Denso UK Spec Fuel Pump Part Number

An old thread here suggests that Toyota use 23221-46110 for the 195130-1020.

 

That's 3 year-old info though so they might have changed the part # since then.

 

Toyota part number is indeed 23221-46110, if you need a source for one Hadyn give me a shout.

OK the part number on the pump itself is 195130-0782 - I believe this for a stock RX7 pump which pushes 255lph compared to the jspec pumps 195lph according to this post:

Do you think I would be able to fit this denso pump into a j-spec supra??? Has anyone heard of fitting rx7 pumps into supras before?

Yeah that's an RX7 pump, I'm not sure about the flow statement though, this comparison site seems to suggest it flows a fair bit lower than the OEM UK/US pump:

Quite an interesting site but Stealth specific and the tests are carried out at varying voltages but the following site gives figures at 12v and suggests the Mazda one is 210 lph @ 12v:

Toyota has told me that the part no is exactly the same for the EUspec and the Jspec pump??

wouln't that mean that they are the same? why are people then always going on about needing a walbro (or other) to go BPU when the EUspec is capable of 500+ hp's

 

Toyota are talking out of their bottom, they are definitely different. The UK pump flows a lot more than the J-spec pump.

yeah, is there *ANY* reason to go for that compared to the walbro? more reliable, flow or ?

 

Quieter, flows more and is proven to last a long, long time - I'm not sure if anyone has had a Walbro running for 13 years with no sign of problems but there are a lot of UK and US people still on their original pumps, some at BPU+++++...

 

It's not hugely quieter (I don't recall too many complaints about the Walbro being noisy anyway), it doesn't flow a massive amount more... it's better but it's also more expensive, the Walbro will get the job done, the OEM gets it done and has more to give... sort of thing.

How much is a denso UK spec pump from toyota etc then?

 

Also, is it plug and play? E.g. will it just drop into a j-spec cradle and wire up without any splicing etc?

 

I can supply the UK fuel pump for £160 inc postage

 

They are a slightly different fit to the J-spec pump on the hanger, but can be made to fit.

 

The UK pump flows more than the Walbro, the Walbro pumps can be quite noisy, where as the UK spec is a lot quieter.
