Looks like my current pump has had a heart attack on the weekend . Aeromotive 11106.

What are your experiences wth either Aeromotive A1000 or Weldon 1100A ?
Daily driven , including interstate 12 hour plus runs .
Around 670-700 HP 505ci Mopar wedge .
The 11106 has run for 6ish years . I have a -6 return , can upgrade to -8 . It's only $
Noise isn't a problem/worry .
Either pump is around $700.00 here to buy

TIA

Aeromotives are good pumps but my experience has always been that Weldon's are better. JMO

As for a #6 return, depending on your fuel flow the #6 can be a restriction in under load and can sometimes heat the fuel in hot temps and that will shorten pump life. You got six years plus on an Aeromotive which is pretty good life depending on what pressures and hours of use you are running. I agree, upgrade to a #8 return.

Weldon has always been top tier.
Put a pressure gauge on your return line some time. Think of all the fuel returning when the engine is idling or using a very small amount of fuel. I'm pretty sure your -6 is a big restriction. You want as little pressure as possible on your return line, especially if this is EFI.

thanks guys .
ordered a 1/2" fuel sender , that is my return , and will upgrade that . Oh - it is carbed 1050 dominator
Pump will probably go Weldon , is cheaper here than the A1000

Don't forget about Fuelab. I've been running a Prodigy for a decade ~500hp on E85 so uses about 700hp worth of fuel. Pump is sized for 1000hp I think.

just a feed back .
Found I didn't need a pump , other issues . Nut behind the wheel .

Did spend up going -8 return . Dropped just over 1 1/2psi on the gauge at regulator
thanks again for input/help
Will be testing Saturday , and have some 100/102 & 103 main jets to try . Should be quite cool - teens Celcius with a dry southerly breeze
