I understand that a number of Maserati cars, manufactured in the 1960's, were fitted with Lucas mechanical injection and often had belt driven fuel pumps. Does anybody have any idea where I might be able to buy one of these belt driven fuel pumps?

Thanks

I've never heard of a production Maserati with Lucas FI using a mechanical fuel pump. Original equipment for these cars (3500GTi, Sebring, and Mistral) was an immersible Lucas electric pump in the fuel tank. The fuel metering system was mechanically driven off of the center of the right camshaft, so that may be what you are thinking of.

The only FI system I can think of that used a belt or chain driven pump would be the old Hilborn / Kinsler / Enderle design, generally seen on American engines in vintage hot rods, dragsters, and sprint cars. An interesting but comparatively crude system, it was reknowned for maximum performance, but not efficiency or flexibility.

Cheers,

Hi Steve,

I believe I've read elswhere (although I'm no expert on the matter) that this FI system was notoriously problematic needing regular maintenance to prevent fuel entering the sump and diluting the oil. many owners removed the Lucas setup and reverted to carburretors to get around it. If you're looking for a pump then perhaps you are planning to re-instate the system on one of these cars, in which case I would seek professional advice....No, not the 'laying on a couch having you bumps felt' kind of advice :D Take a look on Enricos' Maserati pages for information or speak to a Marque specialist: Bill McGrath in the UK or Olaf Boeking in Germany perhaps. Don't know of any in Boise but I am sure our friends here on the forum will advise you of US based experts. I bet MIE could supply the pump for you if you were determined to go for it.

Good luck.

It's been 20 years, but as I recall the earlier Lucas injection systems lacked a seal at the drive shaft between the high pressure fuel and the cam cover. Later systems had double seals with a bleed.

Most of the problems came from unfamiliarity with setup. Weber conversions were common, but you lost some torque as I recall.
