After a very long hiatus on work to my car, I have acquired a rebuilt Euro-spec M-series IP with ALDA from a turbodiesel in the hope of improving the performance of my after market turbo fitted to my naturally aspirated engine.
I thought the swap would be pretty straightforward, but I have come up against 2 issues that I was hoping for some advice on:
- My old NA MW-pump has an oil feed into the side of it. I cannot see a similar feed for the new M-pump. How is the camshaft lubricated on the new pump?
- My old MW lift pump has a 3-bolt mounting pattern, but the new unit is 2 bolt. I inherited a spare N/A IP with the car that had a 2-bolt lift pump on and it seems like it would work, but the fuel outlet port is much bigger (22mm) on the 2-bolt unit than the 3-bolt so it is kind of useless without either a complete outlet assembly to the hose or some sort of adapter. Any ideas on where I might find such a piece? I feel I should probably just get a complete new lift pump that will connect straight to the flexible hose as I am not sure if the lift pump I have even works. One other thought that occurred to me (tell me if I'm wrong here) is that I could possibly temporarily get away without the lift pump by installing one of the in-line electric Facet-style pumps to do the lift work as the new pump came with a metal blanking plate over the access port to the cam?
