Some time ago my el-cheapo fuel pump started to make a very unnerving noise when it was getting warm… And yes, fuel tanks are sparkly clean and I have filters before the pump, so dirt/rust is not an issue.
It’s the second pump going bad in a very short time, so I wanted something better.
Not many options though:
- Walbro (@gregma recently installed one in his XJS),
- Various el-cheapo versions and Bosch knock offs…
I really wanted to get a “turbine” style pump, as they are generally much quieter and, because there are no friction parts inside, theoretically last longer.
I also wanted something that would be E10 compatible.
On my research I stumbled on this article: https://www.boschautoparts.com/documents/101512/0/0/33b29fbb-6d41-4a1e-9424-7e25e8773060
Apparently after a certain date, IIRC around 2010 - 2015, they replaced all the old style fuel pumps with new turbine style pumps, but the exterior shell and shape remained identical.
And they are all compatible with up to 20% Ethanol fuels.
For the XJ6, XJ12 and XJS Bosch gives the same two different part numbers (for a unknown reason, and just for the sake of confusion, the US site uses 5 digit part numbers)
0580 464 008 (69536) and
0580 464 070 (69414)
I have no idea what’s the difference between the two pumps, their specs are exactly the same.
I found one on e-bay, a recent 0580 464 070 pump, box opened but never used, so I bought it.
New style bue box and with an authenticity sticker and number that you can check it on the Bosch website.
The pump itself is wrapped with a plastic film on which 0580 464 070 and “Made in the Czech Republic” are stamped. Neither the box nor the leaflet included have any mention of specs or pump type.
The electrical connections are screw type and not spades.
I installed the pump and I was very happily surprised to find that it’s totally quiet and absolutely vibration free !!
From inside the cabin it’s virtually inaudible.
And most important of all, the V12 works just fine.
