How Fast Should 300SDL be?
Mine's pretty slow.... Got the flex pipe replaced and made a little difference but how fast should it be?
New fuel filter, new air filter... What else causes sluggish acceleration? |

Time a few 0-60 runs and report back. You should be in the 10-12 second range.

Check that all the small "vacuum" lines on the drivers side of the engine aren't plugged with soot. Mainly the one going from the intake to the lill valve unit.

10.5 seconds is very fast.
12 seconds is typical. |

A loss that significant sounds like fuel starvation. Change both fuel filters (the in-line filter and the spin-on cartridge) and report back.
EDIT: just saw that you already have a new fuel filter. Did you change both filters or just one? Make sure they're both clean. Also, take an air compressor, take off the fuel return line to the tank, and blow some air backwards through that line to blow any grit or algae off the strainer in the bottom of the tank temporarily, just to experiment. |

I did the one that is right near the engine itself... Wheres the other filter?
How do you do all this stuff to the tank, i have access to my fathers garage and all the tools in the world, but i am no mechanic. |

One of them is clear plastic, the other is metal like a gasoline engine's spin-on oil filter. The plastic one is in-line with the fuel supply line, which comes through the firewall on the injector pump side of the engine. The metal one is up in front of the power steering pump reservoir. You remove the bolt from the top of it, maybe unclamp a bracket to get it out of the way, and then replace that filter as well. Fill it with clean diesel or diesel purge stuff or whatever you want to use that will burn as fuel so that the re-priming process doesn't take as long. Re-priming in your car consists of leaning on the starter for up to 60 seconds until she fires up and keeps running. The return line goes right next to the supply line back through the firewall, both lines attach to metal pipe things coming up into the engine compartment with screw-type hose clamps. Just unclamp the one going back to the tank (the one with no filters in line with it) and blow down the piece that goes back through the firewall with compressed air to just experiment with clearing the tank strainer from the front, so to speak. It's a temporary cure if that is the problem. Maybe take the fuel cap off the back before you blow air through from the front just so you don't pressurize things and create a fuel jet somewhere if your vents happen to be plugged . |

I figured out what filter needs to be replaced its the straight filter, so just put air into the return fuel line... ok will try, what about clearing the build up will i need to remove the tank?

Worst case scenario, the strainer drops out the bottom of the tank and you'll have to catch the remaining fuel somehow. |
