I am sure that most of you have noticed the discrepency in the length of the design lll's by 1/4 inch or so. If you follow these instructions the installation problem will be solved.. guaranteed!
We have sold HUNDREDS of the design lll fuelinjectors. First of all YOU DO NOT NEED TO GRIND DOWN ANYTHING!!. It is a known fact that these injectors are a little shorter than stock. All you need to do is install a second o-rind on the bottom, THIS WILL TAKE CARE OF THE 1/4 inch in the length!! very simple, you install into the intake manifold first!! Then the fuel rail AND YOUR PROBLEM WILL BE SOLVED! We send out our design lll's with written installation instructions, a picture of where the 2nd oring should go, and we also send the additional orings that you need. Just follow these simple instructions and the problem with the injectors will be solved. GUARANTEED!! A copy of these instructions are included with every set of Design lll's that we sell.
I dont understand your question but this fitment issue has been posted many many times... you will have all the information you need to install them if you search the forums.

I really dont think he has a question. Looks more like he is trying to pass on some information than ask a question to me.

I did not have a question, you are absolutely correct. Just wanted to pass on some info., read a post the other day and everyone was talking about grinding and milling to make the injectors fit, again, totally unnecessary. I was starting to write the post and hit the submit button before I was done LOL
Anyway hope this solves the problem for alot of people.
That is what I thought you were going for. Thanks for the info. These are the LS1 style injectors right? I am thinking I might go with those as well if I have to buy a set here soon.
The spray pattern on these is real nice, come out more as a mist( very atomozied) like the multecs but without the problems of exposed coils and inability to handle higher fuel pressures. I know if I buy new these will be my 1st choice.
The design III`s are the same as the ls1 injectors right?Someones giving me a set of the ls1 26#ers,I believe they are,with only 40,000 miles on them.Are these the ones I will have to use 2 o rings?From my searches thats what I`ve come up with just not in so many words
LOL
