is there a place I can buy this fuel filter at fuel pump inlet line? what is the part number?
Thanks!

I got hold of Niemoller in Germany this morning who advised me the the filter for the Bosch Fuel Pump is no longer available. Thinking about it, if you have the in-tank filter which is a very fine particle filter, is the fuel pump filter really that critical? There's also the fuel filter on the engine side as well.

I've also ordered a new fuel tank from Niemoller, which the guy I bought my car from has willingly agreed to pay for.

I had my tank removed, acid bathed and internally coated to get rid of rust problems (lots of it). The job was done by a well known italian w113 specialist that granted that no internal tubing or fuel passages would clog  during coating process. Next week the tank will be reinstalled. I'll keep you informed.

1.  Opinion - the pump filter is there for a reason.

2.  Anecdote - I had a 280SEL for a time with a tank in poor condition.  I had it cleaned and coated and continued to have problems with fuel starvation.  What I found was that the tank strainer was OK, but the pump filter was clogged.

If you have a new tank, you will probably be OK for a while.  But I suggest that you look for a used pump, condition unimportant, and use the inlet filter and fitting out of that.  You could also install an inline filter between the tank and the pump.

Mike, I think that you can find the pump filter at www.tecning.com.
They are the ones that stripped and coated my tank.

Chuck's inline solution sounds eminently sensible if the part is NLA, and very easy to accomplish. There are filters in clear (ie almost transparent) housings that would enable you to see if there was crud coming from the tank, and that way know if there is a problem with the filter or whether you need to look elsewhere.

This might be a long shot, but the Triumph TR6 that I once owned, had a similar issue when tank levels reached 1/2 full - it was the fuel pump (Lucas crap) running hot…

Holy Cow, Gary, you can have a dig at Lucas, but for a North American have a dig at British beer is several steps too far!!! Please don't even go there.  :o

But back to Lucas, (where you're safe), I learned that Lucas thought they'd managed to invent the first computer, but they couldn't figure out how to make it leak oil.

Ah, the wonderful world of Triumphs.  You have to have a sense of humor.  I tried to autocross a Spitfire and broke just about everything but the lucus stuff.  That is what led me to my SL. It had everything I wished the Spitfire had.  No regrets, the spitfire was fun to drive, it was the way I tried to drive it. I have a friend with his original  (kinda) GT-6.  He has a spare or 2 of everything. but we digress....
