The Feuling pumps are very good and give significantly more volume. They have a tendency to quiet engines down some.
On the downside they have some tendency to sump, not sure I would use them in a TC softail, but on a Glide you should be OK if the bike is ridden all the time.
It depends how much work is being done to the engine, on a 116" I would say go for it, but on a 95" I would be somewhat reluctant to spend thqt much. I do understand that to some 500 bucks is nothing though.
Not that the money is nothing but I can afford it and I ride a lot and really like this bike (plan to keep it for a long time......) Since I am doing some mods, nothing outrageous but 95/heads/cams/S&S gears etc I want to keep the bike as reliable as possible and to help ensure a long life. The oil pump sounds like it might be a good idea for me. Prob peace of mind but whatever............
