After fuel pump recall/repair gas mileage decreased by more than 30%, how/why?
What is your question?
Dealership is attempting to attribute this on the type/brand of gasoline, but that hasn't changed in the 5+ years I've owned the van. The wife is a creature of habit and nearly always buys gas and washes car at the same service station. Dealer also trying to point to my spouse... that her driving habits have changed? Don't tell her I said so, but she's actually a good driver. Smooth on gas and the brake...Not a speed demon nor a grandma behind the wheel. She's the only driver of this car. This MPG decline coincides perfectly with the recall repair. What do I say to get the dealership to take a thorough look at their recall work to find the issue?

That used to be true , but we are both old geezers in this trade.......return-less pump modules like what Honda(and most others I think) have now , leave lots of in tank problems because of all the parts crammed into one unit that 30 years ago were spread out from the back to front of the vehicle! On this recall we lust change the filter housing , swapping the actual pump and regulator and sending unit. SEVERAL O-rings that can be screwed up and cause problems! The most common issue I've heard of so far (and seen maybe twice at where I work--out of hundreds done there!) is the fuel level sending unit being messed up on install. Hopefully we'll see a reply.....never know anymore....HI Bruce.
Na, they pretty much all like that anymore!.. All in one module... Have had folks think that more pump pressure caused a drop in mpg... but you know the drill ... Scanner... Fuel trim... O2 and pressure readings should be a dead giveaway... One would think that would have been checked with a complaint... Maybe not!... Fuel mileage 'facts' and actual figures are most elusive it seems anymore!!!.... Old geezers, speak for yourself!! What's happening...
