Need electric fuel pump for 1980 CU engine Devon

[mgbman]

As in my recent post about a large oil leak from the old mechanical fuel pump, the advice is to remove the old pump , fit a blanking plate and fit a new electric pump.

I feel this is the only way forward and I would appreciate advice as to which pump to buy and how to fit it and wiring etc.

Presumably Brickwerks would have the parts i would need. At the same time I feel it would be good to renew all fuel pipes from tank to carbs. Which petrol pipe would I need please.

Hello,

Before you rush out and spend your hard earned..

Below are some pics to show you the fuel pump and so on from

(from midway down page 4 of 'Ooops')







Providing the bakelite spacer is ok, then all you will need are the gaskets and a SMALL amount of high quality sealant.

Look before you leap.. if the pump has been changed chez VW in the past.. it will probably have torx head bolts..


Replace the little flexy pipe with new..

Tighten to 8 to 10 N.

It does seem a really crazy palace to put a fuel pump...

These were commonly fuel injected so pump next to fuel tank..

But for the mechanical pump versions......thats the only place you can put the pushrod from the camshaft to the pump.. Aha..

Cordialement..

Hello Sarran1955, thank you for your response and the pics of the fuel pump.

Should I take the pump off and have a look at it and try to repair it or look to get a new one.

You may have seen my recent post about the large oil leak from the pump when the van was parked up on a steep driveway.

The oil seemed to be dripping from the pump vent pipe and as the van has not been started for two weeks most of the oil has been lost onto the driveway. The dipstick oil level is now well below the minimum.

I would much prefer to have the mechanical pump as fitting an electric pump seems complicated.

What would you suggest I do please.

Drain oil..clean as best the underside of the engine..do pump change..fill with ordinary mineral oil..on the flat.. put a large piece of cardboard under the engine.. held in place with a brick.. start and run engine.. check for blatant leaks.. leave over night.. drips down the sides are rocker cover gaskets..drips where the engine meets the gearbox is crankcase oil seal..drips off the pushrod seals will be on the edges of the lower tinware ..drips under the sump plate speak for themselves..

Please be VERY CAREFUL and thoughtful about the amount of pressure you put on the sump strainer nut..

Because that's where this whole story started

one less electrical gremlin...

Well, I put more oil in the sump and oil poured out of the fuel pump. Took pump off and old fuel lines. Pump stroke working well and it pumps fine but cannot use it now.

I made a mistake buying a new OMEGA mechanical pump which is faulty and poor quality and I have decided to go electric.

I have seen lots of posts on electric pumps but as a beginner and a senior citizen I would like some simple help and advice about what I would need to convert to electric pump.

I understand the basics, such as take out pump push rod. fit gasket and blanking plate (where do I get this and can I use the old long bolts). Fill sump with yet more oil.

New fuel line from tank to new filter, new fuel line from filter to electric pump and new fuel line from electric pump to carbs (original solex ones)

I have questions about the pump, I am getting the quality Pierburg from Brickwerks of course, but would I need a pressure regulator? Where would the power feed come from? Do I have to have a safety relay circuit fitted? Can I just have it so the pump is switched when the ignition switch is activated.

On my old MGB it has a simple setup electric pump which works as soon as the ignition is switched on, no fancy wiring no relay circuit and very simple and it works.

I need to get the van started and I want to have a simple setup so I can move it off the steep driveway.

Please would you help.
