michael Posted August 21, 2007 Share Posted August 21, 2007 195130-1020 on the one I have here. Quote Link to comment Share on other sites More sharing options...
hadyn Posted August 21, 2007 Author Share Posted August 21, 2007 Is it the US spec pump?? Or is the above number specific only to denso, not toyotas part number catalogue? http://www.autopartsworld.com/1997_toyota_supra-turbo_fuel-pump_parts.html Or is it the denso equivalent of a walbro uprated pump?

michael Posted August 21, 2007 Share Posted August 21, 2007 The Toyota one is a Denso part as far as I'm aware, that's the Denso number on the pump, the US one is the same as the UK. Toyota will have their own part number of course... so I guess I'm not being very helpful Quote Link to comment Share on other sites More sharing options...
hadyn Posted August 21, 2007 Author Share Posted August 21, 2007 Hmmmmmm very strange. Must be an uprated pump? Quote Link to comment Share on other sites More sharing options...
michael Posted August 21, 2007 Share Posted August 21, 2007 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. Quote Link to comment Share on other sites More sharing options...

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.

hadyn Posted August 22, 2007 Author Share Posted August 22, 2007 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: http://mkivsupra.net/vbb/showthread.php?t=54498&highlight=rx7+fuel+pump 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? Quote Link to comment Share on other sites More sharing options...
michael Posted August 22, 2007 Share Posted August 22, 2007 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: http://www.stealth316.com/2-fuelpumpguide.htm 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: http://www.roadraceengineering.com/fuelpumptechtip.htm Quote Link to comment Share on other sites More sharing options...
hadyn Posted August 22, 2007 Author Share Posted August 22, 2007 Thats not much better than a j-spec pump is it? Quote Link to comment Share on other sites More sharing options...

bodilx6 Posted August 23, 2007 Share Posted August 23, 2007 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 Quote Link to comment Share on other sites More sharing options...

The UK pump flows a lot more than the J-spec pump. Quote Link to comment Share on other sites More sharing options...

hadyn Posted August 23, 2007 Author Share Posted August 23, 2007 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? Quote Link to comment Share on other sites More sharing options...

bodilx6 Posted August 24, 2007 Share Posted August 24, 2007 yeah, is there *ANY* reason to go for that compared to the walbro? more reliable, flow or ? Quote Link to comment Share on other sites More sharing options...
michael Posted August 24, 2007 Share Posted August 24, 2007 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.

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. Quote Link to comment Share on other sites More sharing options...
