Good catch! I assumed they would be the same as the 044. Guess we are stuck with the "Y" blocks.

Any thoughts on compact, but not restrictive pre-pump filters.

Why are these blocks designed to use the check valves? Are they actually using the check valve or just because that's how the 044s are delivered?
I think they were just all designed for the 044.

Here's a US seller.

No idea on compact pre filter's. I used a surge tank with no filter on the Aem 380. It's fed by the OEM intank sock pump.

Let us know what you come up with!

This is how I plan on doing it, minus the surge tank and with AEM 380s. The Y setup will be more compact with AEMs since the check valves are built into the 8AN fitting.

Kinda of a bad pic, by here's how I did mine. This is with 2 mock up 044s. It's just a log with 1/2" npt ports. A 12an feed into the side, the two pumps each have a 8an coming off to a wye which attaches to a 10an all the way up. I run two AEM 380s on E85. No issues all last summer. The fittings on the AEMs are different threads than on the 044s.

Then run one of these $20 twin pump adaptors.

For $22 shipped you can buy 2 of the bosch clones and get 2 pumps for $14 and rob the check valves off them.

Or these that claim 300lph for a bit more.

044 check valve will not screw into the AEM pump.

AEM uses -6 outlet on the pressure side and -10 on the intake side.

Bosch 044 uses M12 on the pressure and M18 on the inlet.

If you really must retain the check valves for a pair of 044's for whatever reason, then there are already options out there

It isnt a 3 pump, it's 2 pumps feeding into a filter. A shitty filter that will flow **** all too.

But yes, whilst compact, still **** for flow. That said, if the orifices are big enough it probably wont impact overall flow too much anyway

Anything against all the usual filters ? Holley, Earls, Aeromotive, etc etc etc ?

Some people obsess about check valves. They are not needed. If you want an 044 to flow more...throw away the check valve, the same will apply to the AEM.
It does mention the difference in their instructions, but dont have them to hand.

Obviously if you want to stage the pumps then you would need check valves somewhere though

I was just referring to the tri pump picture. Not that it was 3 pumps. I agree though.

I have one and a 255 just going into a y. The check valve for the 380 is fn tiny inside, I just used an open fitting instead. I ran out of pump with dual 255s but I'm fine with the one 380 added
