Fuel lift pump for VP 2000 series.

[NealB]

Do any of the resident experts know if the fuel lift pump, on the VP 2000 series engines, has ever been redesigned, please?

I've just bought a replacement pump, from Repower Marine, who asked no questions about the age of my engine, but someone on a VP user FB group seems to think it's critical. (Edit: they didn't ask about the age of my engine, but they did ask if mine has a removable, or sealed, top. I didn't realise how critical that question was: I do now) .

Here's his comment (copied and pasted):

"I purchased VP pump last year. It did not fit. I have a 1984 VP2003 and picked the correct VP number for the old version. Coming was the new version with the old number. Cam can not lift the new pump - missing 5-7mm of pump stroke. I am left with other retrofit pump which has almost the same lift as the original - within 2 mm of lost pump stroke".

Any informed thoughts would be most welcome.

I've also emailed the technical guys at Repower.

Thank you.

I know there is a more modern lift pump. Whether this is 'critical' is doubtful. It's a lift pump not a dosing pump.

Thank you.

That sounds reassuring, and makes sense to this non-engineer.

I'm obviously keen that the replacement delivers enough fuel, but I'm equally keen that the new pump is a nice simple swap for the old eg needing no fiddling around with fuel pipes, to get it mate up.

I'm surfing this learning curve.

There are, indeed, 'earlier' and 'later' pumps.

Key differences (that I now know of) are:

- the older style have removeable tops, whereas the new have sealed tops
- they have different drive lever profiles
- the input and output connectors, between the old and the new, are reversed.

The new type requires new pipes; the old ones aren't compatible. The old type pump is no longer available, so if you need a new pump, you also need new connecting pipes.

I've heard good reports from people using these, including that it's reliable, and a strarght swap:

Fingers crossed, as I've now ordered one.

Yes ...... you're right!

I'll edit my post.
