Thanks bd, I'm still on the look-out for one although I'm not sure that a s/h will be any better than mine. Is anyone selling them new?

No sorry I've not seen a new one for a long time and even rebuild kits are now very scarce and far more money than they are really worth.A blanking plate which is just a farty bit of metal with a coouple of holes in it is also expensive but eay to make and probably a conversion to the older type of SU pump is the easiest way to go.

Spent some time fiddling with the P5B today. I fitted a new electric pump instead of the mechanical pump, made by Huco but almost identical to an SU to look at.

I'd already sorted the ignition side of things fortunately. Turn ignition on, pump primed up correctly, and it started first turn Smile It hasn't been on the road since 1999 so I was keen to see how it ran - sounds magnificent Cool Still not 100% sure whether to keep it, maybe instead of the Standard, or sell it as I really need to cut down a bit now, time will tell!

A result! Sometimes when these have stood a long while the oil pumps need priming,it must be pretty sound if it didn't.
I've managed to locate some repair kits for the mechanical pumps and have ordered a load of them.A lot have been converted to electric pumps.
I spent nearly eight months fiddling with Humhrey,my P5b,but taking it out with all the silly niggling little problems sorted made it all worthwhile.Pottering along in relative silence one minute,then flooring the accelerator and feeling a fourty plus year old,thirty hundred weight car sling itself down the road is a pretty satisfying experience.
It's no good if you don't like being noticed,these cars attract people attention and if you need to convince the wife they are also an investment.
So,get your spanners out!

Hi bd, yes I read about priming the pumps but fortunately this one registered pressure simply by spinning it on the starter.

All but one brake light worked straight "out of the box" surprisingly, despite being off the road 20+ years. The rear brakes are sticking a bit, so I might have to investigate them (puller required?), otherwise I suspect it wouldn't need much to get it back on the road. The PAS seems to work ok with no irregular noises, battery is charging etc etc.

I haven't tried the 8 track yet - when I went to view it, the glovebox was full of cartridges, but when I went to collect, they'd vanished. Plus I'd sold a box of cartridges only a week or two before at a car boot sale, typical!

There are a couple of areas needing weldy weldy, but very localised and no rampant rust that I can really make out. A bit in the rear door shuts, and near the front jacking points, otherwise just a few scabby bits on the door bottoms where they tuck under. It had brand new front wings on it 20-25 years ago, so they're like new which helps, plus the auto box has only done 500 miles or so before the guy stopped using the car (due to the cost of his daily commute to work!).

The mechanical pump is marginal at best even when new - most repair kits contain only valves, sometimes both sizes that were used, and diaphragm which is not really good enough as the plunger oil seal is needed as when worn this will actually pump oil out the engine via the oil vent in the pump - not a lot but enough to make a constant drip.

Some kits had this too but the real problem is wear in the linkage joints whih reduced the throw and pumping capacity so that missfires/flatspots will arise pulling hard.

This must have the been one of worst examples of Leyland penny pinching on a quality car and that was even before the BLMC days when things got even worse

unlike yesterday, when I tried to demo it to dad and it refused to play ball. I think some muck or old fuel in the bottom of the tank had stirred up with running it the other day, more draining on the cards I think as what's coming up the pipe looks and smells a little "off" Rolling Eyes

Probably still some debris in the fuel slines or filters.Mine had stood fifteen years and in the end I had to strip and clean out the whole system.

I know it's too late now but I have got hold of some repair kits for the mechanical pumps.If anyone has an old one they don't want anymore I'd happily buy it to recondition and keep as a spare.
