bodilx6 Posted August 29, 2012 Share Posted August 29, 2012 I'm running j-spec BPU with a fuel pump of unknown brand. I'm guessing it is a Walbro, as the guy who installed it 6 years ago, when I knew nothing, called it "the internet pump" and talked about me having enough fuel for much more hp's that BPU will ever push. It is aly a bit noisy once in a while, with whineing noise, specifically after quick motorway driving. I know that to swap some fuel pumps in, need some relays installed, but I'm not sure when that is. Car was 100% stock before. Now I got a hold of a Denso pump, part no.: 195130-1020 (see pics) Now, the question is, will I be able to switch the two pumps without having to modify anything? When I get down there, what should I look for, if something has been modified to fit the first pump? Also, I'm guessing that the Denso pump easily will flow enough for BPU, so I won't have to worry with running lean or anything (I have uninstalled my wideband sensor)? Is the Denso pump just as trustworthy and high quality as the OEM pump or would it be more comparable to the Walbro and there by not making any sense replacing? (the guy that traded it to me told me it was an OEM pump...) Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 29, 2012 Share Posted August 29, 2012 That looks like a UK spec pump. It should go straight in, although there should be a connector on it rather than just two terminals. You might need to modify the wiring to end in terminal connectors rather than the stock plug. It should fit the pump cage okay though. Question is, why are you putting it in, has the walbro failed?

Nic Posted August 29, 2012 Share Posted August 29, 2012 If you look up the part number on Google it seems to be a 290L/hr UK/US spec pump, the J-spec and UK spec pump/hangers are a different fit, it can be made to fit the J-spec hanger but you'll need to secure it in place with a large jubilee clip.

bodilx6 Posted August 29, 2012 Author Share Posted August 29, 2012 No, the walbro hasn't failed. I just had the chance to trade for it and thereby get a better pump that doesn't make noise and hopefully is the better choice. Quote Link to comment Share on other sites More sharing options...
V8KILR Posted August 30, 2012 Share Posted August 30, 2012 Denso are OEM quality parts and should be extremely reliable and quiet. Quote Link to comment Share on other sites More sharing options...
