Seen that myself. Given no other pump exists that can match an 044 out of the dozens of pumps that are available these days....it's really hard to imagine how they can do it with a £40 pump.

the 044 really is an outstanding pump...more so considering it hasnt really changed for 20 odd years or more ! IMO, nothing matches it.

Of course the next question is...how much fuel flow/pressure do you actually need ?
