I got some precision 680's, i'll check em for ya when I get home if you want.

 

Call PTE and ask they will tell you.

 

I've got a set of 780s sitting right next to me. All I can tell you for sure is that those are definitely Precision injectors. My numbers are all different and can't be compared to yours, but at least they all start out with "171xxxxx" just like yours, so maybe that means something.

Also, I hope those aren't for a Honda, because they aren't machined to fit a Honda fuel rail.

 

so yours look eactly like mine except they wont fit a honda right?
ok well they are for a dsm so maybe i still got a deal

Yep, mine look exactly the same.

Precision ships their injectors with really cheap sticker labels that fall off instantly. That's why you always see these inejectors without their identifiying stickers.

 

yeap my precsion"s look the same

 

Be careful. I have 4 different Rochester injectors on our shelf that are visually identical, but range from 55 to 96 lb/hr in flow. All I'm saying is, if you can't numerically identify an injector - don't go by looks.

 

not only that but there's some older rochester inj's that will lock up at higher fuel pressures.. So i would make sure you know exactly what inj your using..
