i am loooking to upgrade my fuel system i i dont really understand the whole in tank fuel pump and external with a custom sump idea so i was wondering if its possible to have a fuel cell and run a aeromotive a1000 pump if thats enough to push say 450-500hp and what size fuel lines from the pump to the rail and return do i have to upgrade to is 3/8 big enough?

 

i guess i really want to know is will just the aeromotive be enough for 450-500hp and like 15-20psi of boost

 

Just run dual walboro's or supra tt pumps. CJ-motorsports has a very nice setup that is a drop in replacement.

the a1000 is plenty of pump for that. I am running one.

 

And i run the duels there is quite a few options.

 

LUPE ran a A1000 and made 603whp on it. 3/8 fuel line is plenty of fuel. It equates to 6an. Run a 6an feed and return and you'll be fine.

Dual intake assemblies are also just as good. Dual Denso's and dual Wabro's will get you above 600whp and depending on the mounting are virtually silent. Avoiding "T" fittings will also maximize flow capability.

Running an external pump requires a sump pan as you cannot fit an external into a fuel tank. The use of the sump pan is to create the lowest point possible and while in the process of adding it you can modify the baffling.

 

Isn't a1000 now being put intank and runs quiter and cooler?

 

no its the eliminator pump from AeroMotive which Is one BAD *** pump
which is on my shopping list...I currently have duel walbro's but for 4 Bar its not enough

i just finished my fuel pump set up.

 

i was gonna go duel pumps and run 1 to each rail but opped not to due to the risk of having to worry about a failure there is twice the failure rate w/ two pumps. so i went a1000 will be running -8 to the rail and -6 out. should be plenty of fuel

This is an awesome example of what can be done using the CJM twin pump bracket. Very nice work, very very nice!!!

 

best way to go is a in line fuel pump
