Thread: leaking fuel pump fittings

hi my 4bd1t county is leaking diesel from the fittings on the lines that come out the top of the in line fuel pump.
does anyone know how hard this is to fix, if its just a matter of tightening the fittings or should i replace them.
any help would be much appreciated

If they are leaking your probably sucking air to the isuzu washers are rubber on both faces and are really one use only I recently replaced all mine with plain copper ones at 1 $ each .interestingly I had the supply pump rebuild today $100 which was in very poor shape once pulled down .
