I have a fuelling issue (I think).
Engine is a 2.8 AAH V6, fuel regulator is set at 4 bar. However I have been running the original Bosch 2.1 DJ fuel pump which ran at 3 ish bar when new. So lack of pressure may be cause of one of my issues but I am confused by black smoke also being present, which I associate with over fuelling.
I am thinking of replacing the fuel pump. Bare in mind the 4 bar regulator should I be looking for a 4+ 5+ 6+ bar pressure inline pump to replace the one I have. What is the consensus on pump pressure. |

sounds like the pumps running dry on occasions? fuel starvation. you got 2.1 tank also? how much fuel is in the tank when this happened? had a look inside tank lately? might just be bits floating around and blocking outlets?

It had a standard 2.1 DJ set up. I have not had the tank off, so a job to do in the rainy season.
Would the issue of fuel starvation generate black smoke tho? This can happen in a full tank. Edited by Surfrider - 24 Aug 16 at 07:59 |

I happen to have a brand new old stock Bosch fuel pump for sale, it's very similar to the original pattern, just a bit larger and better throughput/pressure.
The part number is 0 580 254 957. I have a note that the specs are 5bar, 148l/hr, but best check on that yourself. I need to ask £70 posted for this. PM if interested. Edited by syncroandy - 24 Aug 16 at 09:05 |
