Fuel delivery
HI guys,, I was experiancing hard start prob's (2001 spottrac v6) I tried everything, plugs, filters, and sensors etc. What the trouble seemed to be was the pump in the tank was allowing back pressure through its stop valve, causing fuel to back drain from the rail, The pump was delivering the pressure ok, but after switch off fuel drained away from the motor, especially when it was hot after a 20 minute stop, and starting was hard, with the odd small back fire through the air filter box, and heaps of winding over on the starter, turning the Ign' off and on did nothing to help, so I obtained an inline fuel pump, installed it between the fuel filter, and the engine USING NEW RUBBER HOSE and re routing it to the rail, leaving the origional fuel line where it was and securing it in place just in case I would have to return to using it again, I wired up the pump via a relay, switched in the Ign' bingo.....fuel to the rail, hit the starter Wow...1/2 a turn and away she went, so sweet...I did not realise the problems low fuel pressure causes, untill the motor was running as it should...... Idle, acceleration, starting, engine response, fuel saving, and probably more......The Ford remedy is replacement of the tank unit, sure that would do the trick, but here in the Philippines that unit costs P43.000.00,,, that is more than US $1000.00,, the inline pump was $20 bucks and the job took 1 hour,,has anyone else done this ??
