Ford Injectors?

[hin532]

I am getting ready to do a plenum pull and I want to make sure I have all parts needed. The previous owner had replaced the injectors a few years before me purchasing the car so I was not considering replacing them until looking at them closer. The part number I can make out is 0280150943 which a google search shows them to be Ford injectors.

Does anyone have any experience with these injectors?IMG_3409.jpg

I have put ford injectors in all sorts of vehicles over the years. Pretty much all my land rovers have ford injectors. Nothing wrong with them. Would they be my pic for the LT5...no. The only advantage is cost. These appear to be slightly lower flow than stock.

I have a set of those as well. I have seen them referred to as yellow tops from Z owners when talking replacement options. I installed a set on mine and they have worked well for over a year now no issues. South Bay Fuel Injectors is the site I found mine on. I believe John on FIC used to stock them but no longer does.

Truth is there are many parts common when the actual supplier is a tier 1 or tier 2 automotive supplier. IIRC Bosch was making injectors for Ford SVO back then and they were compatible in multiple applications. Built LT1 motors typically used 36# SVO injectors for example. Always do tuning after injectors change.

Note that original "fat body" EV1 type injectors are very hard to find these days. Everything switched to the "pencil" thin body style in mid-90's. Those will work too but again, you must tune.

The Accels many people use, including me, are for 5.0 Mustangs.

Bosch rates those injectors at 215 cc/min at 3 bar.

I really like the Bosch design 3 injectors, all the injector characterization data is published. But I haven?t tried them with early injector housings where the primary seal is up in the housing. It might work, but it might not.

Sorry I wrote the post half asleep last night while wondering if I needed to replace my injectors and didn?t fully explain what I was trying to accomplish. Basically what I was trying to find out was if the Ford injectors had the same issues with ethanol failure as the factory injectors.

After digging thru the forum today I think I found my answer. There was a post from 2014 that Jon with FIC put up explaining their stainless steel injectors and how they were no longer carrying the Bosch yellow top injectors due to failures similar to the stock injector on the 90 to 92 cars. This makes sense to me now because my car seems to run rough at idle once it has warmed up and is one of the reasons I wanted to pull the plenum in the first place.

So I know now that I want to replace the injectors for sure. I was looking at the FIC injectors. Do registry members get a discount on FIC injectors?

Just to be clear, these injectors were used up into the early 2000s on Ford modular motors (4.6, 5.4, etc) and are absolutely ethanol compatible. Bosch "yellow top" is a misnomer as they made dozens of part numbers with yellow tops.

I understand what they are and the blanket term for yellow tops. While the injectors would be ethanol compatible in the below thread Jon outlines that he was seeing failures from these injectors and stopped selling them. This is the information that I was looking to find out because my car sometimes exhibits symptoms of a failing injector.

Which is fine. But when he says "similar to stock injectors" that is misleading.

The failure rate among any remanufactured injector is relatively high. I was just clarifying that the failure of those bosch injectors is not due to ethanol. The symptoms of fuel injector failures in general are "similar." Fuel injector failures typically fall into only three categories: too much fuel, too little fuel, poor pattern/atomization.
