Cross-hatch as in the 220 grit sandpaper with directional sanding. Do it before you are on the road. It is a half-hour job, stick on some fresh gaskets, check pushrod protrusion and stroke as per Bentley. Is your pump German Pierburg or Brazilian? A long journey can expand the Brazilian pumps without circlips holding the pivot pin. They sometimes like to drill themselves out of the pump body and leave you stranded ... like my customer in Jacksonville Fl on his wedding day.
My pump is Brazilian. I took out the pushrod and found that somebody had already scored it, but I scored it some more and put it back in. I need to go over to Kombi Haus to get a new gasket. I measured the stroke at 11 mm, which is lower than the Bentley's 13 mm, but since the pump usually works just fine, I assume that the 11 mm is what it wants. There are no shims under the fuel pump pedestal, which means that I have no way of lowering it. So my money is on the pushrod is the correct one. The pump was installed by Ronnie Feitelson of Bustoration in Lake Havasu City when I converted from generator to alternator. He's done a bunch of them.
Interesting thing: the Bentley illustration shows two spring washers under the nuts holding the pump down. I saw no spring washers on my pump. So maybe I have to get a couple of those from Kombi Haus.
Lastly, I've been getting some howls when shifting gears. Justin says that it's probably the probably the throwout bearing singing its death song. That means that the engine will have to come out, so all the other crap with the clutch assembly can be inspected and replaced if necessary.
I think that this is something I'll let the boys at Kombi Haus do, since my back is giving me some trouble and I don't want to risk it further by wrestling with the engine removal. I will give them instructions to check the carb float again, since it will be real easy to get at with the engine out. (see the post at

I'll also let them change out the fuel lines, since it's been about 6 years since the last time I did it. Again, absurdly easy with the engine out.
