fuel pressure regulator filter

Evening all, 3 days ago i stripped off my original TD5 head and installed an AMC head from Turner engineering ive since put about 100 miles on the clock with no problems what so ever, however this evening i started tiding up my bench and cleaning away old bits when i realized i hadn't transferred over the fuel pressure regulator gauze filter, how much of a train smash is this as i probably wont get it fitted this month...

All sorted, new gasket and o ring kit installed with filter gauze..

I've come across gauze filters that have got a bit tender and started to disintegrate in situ, so I doubt if it's a problem running without one for a few weeks. The fuel is supposed to have been round the cartridge filter by the back wheel anyway, which should be able to remove particles considerably smaller than the gauze one.

that gauze filter under the FPR is for particles which can result from the HP line between the pump and the FPR cos the fuel filter works only on the LP and return... the HP output of the pump is not going through the filter but directly to the head.

Yes, it goes through the filter, back round the pump one more time and them off to the fuel pressure regulator. I suppose the pipe could start disintegrating, but it's not going to pick up very much muck in a couple of metres of rubber tube.

Thank you for the reply's, its all in and fitted now, but i can tell you i was not impressed at the price of the smallest filter in the world....
