Default High end external fuel pump

Dropped in to seek some team expertise / experience for fuel pumps to suit the V12. I have gone all in on the car over the last 3 or is it 4 now - hell fire - I find myself seeking an in line fuel pump but I am looking for high end / reputable manufacturer, I am in too deep to cheap out.

Bosch are in the running for sure but I am also looking at Sytec, Ti and Walbro. I don't think there is much between them.

Pump list so far
  • Bosch 0580464070 - 201 ltr/h @ 3 bar
  • Ti Automotive FP606 - 186 ltr/h @ 3 bar
  • Walbro GSL391 ( I think the Ti and this pump are actually the same manufacturer / same pump which is Ti ) - 186 ltr/h @ 3 bar
  • Sytek FP603 - 186 ltr/h @ 3 bar
Anyone have any other recommendations or experience a pump in the above list.

I have run that Bosch for many, many years, and NO issues at all.

A spare in the boot, never a bad idea.

I do have a shut off valve that will be introduced so that I could swap the pump or service the filter even with a full tank. I'm actually more concerned about consistent delivery and also the ability to flow.alongside the consistency.

I think the Bosch is a go to staple for many and is a route I'm more familiar with also - the others I have no experience of.

Went with the Bosch but the 0580464008 as it has a better flow rate. As near I can tell the Jaguar part equates to the 0580464070, I include this stuff here in case anyone is looking for a pump, I have found that many 'car part' sites will list numbers as if they're the same when they absolutely are not, they may 'look' the same but they aren't. Do not be quick to accept any old pump from motor part suppliers.


The 070 based on my research is the Jaguar equivalent

008 has higher flow rates overall.

070 has similar slope but lower overall flow rate.
