Dan ,
I was digging thru ( whats left of it ) my parts car and found this bracket / clip , is this the clip that you are thinking of having reproduced .
At first glance I almost tossed it but then I thought to my self , HEY wait a minute Ive seen a picture of this thing .
If this is indeed the fuel line clip you could Borrow this one to get some re made . The only thing i,m curious about is the way its made it appears that there may be a left and right ?
.
I fit it up to my oil pan ( if thats where it fits ) and it fits on one side good but not the other side .
