fuel pump rebuild kit.


Recommended Posts

Need to rebuild my fuel pump (Four Pot) have a 'County Kit' must have had for several years, and up to now unused.

 

looks the same as the current Moss offering, think this safe to use with latest petrol?

 

Or is there a better way to go?

 

Cheers,

 

John.

Alec's right on regarding the work of Dave Davies. First class, and definitely the way to go.

 

There are a number of posts here on the subject, including at least one where I've uploaded photos of Dave's work on one of my fuel pumps. (Traveling now and not able to access the link myself.)

If the kit dates to a time when methanol was not present in petrol to any significant level, the material of the diaphragm and other "rubbery" bits in your kit might not take kindly to the current liquid offerings!

Thanks for the replies guys.

 

Ian, that was really my question with the kit I've had a while,

guess silly really to use it, and have to do the job again

relatively quickly, so presumably the kits available now are

'Modern Petrol safe?'

 

Alec/Don, Easy to contact your recommendation, and have the job done, but

I started 'Playing ' with old bangers best part of 60 years ago, because it was the only way to keep my dads car/van

on the road. Those were my formative years, and I still 'Play' with old cars because of those fun days, when to fix something

was a very satisfying big deal.

Sure many will empathise with this, so as rebuilding a fuel pump is pretty straight forward that's likely .the way I'll go.

 

My spare is on the car and belting away merrily, so I'll probobly do the job over the winter with a 'New' kit

 

But thanks for the replies.

 

Cheers,

I too have employed Dave Davies services with an excellent result for very good value. He has access to a supply of the 'top hat' seal which fits between the membrane plunger and the pump body. I have yet to see included one of these in a repair kit. Like eveything in synthetic rubber they become brittle withe the years and leak.

John,

I can't say whether the kits available now are methanol-safe, so ask the suppliers.

Like you, I do the jobs on my car unless they require specialist skills &/or tools, such as axle rebuild by Pete Cox (but I take the axle out and put it back in). The fuel pump is a simple device and I did the replacement of diaphragm and valves myself 19 years ago - still going well!

Here's a photo of the ethanol-safe fuel pump diaphragm from the current kit sold by TRF against the original from the 1960s in my car. This diaphragm, made by Effbe, is fine.

 

One of the kits with modern seals and diaphragms would be a fine DIY project, John.

 

Just don't waste your time on old rubber. It'll mean redoing it before long anyway and possibly a stranding in the process.

TRF includes that top-hat plunger seal in their kit, James, but I dunno if anyone on your side does.

 

Dave includes his own additional seal between block and pump housing, as shown in pix in the previous thread.

Like John,

 

I'd prefer to rebuild my own pump in an ideal world . . . . . not that difficult after all.

 

I once needed one in a hurry, hence used Dave - apart from the essential extra unobtainium seal, next day turnaround, the job was just so bloody good that I'd simply not have got near it. For £50 job done to perfection, as opposed to a less good rebuild kit and my time, it was a no-brainer. I've used him ever since. Top man, and we always have an enjoyable phone natter catching up - even though we've never met in person.

 

By the way, he's also the best bearing supplier I've come across for pukka OE new old stock of all descriptions - that's his mainstream business, pumps are just an add-on.

 

Cheers

So does anybody know if the rebuild kits are all now

'Modern Fuel Safe?

 

Dons very helpful phot shows a branded red diaphragm,

All kits available over here show an unbranded one?

 

So has anyone got two or three years use out of one of these kits?

 

Cheers,

 

John.

I used a kit from Australia and it included the all important seal. Mine has so far lasted about 5 years with no ill effects from modern fuels.

 

(which means it will probably fail tomorrow!)

I had Dave do mine 3 years ago and I supplied him with that red diaphragm that I got from The Road Factory as my one just disintegrated while in France. I put that down to the E10 fuel I put in, and that TRF one is guaranteed against the E10, Needless to say, still going fine although I do seek out E5 where I can in France.

10 out of 10 for Dave´s work ,and a gent too!
