+1 someone post some pics of an fc if you got em. I've always steared clear of external pumps because I'm not sure how to attach the stainless part to the tank.

 

A nice belt driven pump.

 

Wow! Now that is just freakin insane! Wonder where you get that kit from?

edit: nevermind just went to that website.

 

yeah that aeromotive mechanical pump is a beast! good for your daily driven 2500 hp

 

how did you modify the baffling inside? what would be nice about having the sump inside is that the fuel could slosh as much as it wanted. being in that lower area would help prevent from sucking in air!

 

another question... since i have to run a 10an from the sump box to the pump should i run forward with 10an or match it right to what kg parts uses? pretty much should i step it down at the pump or at the engine bay?

 

Do it at the engine bay.

 

-10 all the way from the tank to the engine bay?

 

That is correct.

 

ooh ****. I got -10 from the fuel tank to the pump then -8 from the pump to the engine bay. then -6 from the Y splitter to the FPR then back to the tank. Do I need to change it out? Or should I be good? none of it is installed its just in my room collecting dust until I get around to putting it on. But also. Any suggestions on where to mount the pump? and how to feed the pump with my in tank walbro? I have a SX performance external fuel pump.

 

Nice also as silver94r2 stated he did... should i weld any baffles inside of the sump tank while im at it? or being that low should be good enough since its the lowest point...? lol one more the sump tanks that you buy have 3/8 or 1/2 bung selection. the 10an would go for the 1/2in correct? thanks in advance!!!

 

check this out
I'm trying to design a fuel system for my future needs
can't run a surge tank cause of NHRA Import class rules

The only other option is to maybe copy a local nizzan 240sx racer
that uses a single walbro that feeds a custom fitting out of that feeting is 6 feet of -16AN fuel hose coiled up, then a weldon fuel pump gets if fuel from there -10 feed and the return is sent back into the "custom" fitting...no surge/swirl pot system and legal

second choise
is a sumped tank most people use the chassis engineering sump
which when used with a return can cause turbulance in the fuel supply and causes issues

Check out this sump

hold 3.5 gallons and is baffled
more pricey but wayyyyyyyyyyyyyy better design

anyone think i should not use the aeromotive fuel pump computer?

 

Eh I'm doing a surge setup.

SupraTT in-tank running to a surge tank. Surge tank running to an A1000 pump feeding the rails.

It makes it quite easy cause the supra pump will keep the surge tank full at all times... and while hard turning I dont have to worry about the pump dry running due to the sloshing around of the fuel in the main tank. I suppose if your tank is designed correctly you wouldn't have to worry about that either.

Just my $.02

 

I use to have an Aeromotive external fuel pump and it was too loud. I replaced it with two Walbro intank fuel pumps and they are very quiet. No problems so far with the setup and combined they can flow more fuel than the Aeromotive.

 

I know some Supras use 3 intank walbros and make over 1000HP with it (6 160ibs injectors)
don't know if we can fit it tho with out cutting and fabricating a custom fuel pump assembly

 

Three Walbros are overkill. Two can flow more than 700lbs/hr. That is more than enough for four 1600cc injectors. That is what I have right now.

 

i just dont like thinking about losing one of those pumps... kaboom!

my buddy with an rb26 is doing the surge tank method... he thinks hes going to be big with drifting. yet i dont know why you would do the rb26 for drifting.... thats like overkill in itself.

 

Not on a rotary application. I have maxed dual supra and walbros at 600rwhp using 2X750cc/2X1600cc injectors.
They make the power on the dyno but the minute you put the real test to them under actual load on the street fuel pressure drop off happens in 3rd gear at that power level.
Using 3 in-tank pumps is going to tax the Mazda electrical system.
Your best bet for extreme high power and high G-loads application would be one or two external pumps fed from a surge tank or a sumped factory tank.

 

^ crispeed you obviously know what your doing... what do you recommend i use for a sump system on my fd? should i run a surge tank like all the drifters do or is a sump bin fine? its a street car but will be dragging at the track. also can you recommend a relay for my a1000 pump?

 

I would get the controller that has a built in relay
yes its more money but it can make the a1000 street friendly and extend its life

 

For anyone interested, I'm no longer going ***** to the wall! I'm selling my Aeromotive eliminator pump, both Aeromotive filters, and the Competition Engineering fuel sump pan! https://www.rx7club.com/showthread.php?t=705767
