Fuel injector new or used

[burt ragio]

The on going process of gathering parts for the eaton conversion continues. Some parts I am comfortable purchasing used. Other parts I feel better buying new. Such as the injectors & intercooler pump more so on fuel injector. What mfg are considered make better grade injectors from top to bottom ? When purchasing used injectors how do you throughly check them out ?

You can send them out to be cleaned and flow-matched. Even brand new injectors are not usually flow-matched, but IIRC, FRPP does sell flow-matched injectors.

A place like this or one found locally is a decent bet.

[burt ragio]

Have you or anyone you know used these people before ? Any idea what the charge would be ?

[burt ragio]

What used fuel injector would you go with 39lb Bosch or motorcraft ?MotorCraft Fuel Injectors (http://www.fuelinjector.citymaker.com/Motorcraft.html)

Buy Blue 39# injectors from a Cobra and install them. Dont waste your money on cleaning services.

How many Marauders do you know of that have had injectors go bad? ZERO

I don't even know how to respond to this^^^.

OP- I found a place local to me that was way cheaper than the link, that was only provided for reference.
Or you could try this, as long as Zack thinks it's cool:

But that's probably a waste of money, also.

Some of us are broke as a joke and used injectors are the hot ticket. Used injectors, like any other used part, need to be gone through before install IMHO. What are you going to do when three of them are clogged and the motor leans out and you burn a piston?
Yeah what a waste of money...lol

If you are going to spend money on cleaning injectors, you may as well buy some new 60's instead...it will be a good choice if you upgrade in the future and make more power.

massacre, I respect your opinion but buying used parts is cost-effective and 99% of used 39'ers come from low mileage cobras. Buying from someone with a lot of positive feedback also takes some guesswork out.
If you were to buy a low mileage longblock from say...ME, would you take every nut and bolt out of it to make sure it was ok? I think not!

[jdenning002]

How about cleaning them your self? And replacing the o rings and screens?

Worth it or waste of time?

I have a set of 39# I was using with my paxton kit for about 50K miles...

Bottom line is this:
An Eaton swap is done to save money over buying new parts.

If you want to take the time and spend the $$$ to ensure your used parts are in perfect working order, buy a Trilogy.

The reason Eaton swaps are so successful and foolproof is mainly in part from using OEM parts and sourcing them from low mileage Cobras.

[FordNut]

I've purchased low mileage used injectors 2 times and never had any problems with them. The first set I re-sold and the buyer was happy with them.

We just had a used 60lber go bad on a customer car. It washed the rings out on that cylinder.

Had the injectors been gone through the customer probably would have been spared that problem.

Just saying...

Interesting... So it failed in an open state instead of closed, running the cylinder too rich instead of leaning it out.

Just saying...

A: It could have failed that at that very moment.
B: Testing may not have found a problem if it indeed went bad that moment
C: Did you rule out the wiring yet?

A and B are true, and yes to see. :P

Yeah Zack, sorry if I came off like a jerk, I've been throwing up all day and am just now able to hold down some soup.
I do respect your opinion also, I just didn't understand your reasoning behind it. I get parts from junkyards, and obviously I am going to go through and clean, paint and check through any parts before they go on my motor, that's a given. I haven't spent all this time & money building the motor & degreeing the cams, powdercoat, fabrication, etc. just to have it all loused up by a crappy fuel injector. They don't fail often, but they do fail, and it's cheap insurance IMHO.
I was merely giving the OP an option, in case he wanted to go down that road.
Sorry for being a dick about it, wasn't very nice. :beer:

Do our stock injectors need cleaning from time to time? Or, would cleaning improve their function (like those shiny posters that you see in pretty much every shops waiting room)? I've been wondering about this, what with 260000km on the clock.

I noticed a much smoother idle and a little better responce after cleaning and servicing them @ 30,000 miles.

To me that is just a part of maintance work like changing out the gear oil and tranny fluid and so on.

The cleaning fluid was dirty after the first time soaking so that was a clear indication of it being needed to me. And a couple of the filter screens were a little bit filled with crud.

[jdenning002]

I called the guy from the website in the first post, (http://www.fuelinjectors.com/ (http://www.fuelinjectors.com/))
He wants $189 to clean them and return shipping. OUCH!

Way too much $$$ when you can buy a low mileage set for $125-$150...

Self cleaning (soak in seafoam) and new o-rings and screens are a fine idea and cheap, but probably not 100% necessary though.
