Shipping instructions


We have changed the way we accept injectors, we are now doing this to keep from getting overloaded and insure better turn times.
Please email us at info@witchhunter.com and include the following information:

Be aware that we don't always get all of our emails, so wait a day or two and resend.

Your Name
Number of injectors and what they are out of.
Any special instructions.

I will send you a form to fill out and enclose with your injectors.



It is best just to leave the o-rings, seals, etc. on your injectors, as we will return them anyway. At a minimum, leave the parts on at least one injector so we can ensure that you get the proper replacements. Normally we know what to use, but in some cases where the customer is using them in non-stock applications we like to be sure.

Please do not send fuel rails, hold-down brackets, clips, etc.

As a courtesy to us, please clean the grime and dirt and grease off the injectors. This business requires a clean environment to ensure good work.

We will charge $2.00 each for any injector that are not serviceable or any extra, or spares sent in to us. It may be a good idea check the coil resistance of each injector before sending them in to verify that that are within 10% of each other. Coils can fail on any injector, especially those are known to have coil winding issues, see our "Problem injectors" page has more information on this.

It is advised that you install and use injectors within 30 days after you receive them back to minimize any chance of them sticking. If you don't plan on using the injectors for a long time, it may be best to wait before sending them in.

If they do have to sit for extended periods, don't allow them to dry out and store them in a plastic bag or airtight container and store indoors.

Packing and shipping

Wrap your injectors individually in a paper towel and put them in a plastic bag to keep the package from smelling of gasoline. This keeps the shipping folks happy.

It is recommended that your injectors are shipped in a box and not in a padded envelope to keep them from getting damaged.

Please get delivery conformation or a tracking number so you know when we receive your injectors. We are known to get a bit grumpy when people call and interrupt our work and ask if we have received their injectors.

Please do not ship your fuel rails or mounting hardware, or additional charges will apply.

Expedited service

We do not offer this service at this time.

Turn times

Please check our current turn times on our home page.

Our current turn times can change depending on what comes in on any given day. Unfortunately we don't have any control on what arrives each day. We will try very hard to get your injectors completed in a timely manner while maintaining our quality of work.

We typically work 80 hours a week, so it would be appreciated if you keep unnecessary phone calls to a minimum. We don't mind technical questions, but most other information can be found here on the website.

Please check your tracking information if you want to know if we received your injectors.

While you are waiting...

Now is a good time to replace your fuel filter and check the entire fuel system, vacuum hoses, etc.
In cases that the vehicle has sat for years, you should to drain the old gas, inspect the tank, pump, and all other fuel related components.
Having debris, water, or metal shavings can get into your newly serviced injectors and cause problems. Note :We will not re-clean them for free due to comtamination.
Don't add any fuel additives at this time, as it will interfere with the ECU learning the serviced injectors. These can be added at a later date if needed.
