Mods when fitting an electric pump instead of mechanical

[Bigbaldybloke]

I?ve decided to fit an electric fuel pump instead of the mechanical one. Is there a benefit or even a need to fit the blanking plate with the deflector strip on the inside to stop oil being thrown up in a similar manner that the lever on the mechanical pump does? I have a plain blanking plate but wonder if I need to change it to the one with the deflector strip?

In theory you don't need it as the oil just get thrown up the drain tube and runs back down. However if your drain tube is slightly iffy you might get a worse leak with out the deflector plate.

When I first got my car running I was surprised by the amount of oil leaking from the bottom of the drain tube on mine with no obvious issues with the tube but now I suspect oil going up there from the jack shaft might of been a factor

Whether that's worth the hassle of getting a new blanker with deflector I'll leave you to judge.

I'll be honest and say that I didn't even know there were blanking plates with a deflector. When I fitted my electric pump a few years ago I just removed the mechanical one and made up a blanking plate using the gasket as
template. It's just a flat plate, fitted with gasket and I expect I used a smear of sealant as well but it doesn't leak.

I'd be tempted to fit what you've got. If for some reason you have a problem then it's an easy job to retrofit a plate with deflector should you prefer one.

I too have only a blanking plate with no deflector. Ive had no problems either.

My DIY plain blanking plate was fitted around 25 yrs ago and I've never had a problem since. One of the few fit and forget mods I've done.

May i suggest you use an Electric "HUCO" Pump from from "Dellorto.co.uk" part n? 133010 and it is designed for use with Webers (low pressure).

+1 to the above. On the advice of Alan I think.

Be careful with the O rings on the adjustable inlet and outlet pipes, they are easily damaged.

Now that's interesting ( for my Stromberg engine)
It is a suction type so draws through the existing pipe without having to make them high pressure secure.
Additionally can be fitted close to the original position so existing pipe lengths might work.
Do you fit an inertia switch ? ( well you should ,I guess) Which one?

I've no idea what pressure Strombergs require.

I have not fitted an inertia switch yet, (I know I should!)
Simple rocker on the RH side of the underdash trim. Which I often forget about and wonder why the engine
is miss firing.
