"direct and indirect engines"
this usually refers to the injection method. Indirect injection, injects fuel into the inlet manifold before its drawn into the cylinders for compression and combustion. Direct injection, injects fuel directly into the cylinders once the air has been compressed.

I wouldn't worry about the pump, it was pointed out to me recently by David Miller, (anyone herd from him recently?) that I could muck about with it for a long time and not get it right. Best off finding a local diesel specialist, if you have a smoke problem or low MPG.

Pure veg oil isn't quite as good as dino diesel, but mix 95% dino and 5% veg oil and MPG is much improved. Have a look at the veg oil for fuel post further down the main list.

David's on holiday at the moment in the North of England. We had a pleasant day out in York on Saturday. We parked up in the National Railway Museum carpark side by side his GV and my MR2. Came back to find an F reg, champagne colour Royal Lounge parked behind us. Good condition too. Ironic or what? Anyone lay claim to being the owner of said vehicle?

Ours was in the NRM car park in August, but not this month, and it's silver anyway, but the NRM is well worth the visit, car parks' expensive, but the NRM is free & excellent.

Ian, say Hi to Dave if you see him again!

Regards Rob.

G'day all. Back in one piece...
Andy,to add to Dave's comments above, In diesel parlance an indirect injection engine has a pre or swirl chamber in the head above the piston. The injection taked place here, with the flame shooting out of it into the normal combustion chamber.

A Combo 1.7 is indirect injection (An Isuzu engine actually IIRC) and should have either a Bosch or NipponDenso (copy of Bosch) pump. It'll say on it somewhere, but the only obvious difference I can think off is that on turbo'd engines, the Bosch and denso pumps have a big lump on top connected to the inlet manifold for boost correction, whereas it would stick out the side of a Lucas pump.
