By-pass oil filter

[Martin]

When I refit my motor I'll be attaching a by-pass oil filter.

As I bought the filter without any plumbing, I've got little idea where it plumbs into.

I though it would plumb into a tee-piece screwed into the oil pressure light switch hole near the dizzy, but a fellow told me today the take-off should be through the other hole just above the oil pressure switch.  This is currently plugged with a largish grub screw.

So, where is the take-off?

And where should the return line go?  Just behind the fuel pump is another grub screw, and below it a slightly larger hole blanked off with a small hex-head bolt.  Which one of these is the "return" hole?

Thanks for your help.

The inlet of mine is attached to a T-piece in the oil pressure switch hole. I hadn't thought about the grub screw above it as an option. Maybe that would work too. The return goes into the lower of the two holes just behing the fuel pump- where the hex bolt is on yours I guess. Again I'm not sure what the grub screw above is for.

Thanks, Dave.  Sounds good to me.

Hi Martin,
My filter is the same as Daves.Infact I think the Motor reconditoner drilled my Willsonia / oil switch adaptor to fit mine.
