Vacuum wiper motor line routing M38A1?

I'm working on getting my original vac wiper motors working on my just purchased M38A1. Of course what would be helpful in making the motors move would be if there was actually a vacuum line running from the fuel pump, along the block, to the firewall and from there it is just rubber tubing.

I've attached pictures showing the area in question and my question is this, can anyone share a pic or two of what the original components and routing of the lines looked like from the fuel pump to the firewall? The pics I've posted show the vehicle as purchased, with the vacuum ports plugged with the red caps. I've looked in the TMs but the image is very poor quality and not a close up to show which port supplies the wiper motors.

Also any guidance from those who have run this line before would be helpful regarding the thread size of the fittings and the hard line.

Thanks,
Wade

Hey Wade, take a look at Wes Knettle's photo album over on www.willysmjeeps.com . I'm sure he has some pics already posted - I remember the question being asked a few times there, so do a search if you can't locate Wes's pic. I'll see if I can get a link to his album.

I did a quick search on my phone and didn't find one in his album, but I can't see well on this phone. Here's a link to his album

Thanks for the lead. I'm not registered on that site but I will be in a few minutes and see what is posted.

A lot of good info there - it is dedicated to preserving m38s and a1s.

I got enrolled in the other site and you were correct, he has photo documented much of what I needed to see. His example vehicle is an M38 so the source of the vacuum is different coming off the intake manifold but the overall routing is similar. Thanks again for the lead.

Wade
