hector46 Posted September 16, 2014 Share Posted September 16, 2014 Hello, This is my first post on here. I've recently bought a water craft that uses an EJ20 legacy engine, since I hope to have this craft for a while I need to get up to speed on the complete engine and fuel/ignition systems etc. Does anyone here think it is possible to convert the fuel supply system to single pipe with no return as used in more modern auto set ups? My aim is to reduce the number of pipes and connections involved in the fuel system that are in the engine bay and fit an in tank fuel pump with built in fuel regulator/sender etc. I appreciate this would not be normal practice but perhaps someone will know if this is possible. I'm still looking for the engine code on this motor, since it came from a replacement engine supplier with no vin I've been scotchbrighting around the block but no code yet. I've found the number 517639 on one flat near the edge of the block at the bellhousing end. The engine is an EG20 with red rocker tops and inlet manifold, non turbo. Thanks in advance for any help or advice on this. Steve H Quote Link to comment Share on other sites More sharing options...
Gambit Posted September 16, 2014 Share Posted September 16, 2014 Hi steve id pm tlag on here with a link probably best person to ask on here with the legacy engines. Quote Link to comment Share on other sites More sharing options...
Adam Posted September 16, 2014 Share Posted September 16, 2014 Tlag is on holiday in the USA driving route 66 at the moment so he will be no use to you whatsoever. And no, I'm not jealous, not even slightly! I'm sure in theory you could do away with the fuel return line, maybe with some sort of upgraded pressure regulator. Never done it myself though, so that is really just me thinking outloud. Sorry I can't be more helpful. Oh, and welcome to the forum. 1 Quote Link to comment Share on other sites More sharing options...
Gambit Posted September 16, 2014 Share Posted September 16, 2014 He's even posted today posh @£$$%% ;) I remember him saying he was going to do that now you have said, just didn't realize it was that soon . And I agree not something I would ever want to do ever -_- :P Quote Link to comment Share on other sites More sharing options...
hector46 Posted September 17, 2014 Author Share Posted September 17, 2014 Thanks for the replies everyone. I'll pm tlag when he gets back from the states :) . I'm going out to where the craft is tonight to look for the engine code, ECU code etc. I want to get some spare components for the engine management system once I know what I need to get.

hector46 Posted September 18, 2014 Author Share Posted September 18, 2014 I would like to carry a spare ECU with me (the RAC don't recover watercraft apparently :) ) The engine is from a 1999 Legacy ECU code 22611 AC840 8K A18-000 DJ5 Unisia JECS How easy is it to recode or reset a replacement ECU (with the same part number) to allow plug and play should the first one become faulty? Thanks Steve Quote Link to comment Share on other sites More sharing options...
Gambit Posted September 18, 2014 Share Posted September 18, 2014 I'm not sure myself I'd either PM Simon from Jolly Green Monster on here or maybe give him a ring if he's not too busy. http://www.jollygreenmonster.com/ I don't think there is anything Simon doesn't know with regards to mapping and ECU's :D Quote Link to comment Share on other sites More sharing options...
hector46 Posted September 18, 2014 Author Share Posted September 18, 2014 Thanks again, I'll give him a try. Steve 1 Quote Link to comment Share on other sites More sharing options...
