8.3 Cummins - turning up the injection pump - transit360 - 11-09-2005 07:49 Hi guys, Does anyone here have any experience with the 8.3 Cummins? To me, it looks identical to the 5.9 except bigger of course. I'm wanting to turn up my injection pump to get a little extra juice and was wondering is someone could pinpoint where and how to turn it up. I have two matching pusher buses right now and one of them runs like a scalded dog and the other one's a slug in comparison. Both get the same fuel mileage for the most part (around 7-8mpg). Both have new fuel and air filters and clean diesel, so I'm down to try and juice up the pump. The one that has more power also smokes a little more, with a more detectable smell of diesel than the other from the extra fuel, so I'm thinking that someone has already turned up the pump on the faster bus. All specs as far as temp, oil press, rear axle, etc are the same, which is why I want to try the injection pump next. Any suggestions? I'm sure it's simple but I always like to ask anyone's experience.

There are folks on BMC site running the Banks kit - not sure if anyone turned up the pump. http://autos.groups.yahoo.com/group/BlueBirdBMCowners http://autos.groups.yahoo.com/group/Diesel-RVs/?yguid=154352493 Dan 94 BB BMC 37' --- In WanderlodgeForum@yahoogroups.com, "transit360" > > Hi guys, > > Does anyone here have any experience with the 8.3 Cummins?

When I have a prob in my 5.9 I drop 2 quarts ATF in 30 gal. of fuel and put 50/50 mix of ATF /Fuel in a new fuel filter. Maybe the diesel smell and smoke is normal?
