Right now i have dual 255's running gas and im about to go e-85...what other dual pumps can i run?

ive looked at the aeromotives, and the new 400's and everything i find is in tank.

I'm surprised there isn't more interest in this, but I see
very few external fuel pumps that can run at 4 bar head.
Aeromotive makes one but it's like $399 and reputed to
be super noisy.

If you could stand to run 3 bar fuel pressure then you
could parallel as many Ford pumps as you liked... but then
you'd need even more injector.

If twin pumps can't supply your fuel, you might need more
attention to the forward plumbing (diameter). Especially
if your regulation is still back by the tank, how do you
know the relative contributions to overall pressure fade?

i run base 43 psi, have dual 255's which have been told many times that is good to around 800hp

im thinking about going e85 and would like to keep a pump like the walbro's but ill just do one of the magnafuel pumps for my 2nd pump if theres no other external pumps like the 340's or higher

A buddy of mine is using an external 340 on his mercedes. I use the magnafuel 4303 and it's been working fine.

did you end up going to e85? if so what did you do with your old dual pump set up?

Sounds like similiar situation, sorry for slight hijack.
I was about to post but done a search first....

I am running a TT with E85 should make 850rwhp.

I have -
fuel cell
then XXX
into 4L surge tank
then 4303 Magnafuel pump to 1/2" line to indy whites.

The XXX is my missing pump. As stated by all everythings in-tank or $300+ for an inline.

From cell to surge tanks what size pump will do and hold enough fuel for this combo.

Then what pump would be recommended, must be E85.

I'm sure there are plenty using the Bosch 044 with E85 and no problems. I know a good few people in the UK have done.

4 bar is nothing to an 044.

Are you saying a single 044 will handles E85 volume with the extra fuel required with
E85.
Also would 1 044 handle the volume required to the surge/swirl po?

Well you haven't stated your flow requirements, so I've no idea if a single pump will do you. And I've no idea of your main tank design to determine whether an external swirl tank is required

i made 1000whp with a sumped tank, two bosch 044's and id 2000's. they make some nice pump hangers for twin 044's too.
