Replacement electric Fuel Pump

Hello All,

The previous owner or maybe the one before that disconnected the genuine electric fuel pump because it no longer worked. Instead they relied on the mechanical fuel pump on the side of the Holden 202 motor to draw the fuel out of the tank. The previous owner noted that it is taking longer for the fuel to reach the carburettor so this is an indicator that the Holden mechanical fuel pump is in need of an overhaul.

My line of attack was going to be to replace the electrical fuel pump near the petrol tank and blank off the failing mechanical fuel pump on the engine.

As Incisor suggests fitting a pressure regulator close to the carburettor would an alternative be to overhaul the Holden mechanical fuel pump which may boost the fuel delivery to the tolerance that the engine likes.

Or would this be overkill and I should proceed to blank off the Holden mechanical fuel pump and stick with the electric fuel pump and the pressure regulator?

Decisions - decisions :)

Kind Regards
Lionel

You won't need a fuel pressure reg on a 202 as the Stromberg can handle 4.5psi. Any common Facet pump on its own will do the job quite happily.

Cheers Bee Utey,

Thank you for the reply.

Good old Holden's aye :p.

So does this mean that I should be able to blank off the mechanical fuel pump on the engine? Or would I still need it to be overhauled and functioning?

One of the things I have to do is replace the mismatched 173 CC carburettor that one of the previous owners put on and replace it with the correct one for a 202 - a 23-3092 and matching inlet manifold.

Kind Regards

I've had a couple of series LR's with holden motors and had no problems with just using the mechanical pump. If yours is the old sort with the fuel bowl on top it is possible to get kits for them, but I am pretty sure they are relatively cheap to buy new.

Hello All,

After doing some more research and taking everyone's suggestions on board I found a Holden specific site which suggests getting a higher volume electric pump which totally replaces the need for a mechanical pump off the side of the Holden 202 motor. The electric pump is also at a reasonable price too.

Kind Regards

To be honest, I've had more mechanical fuel pumps fail on me than electrical: Ford Essex, VW Golf, etc etc they all suffer from the same issues with the mechanical drive and the silly diaphram.

And before you complain about Leyland and Lukas electrical pumps: I've seen electrical pumps on old Leyland Minis that have literally outlasted the bodywork.

A replacement electrical pump is quick and easy to fit and generic versions are available at most cheap & nasty spares outlets world-wide.

Just fit a nice big in-line filter and you're sorted.

I have a Holden 186 with the "Goss" glass bowl on top mechanical fuel pump.
I then have an original LR 6cyl pump under the drivers seat with ignition power running to it with an isolation switch.

A couple of months ago the mechanical fuel pump died miles from nowhere.
I lifted the drivers seat, switched on the electric and then drove around for another three weeks before I bought a "Goss" replacement which was less than $150.
