Hey guys buying some used injectors they are 720 is there any way to tell the size of the injectors? i don't want to get riped off and buy 720 when they are really another size then what i want.

 

if you are trying to get a verification before hand, requst a picture of the injectors across any seriel or marking information, and if you wanna be REALLY particular, have em laid across the days newpaper, then call the manufacturer of that injectors and very the code aginst their database. otherwise, based solely on a picture, a 7XX may look alot like a large 6XX or small 8XX. hope its a help a. you hadnt posted about any particular brand, otherwise id be glad to verify against a known. good luck.
