seaswood Posted November 14, 2018 Share Posted November 14, 2018 (edited) Truck A is a xmod 90 2.5 na diesel (87) fitted with a Sedimenter along with the fuel filter, this works quite well seems. truck B is a 110 PU with a 200tdi (84) only a fuel filter , a project. the 90 has same size fuel lines to & from filters fuel tank., the 110 has smaller return line to fuel tank,. Is this normal for the two engines or is spec different for xmod? planning to add a Sedimenter to 110 & was wondering about the difference 2.5na & 200tdi engine parameters.

Eightpot Posted November 14, 2018 Share Posted November 14, 2018 Ex MoD fuel system is same as normal. Could be that the 110 has been converted from petrol. If the 110 has been 'correctly' converted and uses a tdi fuel filter, it has a sediment/water valve on the bottom anyway. Quote Link to comment Share on other sites More sharing options...
seaswood Posted November 14, 2018 Author Share Posted November 14, 2018 So the valve on the bottom can be used to drop water periodically, I am assuming it was converted thnx. Quote Link to comment Share on other sites More sharing options...
western Posted November 14, 2018 Share Posted November 14, 2018 Yes, just slacken it off let any water drain out & retighten Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 14, 2018 Share Posted November 14, 2018 84 is way too early for a 200TDi so must be a conversion of some sort. Quote Link to comment Share on other sites More sharing options...
seaswood Posted November 14, 2018 Author Share Posted November 14, 2018 I removed a gas filter from the frame when I got it. so should the return lines be same diameter as in lines for 200 tdi? the 200 tdi does not have return lines from injectors? Is this normal? the 2.5 na uses three of the fittings on fuel filter plus uses the top fitting both ways for return. whilst the 200 tdi uses one fitting on filter & one side of top fitting, a simple in & out which seems simple maybe limited system.

western Posted November 14, 2018 Share Posted November 14, 2018 200tdi fuel filter connection diagram below, taken from my own 110, yes 200tdi has spill pipes from injectors back to the FIP, Quote Link to comment Share on other sites More sharing options...
Ex Member Posted November 14, 2018 Share Posted November 14, 2018 You do NOT want the return to go to the filter like the 2.5NA. That was a really bad design and made purging air from the system very hard. You DO want a sedimenter. Without one, the check valve in the lift pump will catch dirt and stop working.

seaswood Posted November 14, 2018 Author Share Posted November 14, 2018 Okay so seems to be same as western diagram shows. i found return lines to injector pump yes different from 2.5 na plumbing.of which caught my attention. better to know why. seems I could install Sedimenter inline between tank & lift pump. up on four chaulks, one differential in Salt lake, new rebuilt tranny in box no rush tho here.

roamingyak Posted November 15, 2018 Share Posted November 15, 2018 Note: The sedimenter on mine (exMOD 2.5n/a, now a 200TDI) next to the fuel tank will clog up with black mould/gel over a long period, so worth pulling it apart every few 5 years and cleaning it out etc. I've seen some that were completely full and blocking the diesel flow, that takes many years usually...

You should also run a strong biocide through the system to kill off the existing fungus. Quote Link to comment Share on other sites More sharing options...
seaswood Posted November 15, 2018 Author Share Posted November 15, 2018 Five years I just did annual fuel filters including Sedimenter which takes 15 minutes, the fuel filter little longer to avoid spills. the lift pump still works fine bleeding system or I am just lucky there, in xmod 90. LR supplier suggested I use stainless for the fuel lines adding Sedimenter in rear of 110 PU. is there one system better than other, size of fittings?

Posted on here and was suggested I tried Jeyes fluid which seems to work, small amount in the fuel tank on each filling. I noticed there are numerous commercial fuel biocides in motor shops.
