big pump...when likely the A1000 alone would do anything you need ??

ok, sorry about that. I have stainless hose for the whole system from the tank to the engine. I replaced the factory fuel filter with an aftermarket one. -6an line from factory in-tank pump and -10 hose with a bulk head adapter on the bottom of the tank to the aeromotive pump. I have a fuel log in the rear to join the two hoses to form one single -10an hose all the way to the engine. The a1000 is activated via hobbs switch in the engine bay. I have an aeromotive fuel pressure regulator mounted on the rails with a -6 return back to the tank via bulkhead adapter.

I dont think i will have room for fuel feed. The fitting sticks out further than I wanted. If it dosen't fit I will get a tee fitting with the female on the middle and switch sides.

stevieturbo

That description is clear as mud. Draw a schematic...because if your description is as I picture it, that is one very weird setup, which makes little sense.

I want to mount my pump here


single in-tank walbro Tee'd together with the A1000, whats so hard about that

stevieturbo

So you have two pumps, running in parallel ?

These then combine into a MASSIVE -10 to the engine ? When really even a -8 is overkill.

I still dont see why you need two pumps, when the Aeromotive will do anything you need ?

And I wouldnt be mounting the Aeromotive fuel pump higher than the level of fuel in the tank. Or any efi pump for that matter.

And you still havent stated what sort of power you are hoping to achieve

Ive had three motors in this car and two turbo systems, I want a fuel system that I will not have to address in the future. I believe i picked -10an because the a1000 has heat and cavitation issues. Is there a way I can mount the aeromotive in-tank if thats all I need? Do I need the controller if I only run the aeromotive. I was shooting for 20 psi on pump gas, daily driver.

stevieturbo

-10 line from tank to pump is fine ( via filter )

-10 from pump to engine like you state is just daft.

The Aeromotive can be used in tank...but I'd imagine that would be very awkard given its physical size.

Maybe consider a Fuelab pump. They are smaller, and seem to offer excellent flow characteristics.

Or a pair of Bosch pumps in tank.

But using a Walbro and an A1000 in parallel, is just an odd combination.

aeromotive wants a really big line for cooling purposes or i can add a fuel cooler

stevieturbo

A big line from pump to engine is pointless.

It will not cool or offer any real benefits. Although it wont do any harm either.

It would be very dumb to fit a cooler in the pressurised side of a fuel system.

And most of the heat imparted to the fuel comes from circulating through the hot fuel rails which are heated by the engine/engine compartment.

Whilst not your car...this is one damn cool looking in-tank Aermomotive !!!

They want a big line feeding the pump; -10 lines and filters, and a -10 post filter. After that, they told me -8 was fine (and the instructions say the same).

The pre pump stuff needs to be big enough to keep the pump fed, to prevent cavitation and damage. Post pump, pressure is pressure (to some point).

This fuel system sounds needlessly complex, no offense. Does the A1000 utilize a check valve (or do you have one for it?). You need to be sure you're not backfeeding fuel through it from that Walbro, when the A1000 isn't active.

Here's a shot of my A1000 placement:



And yes, I do have -10 hose to the front; the setup is designed to be able to utilize two A1000s if I ever decide to go to E85.

system sounds complex but its the same concept in my firebird which has dual walbros(1 hotwire kit on primary pump, secondary pump activates via hobbs switch under the hood and powered by a painless fuel pump wiring kit). The cooler would have to be added to the return line but I might add one in the future if I have problems. I though e85 required all metal system, but I don't know) I wanted to do e85 but no one sell it commercially. I guess I read wrong, damn forum or damn eyes. I was under the impression that the whole feed line should be -10 but I got a good deal on 15 ft for under $50. House of boost says their aeromotive will be around $700 so that won't be an option. Actually its a good price but I already purchase my pump and filters
