First off I'd like to give a big shout out to Frank at SouthBay Fuel Injectors.


After my mechanic said the injectors I ordered were too big, I called SouthBay and spoke to Frank. Frank verified that I did indeed have the right injectors for my engine and that the mechanic wasn't following the instructions included with the box of injectors. Frank then said he personally wanted to talk to the mechanic so that the injectors got installed properly, and that he has dealt with these situations many times before. The mechanic understood what Frank told him and installed the injectors without any further problems. My car now runs great!


I ordered from SouthBay Fuel Injectors based on their reputation here on TGO. This was first class service all the way and I can't thank Frank enough for going the extra mile to set things right with my mechanic. My car runs so much better with the new injectors and I would not hesitate to order from them again.

I'm afraid to even ask, but,,, .... , ... I just can't help it.

How does one install injectors incorrectly? What kind of "instructions" did this "mechanic" not follow?

I've never installed injectors myself, and I'm guessing you have never read threads were people have problems installing injectors. SouthBay Fuel Injectors are a tight fit (insert your joke here) and the mechanic thought they would just slip in like the originals. It appears many mechanics assume the Bosch III Fuel Injectors with Adapter are too wide for the manifold.


The instructions: Before installing injectors, be sure to lubricate O-rings, you can use something as simple as dish soap. "Important" It is suggested that you install the injectors into the INTAKE MANIFOLD FIRST and then into the fuel rail so as not to acquire a leak at the rail.


You will find that these injectors may not have a place for the clips...they do not require clips as the pressure from the fuel rail holds them in.

I just ordered a set of 22lbs injectors from SouthBay Fuel Injectors and was just going to ask about the upper clip.... Thanks!

WeBee thanks for the thumbs up. Sofakingdom I’m glad you did ask. Our instructions come from experience in adapting Bosch injectors to theTpi and it’s a suggested procedure. If anyone has any questions, please do nothesitate to call us. That’s what we’re here for.

Lubricating O-rings would seem to be a normal part of installing ANY O-ring sealed fitting; A/C, power steering, fuel, whatever. One would think (I realize I'm treading dangerously close to "assume"!!) that a "mechanic" would be familiar with such things. It's not really specific to TPI IMO.

I usually use dielectric grease (silicone... D-C 4) on fuel O-rings; seems to be about the most inert and universal thing there is. Much as one would use the same oil to do A/C ones as whatever goes into the system, white lithium grease on oil systems, etc.

All the same, thanks for chiming in.

Good to hear the info helped. Good luck with your project

I did install mine and it's true that they were tighter compare to OEM. I followed the instructions like any amateur would do and it worked fine. It needed a gentle tap with a rubber hammer using dish soap.

Correct me if I'm wrong but i think the reference to installing fuel injectors other than using dish soap on the orings had to do with installing the bosch lll's. Most of the time when mechanics see bosch lll injectors they insist that they are incorrect, some refuse to install them...they are just not familiar with them. One of the biggest issues that we have found over the years with the bosch lll's is that if they are not installed into the intake manifold first and then the rail, fuel sprays out from the top (rail side). That's why we include installations instructions.

Just did mine yesterday, Went in clean as can be. Intake manifold side first, line up the fuel rail side and tighten it down evenly and slowly. Used dish soap as lube. When I first hit the key and pressurized the system there was an air purge sound and a slight smell of fuel but it stopped and cleared up. 2nd 3rd and 4th startup with no sound and no smell...

FormulasOnly

Just a follow up... #7 injector started leaking at the fuel rail.... So Yippeee!!! I get to put that apart again... I''l follow up with what went haywire ...

The joy of DIY. You go from to
Best of luck!

make sure you lubricate the oring when you install them. Leaking from the rail side is an installation or oring issue
