I have a 1991 Toyota Pickup Sr5 3.0. One of my injectors is leaking from where I can see it is where the plug goes in at. Can I get a rebuild kit for this issue?

 

I would call Gordon at Witchhunter. He is the master of injectors. It may only need to be serviced, if it needs more Gordon will tell you before you send it in. Just tell him what you are seeing when you call the shop.

Napa sells an O-Ring kit P/N 2-12069. If its an external leak includes 4 o-rings and does one injector cost is approx $5 per kit

 

while you're in there you should consider yanking em all and getting them flow tested. made a huge difference in fuel economy and made the ol girl run much smoother. If one is on the brink then I'm sure you'll see problems w the others in the near future.
the shop that did mine replace all o-rings and plenums on my injectors as well, for a very reasonable price (around 100 cad if i remember correctly)

 

If you are talking about where the wire goes into the injector I don't think there is a rebuild for that.
On my 89 V6 4runner I had an injector leaking at the wire termination. I had a shop replace it and asked if I should get them all replaced and the tech said "no". Guess what, less than a month later another was leaking.
If yours is leaking at the rail or the manifold its an cheap and easy fix.
good luck

 

I agree that if the leak is coming from between the main injector body and the plastic part where the connector plugs in, the injector should be replaced.
and if you're replacing one, you should at least have the rest checked for flow rates and clean the older ones if necessary, or replace the whole set for a balanced/flow-matched set.
