Kevin W Posted April 6, 2006 Share Posted April 6, 2006 I have a J-Spec. with the usual BPU - HKS filter, wider exhauast, etc.. I have seen quite a few threads about upgrading the fuel pump to a Walbro, but how do I know if I need it? Presumably the engine would run lean on high revs, but are there any signs to suggest I need a new pump? Has anybody experienced an improvement in their car after fitting a Walbro? I don't really want to go to the trouble of fitting a new pump unless it would make a difference.... Thanks! Link to comment Share on other sites More sharing options...
chilli Posted April 6, 2006 Share Posted April 6, 2006 I think you change it as a precaution, rather than waiting and hoping for the best, problem is signs = potential damage, you don;t want to take that risk for the sake of £100 or so... It's not hard to fit, it's not very expensive, for a BPU I'd say it's a wise safety measure, rebuilding the engine is not cheap! You could fit a wideband O2 and this would warn you of low fueling, but the walbro mod is cheaper and addresses a possible cause of it, rather than just alerting you to it, best of all, fit both Link to comment Share on other sites More sharing options...
Lucifer Posted April 6, 2006 Share Posted April 6, 2006 We have both of these at good prices, doing a group buy for the AEM wideband at the moment. Just £169 Link to comment Share on other sites More sharing options...
Stonkin Posted April 6, 2006 Share Posted April 6, 2006 Getting the car on a rolling road is also a good way to check your fueling mate Link to comment Share on other sites More sharing options...
