Hi all,
I am new to the third gen....just recently acquired an 89 formula, with the lb9 tpi engine.

I noticed a fuel leak at the fuel rail cross over tube....and as I have it all torn apart now...to address that.

I noticed that I have two different types of injectors.

It has 4 5156. 5235186.....Internet searches lead to believe these are for a v6 model

Then the other set is 1237 17102119.....the search here says that is old part number...but the correct injector.

So to the real question....are those other injectors going to cause a problem?

Thanks!

You can definitely run injectors that have 2 different part numbers, however they need to have the same flow rate and the same spray pattern. There are many injectors that have a different color and part number yet they flow the same. IMO you should just replace all of them.

 

While you have it apart, you may as well replace all of them.
Once upon a time it was ridiculously expensive to replace injectors.
Now that we have Southbay providing high quality injectors at fantastic prices, there is no reason to just replace a couple at a time.

 

Im looking at getting new injectors i have a 88 305 and i may be putting a 350 in what injectors would be good to buy?

 

Thanks for the reply!

I see you offer 3 kinds of injectors for this engine.
I hope this isn't a dumb question...but how do they differ?
Thanks again!

And thanks for the other replies!

I am definitely going to replace all of the injectors.....as I have no idea how old they are.
