Fuel pump choices, advice please

[Paul Kelley]

My fuel pump seems to have packed up (no clicking and not responded to tapping). replacement options seem to be SU original with points, same but electronic, and Rimmers offer an alternative cheaper electronic option. Any views on which way to go in terms of quality/reliability?
Thanks!

Many of us are using the one supplied by Peter at LD part. Straight one for one swap and is electronic. Also supplied by a Trader you can trust. I would recommend it if asked.


Just a thought ? have you checked the inertia switch is giving it the feed it needs. try bypassing it.

Many thanks Ian - good point about inertia switch but seems ok. I didn't find Peter's pump on first search but have found it now. Good price too and I always use Peter first when I can. Will try a few final checks and then go with LD.
Thanks again

However as Ian above suggested I also have this pump. But also on his suggestion had to use a pressure regulator with it.

Mine's from Peter, it's excellent.

Also depends what carbs you are running. My SU pump gave up then I purchased one from Peter but still found that I had problems. I switched over to a facet pump a bit noisy at start but quieten down. Then I am running a Holley Carb. i have also been advised to fit a fuel regulator. Yet to do.

Hello,
My first choice is the Japanese Mitsuba - both on the Stag and the TR6. Not cheap, but reliable.
Best wishes,
Dieter.

Thanks for the additional info guys, all noted.

I also run one of these Paul, http://www.ebay.co.uk/itm/SYTEC-PRO-...gMft8Q8sgGMZwA


Theory being it cuts down on needle vale leaking issues.

Hi Ian,
Whereabouts is the regulator installed in your stag?

Is there 12v at the pump?

Not able to provide a picture at the moment Julian, butt it's fitted after the filter under the bonnet on the pipe that runs across to the carb T piece.

Thanks Ian, I couldn't see it in your underbonnet picture (relay thread) so is it before the filter, tucked in close to the wiper motor?

Also, would it be as effective if it were installed close to the pump do you think?

I'm interested because I'm anticipating having to put one on my car.

This year theres been 2 sets of float valves fitted & i suspect there is still issues with them.

Currently running an electronic s.u. pump & grose valves.

I have a malpassi combined filter & regulator, but prefer the size of the sytec one you have.

The relay picture is pre fitment. It is fitted midway in the braded fuel hose you can see and because it is very compact and light I have secured it to the twin bonnet cables I have fitted. I did this as the unit itself has no fixing points just the 8mm threaded tails for the hoses. You could make a U shaped bracket that could go over the tails before you fit the hoses but I am more than happy with mine and it hasn't been an issue so far. The great benefit of having it under the bonnet is it takes seconds to adjust if you so wish.

Regards installing it closer to the pump, I do wonder if the pulsing action of the fuel could shorten it's working life. Having it further upstream I would suggest tends to have a more constant flow of fuel being delivered to regulate. Just a thought

Hi Ian
Can I ask if you fitted the regulator because you were having needle valve issues due to some characteristic of the LD pump? Or was it a separate unrelated problem/ Or indeed just a precaution? I'm just trying to weigh up whether I actually need to do this as well. On a related point, is it also wise to replace the inertia switch whilst changing the pump? I would assume it would work the same with a new but different pump, but I'm also wondering about 40 year old inter-connected parts. Many thanks
Paul
