Thanks , but on this picture the lower hose seems to be located elsewere...

A picture of a bare firewall  would be great.


thanks

If you have the original firewall pad it should have perforations where the holes should be.

Thanks Shvegel ; no : i  have the forum-firewallpad  without the perfo-indicators : do you have a pic of your underdash to Sandenpump hose routing?
Thanks Rbouch8828 ; is the a chance of making a picture of the area behind your expansion tank?


I not sure witch dryer/filter to use  and/or  hose-routing  , because of a possible collision of the lower hose to dryerhousing..

thanks

My car is with Joe in Blacklick right now. Perhaps Joe could do that for you. Why don't you drop him an email?

I found this picture that I took of the firewall prior to refinishing, that shows the 2 Frigiking hoses. I have marked them with arrows.
