Hey man! Before the intro police come around and give you a ticket, tell us about yourself here: http://www.jalopyjournal.com/forum/forumdisplay.php?f=18 In the mean time, there is a link in my signature line below that will direct you to some Early Hemi Tech. I would love it if you posted that very question in the section related to fuel pumps and such. Cheers! Scooter EDIT: I added a link in the HEMI Tech section to this thread.
I've removed the one on my 241, and replaced it with a block off and electric one so I could get my alternator in there. However, since I kept the 2bbl stromberg I had to order a 1-4 lb pressure reducer. That Said Maybe I can help you with your problem, as I now have a stock one I am not using. And it worked when I took it off last year. I would think the 270's would work though. Is the 270's one that runs off the front of the cam? (long nose cam)? Just noticed your across the pond. Could be a bit to ship if your doesn't work. I'd suggest double checking with these guys though. http://www.hothemiheads.com/
The fuel pump from the 241,270,315,and the 325should be the same. The 315,325 are the high deck version of the 241,270. OLD HEMI
There is one part # for 53-54, & a different # 53-55. over lap, I'd agree with Old Hemi, it shouls interchange.
