Hdi Lift Pump Upgrade (Pics/Tips inside)
#21
That part about the reg was in response to Chris, bud.

Absolutely, but how do you know just keeping the filter housing topped up is enough? Have you flow-tested a filter housing with filter to see just when it becomes a restriction? Not having a go, just pointing out that until we come across better information or somebody with the means tests these items, we can't know.

The ecu won't wait for the system to run dry before it cuts out, it just has to see a significant difference between requested and actual iq - as such just keeping the fuel filter wet may not be enough, the system may require a certain pressure pre-hp pump. By the same token, a constant supply might be all that's required; although that seems unlikely, else why would they put a 3.2bar pump in as standard when there are much cheaper units that run at lower pressure... But, we can't know for sure before it's all tested.

Indeed, exactly as i've said before. Obviously it's not exactly a proper solution, but if there's no plan to go beyond stage 2 then it's all that's required.

Even the walbro pumps are cheaper than the standard items, iirc peugeot charge about £90 for a genuine lift pump. I think it should be a worthwhile mod, but again, until it's tested properly we can't know whether it's an improvement or not. Wink
