Fuel pump

Looks like Veewee do a replacement part? http://www.veewee.co.uk/index.php/parts ... /183vg0080" onclick="window.open(this.href);return false;

And I imagine its increasing rarity and lower production runs accounts for the high price tag. £55 for a replacement (and no idea who actually makes it), £30 for an electric one.

Unfortunately over the years, the potential for fuel pump rebuilds has been eliminated in the general push to sell consumers complete units rather than individual parts. You used to be able to get pump rebuild kits for VW bugs but a rise in imports of sealed units from Mexico killed that off in the late 1980s. Remember it well. There may be somewhere that still sells rubber diaphrams but I think its highly unlikely now. More profit to be made in selling complete pumps. Given the arguably better delivery from an electric pump, and its relatively low cost, I'd say its a no-brainer.

You could try a gravity feed as a test (ie funnel arrangement) and see if she runs fine off that but having had issues with my mech pump that took some time to pinpoint (and much pushing of a very heavy camper) I think you will just become more frustrated by the ailing fuel delivery. It drove me to distraction.

Headed over to Eurocarb yesterday and bought there facet fuel pump. Installed last night and she fired up straight away. I have to say its a bit nosier than I thought, I didn't buy the circular mounts, but i did cut a layer of butyl matt but it didnt do much.

Did you use the noise reducers?

Also, one more question, in regard to the old one. Can I leave in situ and block off?

Thanks for all your help.

Several of us (including me). Best thing I ever fitted in terms of reliability. Lookup 'Facet' in search box, top right. Proper way is with an electric fuel pump relay, second is powered from blue wire from alternator. I confess mine runs straight off ignition now, which technically isn't right but prefer knowing the line is full before I start her up - you can hear when it is by the change of note.

Essentially you fit it close to tank underneath and after fuel filter. You could just cut hoses on your old pump and blank those up.

I had endless problems with engine dying unexpectedly and rough running before I changed to an electric one and to be honest, pound for pound, its the best and possibly only solution on your engine. Not had to buy a mech pump for one of those engines in some years but I believe they're practically extinct now.

The one thing you DO need to bear in mind is that the extra pressures involved mean that fuel hose has to be well fitted, good quality clamps etc so no chance of any coming undone. Also float level needles in some carbs can work fine with a mech (suction) pump but not be able to handle the extra pressure of an electric (push) pump and may need replacing if you get flooding problems. A carb overhaul kit sorted mine.

Nowt wrong with mech pumps though. I'm a big fan of them - when they're working well. Electric ones just give better peace of mind and cost the same or less than a mech pump anyway. £45 a bit much though - you can get a low pressure Facet for about £30 on ebay.

Machine7 is in same town as me - often handy.

Yep, just leave it in situ and block off the inlet/outlet by whatever means. You could unbolt it, remove the pushrod and put the pump back - that way its not actually doing anything and blocking off the pipes will stop any oil leak in the future should the diaphram inside split. Mine is like that although I left pushrod in - couldn't find the courage to tell my old pump it was retired. It still thinks its contributing

Noise yes, but you don't really notice it except when you're idling and the noise is at least some assurance its working. Amazing the difference with a facet when you've had issues with a mechanical pump - at last the pump keeps up with engine demand.

One final tip, if you ever run out of petrol, remember the pump pushes, it doesn't suck, so if you do run out you'll need to prime the short pipe in front of the pump by disconnecting it, let it quickly syphon from tank, quickly reconnect while that pipe has fuel in it then start the engine to push the fuel the rest of the way. Had it happen to me once so just passing that on. Unless you prime short pipe so pump has something to push, it won't matter how much fuel you put in, it won't start. Other than that you'll probably find other bad running probs you may have had will quietly disappear now. For the cost of those facets, its worth keeping a spare under your seat.

Its possible that some good quality nylon bolts (not done up too tight) may reduce the noise. Others may come up with better suggestions to minimise the noise but I've got used to it.

Thanks man, you've been a great help
