My new engine was last used with an electric fuel pump, and so the hole in the blocks had a blanking plate fitted.

The fuel pump was not included so just wondering which fuel pump i should get. The Facet electric one like this: Link Will cost me about £40 including all the extra bits you need.

But the original mechanical fuel pumps on minispares are £35 - And from minisport are £14?! So whats the huge price difference for?

If the minisport original pumps are alrite i'll just get one of them for £14 but if i need to fork out £35 for a minispares one then i may aswell get an electric one. Or will the one from my 998 be up to the job of supplying a tuned 1275?

So are there any advantages to the electric fuel pump? How are they wired in - Looks like it'd just be a live and an earth taken from something switched from the ignition?

Also another quick question - The oil feed pipe from the block to the filter - Will my 998 one fit my new 1275 MG engine?

Thanks

no great advantage to an electric pump really on a carb car... more hassle to be honest! - you need to fit it.. ideally supply power through an inertia switch (that trips incase of accident).. also need a regulator to lower the pressure so it doesnt overwhelm the float in the carb...

yes

If you drive your car frequently then the electric pump has little advantage. My Mini is a weekend car and it sits for periods of time without use. With the electric pump you turn the key and wait a few seconds to refill the carb float bowls. Mechanical pumps will do that also... but only while you turn the engine over on the starter.

I cannot comment on the price/quality difference you've found with the mechanical pumps. However, since your car appears to have last used a mechanical pump, fitting a mechanical pump to your new engine will certainly be the easiest option, particularly if you haven't installed it yet.

EDIT: Icklemini and I were typing at the same time. For the record, the Facet pump you've selected does not need a regualtor, it's pressure is OK. However, the safety components he mentions are a good idea.

Ok thanks guys - I'll PM simon from minispares to see what that price difference is all about.

But the 998 and 1275 pumps are different aren't they? I can't put the fuel pump off my 998 onto the new engine when the time comes?

I suppose its always worth changing the pump anyway - As long as its not going to cost me £35!

I haven't worked on Minis with mechanical pumps but I don't think there was any difference in small bore vs large bore pumps. Others will have to address that question.

use a facet electric fuel pump...................

hope this is of help to you...................

Yeah, thanks. Nice install.


I'll ask about the pumps and things - It it turns out i can just use a mechanical one - i'll stick with that for £14
