			Fuel Injector upgrade
		
 
			
				
					I am trying to improve my fuel economy in the P38 with a 4.6 Gems engine and have read that you can fit different fuel injectors which supposedly increase fuel economy. The article mentioned people in  Australia having great success fitting different units with four holes as opposed to the original units having only one hole. Can someone please help with this issue are there injectors to suit and where do i get them. 
 The injectors referenced were all Bosh Gen III
 
 [QUOTE][/From my research you can fit either a mid 90's Ford Mustang 5.0 "yellow"  Bosch gen III injector (part # 0280155700 or 0280155710) or a Bosch Gen  III Red Devil (part # 0280156013).  You can find both on Ebay while the  yellow ones are easily available and can be had used rebuilt and  matched for about $100/set of 8.  The Red Devils I couldnt find used and  come new for about $36 an injector or about $280 for a set. The yellow  injectors are 19lb bosch gen III, with matching impedance and  connection.  The Red Devil is a 22lb bosch gen III with matching  impedance and connection but also allows for our stock fuel rail clip to  be used to lock the injector top into the fuel rail.QUOTE]
 
 This is the reference but it is American and not sure it is suitable for my engine.

					You can use Bosch gen11 Yellow 19Lb  which have the slot for the top clip or Bosch gen111 which have the same function and 4 holes but are physically smaller  and do not have the slot for the top clip.
 
 In my case with a 14CUX rail, I added another oring above the one at the bottom to ensure the top of the injector did not pop out of the rail.
 
 BTW the gen111s will give more stable idle , but unless your old Lucas are dribbling I doubt whether you will see much better economy.  If the car has done lots of Ks you may see better economy, but usually by that stage there are lots of other wear areas eg cam, lifters.

					Hi,
 
 I must agree with Philip on this one, if your motor has high KM's on it, replacing the injectors is unlikely to have much effect sadly.
 
 About all you can do is ensure that you have;
 good plugs, properly gapped
 good air filter
 clean MAF
 clean PCV system
 
 You can also use a generic OBD reader and software to check for engine fault codes
 
 Good luck!
 Steve
