Fuel Injection Cleaning Kit?

[Matthew Jeschke]

I suspect I have dirty injectors... In the least I have old vehicles with old injectors. Looking to buy one of these fuel injection cleaning tools that hooks up to your air compressor and fuel test port. It injects cleaner directly in the rail.

This tool would be excellent if it also had a couple different fittings and somebody could inject say seafoam through a noolze on the tool if they had a few attachments.

Anybody know of a version of the tool with various attachments to inject cleaner through say vacuum ports, inside the air intake, etc?

As per Lake Speed Jr., at Speediagnostix, recommends using Chevron Techron Complete Fuel Injection Cleaning solution about every 4th tankful.

You don't even need that. You can use cans of Echlin to clean the injectors. We connected them to our fuel rail in the 1980s and 1990s, pulled the fuel pump fuse and the engine ran on the Echlin until it ran out. Worked great. Last time I checked it was still an GM/ACDelco product but do not remember the number. The adapter was either like or the same as the one we added those cans of refrigerant to the AC system.

Nowadays I just run E85 to keep the injectors clean and if running gasoline for a long time, Techron like Ron recommends.

Yea, I just run gas.

I use Techron, as well.

Ditto on E85; I run it full time since I can get it in town, and the Hoe passes emissions easily. If not using E85, run the Techron periodically, paying attention to the dilution requirements. You'll probably need a couple of bottles for a full tank of gas.

One of my wives (LOL) had a Bronco II (2.9L V6 manual, not that it matters here) that wouldn't pass emissions. At that point I wasn't working on cars so we took it to the dealer and had the injectors cleaned, but I'm not sure what method was used. First emissions test after that it barely passed. We ran several tanks of gas with Techron over the next couple of years, and the next test it passed with flying colors.

I run the Techron Complete Fuel Injection System cleaner. The 20 ounce big bottle. Said to treat 20 gallons. My tank is 26 gallons. I dump a whole one in every 4th tank fill up. Since I treat 1/4 tank as empty, I figure my dilution average is about right. Fortunately there is no emissions test down here, like there is in the Portland area.

I get the Techron 20 ounce bottle and it is $16.99 a bottle ay my O'Reilly store. About once every 1.5 to 2 months, they run a special of "Buy one and get 1 free" and I get a whole case then. I sell it to my driveway customers for $25 a bottle.

There is only 2 E85 fuel stations in the greater Eugene, Oregon area. One Chevron and one Shell station. Both are on the other side of town.

I'll be at a loss if/when I move away from here. When I was working and driving to the office, I could get E85 about 6 miles into my drive on the way there. Now a station has opened up about 2 miles away, which suits me just fine. Same brand (Maverik; took over the

stations here) and the mix is consistently around E70.

I have NEVER seen E85 in my area.

you can replace all the injectors with brand new ones for less than half the cost of that commercial tool
but we have already had this discussion............
your options are make your own tool with basic fittings, buy some china crap, pull them out and have them serviced/cleaned, have a shop do it with that commercial tool they probably already bought that generates money for them.
or buy it, use it and try to return it........

I found a version with different attachments. It was $70. You can use it to clean intake as well. It seems like a good idea to have around, the seafoam intake cleaner is getting spendy, when a person could just use this thing and not have to pay for aerosol cans.

Additionally, I like idea of directly applying a stronger dose of injector cleaner to the rail w/o having to dismantle everything. I googled and saw some pictures of the aerosol can that attaches to the fuel rail test port but didn't see it for sale?

Herko was $270 for injectors. I'm going to try this for now... Until I can find a few sets of used flex injectors on the forums. Then I'll take the closest matched ones and put them on the truck. I can use this to flow test them if I can find a rail as well w/o having to rig up a pump, pressure regulator, etc. etc. etc. as well.

They don't sell E85 anywhere I know of around where I live.

There's a Speedway on 795 W Sahuarita Road that has E85 according to GasBuddy. $2.65 a gallon reported this morning.

Lake Speed is correct. Techron is the only gas additive that works. In your case you might try a can a tank for about 5 tanks of premium. Solved my injector problems on my 2010 CTS V. All of a sudden it looked like a fog truck on occasion at 40,000 miles when I would start it. Sold it at 208,000 miles without a single repeat of the fog and never added Techron again. I was using Top Tier fuel after that.
