I would interested to see if anyone has a vapor lock issue after locating their fuel pump to the firewall.
Moved mine twenty years ago to firewall and my vapor lock issues disappeared.
I remember calling my local Porsche dealership and spoke to service manager and he said to move it to the FIREWALL!
It's probably more of an issue in the very hot states where 90-100+ temps is more common in summer. GA may not get that hot often enough. Nor does Germany, which explains the OE pump position.
Also, the vapor lock condition only sets in after a a mid to long drive in hot temps, then stopping for gas/food/etc., & then try to restart it.
I waited to do mine for 2 years, not having had problems most of the time in coastal SoCal, but after I got stuck for a couple of hours to cool it down in "beautiful" Blythe at their Denny's after running out to the Colorado River in August to water ski with buddies in 122 degree weather, I bit the bullet & had my guy Hans do it with mine.
As soon as I called him on the issue, he said he knew exactly what the problem was, & would take care of it when I got back home! Back then I lived just a block from his shop!
However, that said - IMHO folks are better off just doing it where Porsche said to & completely remove any chance of V.L. - as they did with the move up front for the 75-76 out of the factory.
Although, your 20 year old install looks pristine!
Mine has 100K+ miles & 8 years of driving crud, then sitting in my garage since May 1985 - so not nearly as purdy as yours!
