anyone know what this is? its on my #1 injector on my 1993 idi. im assuming its for a timing pickup

yes,that is for a timing clamp. be sure to reuse it if you are using the same size line. do not try to bend the line

what type of timing clamp is it for? can you use this meter? I assume i will need another attachment

Thats the original Rotunda timing adapter found on most every engine be it van or truck setup. The van engine had this adapter located on number 4 cylinder injecter. As posted, you can remove it but you will need to replace the line. On the truck engines all you need is the number 1 cylinder hard line from a van. If you have a van engine then you need the number 4 hard line. We really do not need these adapters any longer. I have the Rotunda timing meter that works with this adapter. For no good reason I have terrible trouble when reattaching the hard line to this adapter at cylinder number 1. So I loosen this adapter and then hand thread the hard line to it. Once I feel the hard line is completely hand tight I then tighten the adapter to the injecter. It works...

Okay thanks. I put it back on. Its on The # 1 line. My 6.9 didn't have it. That meter is a cal equipment magnetic timing meter and tack. It has an inductive clamp and a magnetic pickup for the crank. It was my dads. I never used it. Im thinking if a get one of http://www.tooldiscounter.com/ItemDisplay.cfm?lookup=FERV765-01 Ferret adapters i can use it to time a idi. If it dont work i have a snap on digital advandce timing light that should work with it.
