Can anyone direct me to a supply source for the high pressure oil feed line for the MFI Pump. I don't see on e on Pelican and Stoddart came up blank as well. Thanks, Greg

Pressure would be what ever the system pressure is from oil pump

Thank you very much! That's exactly what I'm looking for. I guess I missed that in my search.

A question.
I got rid of my feed line and the return to crankcase line...and filled the pump with a good quality oil on the advice (I don't remember who) of someone that said it would prevent leakage of gas into the main oil supply.
I changed the oil fairly often...and it always looked clean...and did not seem to rise at all...so very little gas getting into it I guess.
Right or wrong?

I haven't heard of that but it would certainly solve my leaky ( and quite new) oil line issue. I would also like to hear opinions on this question.

If you ditch the oil feed a la RSR style, you must have the pump ventilated. Gus can do this for you, but here's a twist-- now you have to change the oil in the pump periodically. I suppose you could get one of those suction things to remove the oil, but I personally would not stand for removing the MFI pump once a year, it's just too much trouble to R&R.

The Factory race teams were pulling the motor after every race (sometimes during!) so for them, no big deal. But I don't really see any advantage for a street-driven MFI car, and in fact, a lot of the heating of the pump thermostat comes from the oil, not from those flimsy paper hoses.

Long way of saying leave everything alone, replace the hose with the correct Cohline piece from our host, and call it cool.

Thanks, makes sense to me.
