Fueling issues 4g52 swapped MD l200
Posted: Wed Dec 21, 2016 9:51 pm
G'day all. I have just completed a 4g52 engine swap into an old nugget MD L200 which had a toasted g63. However, I have run into issues with fuel supply that are really starting to annoy me.
The problem- I cannot for the life of me get fuel flowing from the tank and the car will not run.
Everything works perfectly well off am auxiliary tank. However, plugging the main fuel line back to the metal fuel line on the chassis rail and the car will empty the bowl and promptly die. Fuel just does not want to go from the tank to the carb.
I have tried filling the bowl manually, starting and revving trying to get flow, no dice.
I have blown compressed air through the tank forcing fuel through the pump and to the carb, again it runs till the bowl empties.
I have blown air through all the lines, there are no blockages.
Fuel pours from the tank when I take the main fuel line off, so the there isn't a blockage in the tank.
The only things I can think of are:
Weak fuel pump, can pump small distance from auxiliary tank but not several metres to main tank.
Maybe something to do with the vapor system on top of the tank, a blockage etc not sure.
Apart from that it has me stumped! Feel free to through some 2 cents at me or help! Cheers.
