hi. i test fuel injectors regularly. i used to use gas but the post office has a fit and wont ship them with gas in them. now i use water and a digital flow meter. i used to have problems with the injectors if they sat around on the shelf for more than a few weeks. the water would react with the fuel residue and crystallize and plug up the injectors. now i use red RV plumbing system flush after they are tested. no problems yet but i do get worried. is there anything with better non-corrosive and non-crystallization properties that will not react with the fuel deposits and not break the bank?

Use kerosene. Wrap them good. Do not use any water based product as it will pit the inside.
By the way, the post office has no say in it, if you package it correctly they will never know. You don;t need to tell them what is inside, if you need to, make somthing up.
I ship diesel injectors regularly and never ever had a problem.

Good advice on displacing the gasoline with kerosene. The injector cleaning sites recommend double-bagging in plastic so there won't be any smell that would alarm the carrier.

Aren't there any other fluids ...less odorous if in fact there is a sphincter sniffing postal inspector? Mineral oil ..veggie oil ..etc..etc. Something that also won't have any corrosive or residual properties to it??

No offens at all as I am not in your field, but if I found out the injector service center used water, I would be very nervous. Seal the injectors in something good, I am not sure what, but kerosene is not nearly as dangerous as gas. I just got a set of injectors back that had some kind of calibration fluid thru them and it stunk up the whole living room until I got home from work. Nothing ever happened to this package.

Veggie oil will turn to glue in a couple months.
Kinda like castor bean oil.
Maybe WD-40 would work

Maybe try a mixture of 90% rubbing alcohol and a little motor oil. the alcohol would mix with the water and when it evaporated the oil would be left behind. But I dont think it's any cheaper then WD-40
