Perhaps a little 'off piste' as this thread is concerned with scuttle tank cars and my RP is, of course rear tank, I would nevertheless comment as follows:-
About three years ago, shortly after I acquired my car, I had the tank professionally cleaned out and the outlet gauze was removed as it had become holey and was simply trapping rust flakes below it. Its continued presence would also have made sealing the inside of the tank somewhat problematical.
A short time later, still being plagued by fuel starvation on long second gear hills, which are common in this neck of the woods, I replaced the front to rear fuel pipe. Having no spare inline fuel filter to replace the one on the old pipework, I simply coupled the new pipe to the tail to the inlet side of the pump with a short piece of hose, meaning to replace it with a new filter, which, as with many of these things, never got done.
As many of you may know, my Seven is very much a working vehicle and does anything up to 5000 miles a year, mostly on mundane running that I no longer mention in these annals at the risk of becoming a bore. For instance, yesterday, the little car was driven to the horses (who are now this side of the mountains at Llandderfel) and on to Wrexham to drop off a friend of my great grandson, who had stayed for a few days, at the railway station to catch his train home, before wandering off to work, a round trip of about 80 miles.
Since I have replaced the fuel line, despite the lack of an inline filter and relying solely on the gauze filters in the pump and carburetor, I have not had any further difficulty with fuel starvation and, when the gauzes have been dismantled during routine maintenance, there is very little 'crud' in the well of the pump and none in the carb itself. One is driven to the conclusion therefore, that either the fuel is very well filtered before delivery or that the gauzes are doing their job.
