1982 300 td Radiator Neck Failure

Well sure enough, my very clean and tight TD's radiator neck failed while driving and I am glad I am an assiduous gauge checker. When the temp started heading up above 100 I pulled off the road and found the hose off and quite a mess. There was enough of the neck remaining for me to reattach the hose and make my way home.

I am wondering if I can use the reinforcement kit and a piece of ABS or some such to fashion a new radiator neck instead of buying a new radiator. I'd much rather spend that money on replacing the rear window gasket of the CD.

Thanks for your help.

electric fuel pump added to my 1984 300 CD

1984 300 CD
I added a Mercedes Source electric fuel pump, no other fuel system mods. After inital installation the pump would audibly cycle slowly at idle, and pump speed would aduibly increase with engine speed.

suddenly, the pump now runs at high speed constantly, idle or at highway cruise, no detectable difference. Is this a problem or normal?

Also, any ideas of a material to use to isolate the pump from the chassis to lower the audible pumping sounds?

1985 300TD Turbodiesel - Boost Intercooler - Any Experience?

My 1985 300TD Turbodiesel runs on SVO. The car has good compression and runs great. The car gets to 60mph in about 13s which I believe is to be what's expected from a well tuned specimen. My aim now is to improve the performance beyond that. I have installed some of the performance-enhancing modifications recommended on this web site, including Monark injectors and a fuel boost pump. (Of course I also have Kent's performance tuning manual which has been very useful;-)
