New Fuel Pumps, New To Me Anyway!

[MagicMikeZ32]

I'm using SSR to control 2 x 485 pumps via link G4+. Working great.

What is the actual SSR you are using?

With the heat sink

the switching delay on those is terrible (500usec) but i guess you dont really need a linear PWM duty to output response for pumps.

if you want to run at a reasonable frequency (5-20khz) you want to use one of these

Anyone seen or used the new(ish) AEM 400lph fuel pumps ?

direct replacement for Bosch 044

2 types, one with AN fittings and one with metric threads identical to the 044 pump

flows more everywhere and is compatible with e85/e90

Are these like the proflow ones off eBay?

[SiR_RB]

Can’t say 

I just got that info from aem as they had proper flow tests done unlike the eBay copys

im guessing the proflow ones etc are like the Bosch 044 copys 

[cul8er]

I’m looking for genuine Bosch 044 x2 but don’t trust any one selling as there’s way to many copies now

Hit up aftermarket industries in Sydney 

they have the real deal

Unless your running more that 30 psi boost you will never have more than 70psi fuel pressure so the 460 wins hands down

[MagicMikeZ32]

Depending on your base... But the 274 handles higher pressure anyway. I agree regardless, 450/460/485s are proven. 

[MagicMikeZ32]

Should specify that the 274 is the last 3 digits in the part number. The one from the graph above is 267.
