Hopefully my pump photos will appear.
I now have 10 pumps languishing in a box due to having broken ‘spigot’ ends ( wrong term?)
I repair heaters as a bit of a hobby and get them in all sorts of conditions.
A common problem occurs when there is corrosion where the outlet pipe joins the nut, the pipe simply breaks off from the nut.
I don’t think that Eberspacher do spares for this end of the pump ( they do have them for the pump to tank side to accomodate different supply pipes)
Just wondered if anyone had any ideas about replacing these? possibly they are used in other fuel pumps.

Cheers.
 
Would it not be possible to drill into the nut to fit the pipe, then silver solder/braze it in place?
 
It is a perenial problem, but fortunately not on boats, it is always due to the pump being externally mounted (as it should be) on the underside of a vehicle and exposed to spray. There may well be a small female hosetail available from suppliers like BES if you identify the thread. Actually now I think about it I'm not sure they are not available as a part, I think I have some old 24v Eber pumps left which could be canibalised, I will have a look. Soldering may not be possible as some of them were aluminium alloy i recall.
 
If it can't be soldered, could it be tapped for a threaded spigot?
Assemble with some sort of Loctite?
 
Just realised that the connector on my test rig has got a different ‘spigot’than the usual.
It has got a sort of adapter on it, its wider than the normal type and incorporates a ‘compression end’ so it can fit over the fuel pipe. This may be a sort of british/inland waterways spec so it can fit direct to a copper pipe without a rubber connector.
I will try a bit of searching around and report back!!

There were a few anomalies in fuel pump connections for a while until the BSS finally realised that 7840 hose rubber was perfectly OK and approved it, but that was for a short time. Webasto even produced a complete enclosure to get round the problem, but as I say, it was for a very short time. Not surprisingly, a number of small parts are not listed and unavailable unless you are a full service dealer, often then only in quantity.
 
Yes David. Just searching the canal boaters forums. They have or had all sorts of problems passing inspections, current issue is that when they join pipe with rubber the BSS date has to be visable on each connection which can be hard to acheive. Some solutions seem to be to present a length of the pipe with the BSS mark on and the invoice!!

Even BSS inspectors rarely know what is acceptable to the BSS office on a heating system I can give a manufacturers confirmation to the owner stating the hose complies, that satisfies the BSS office. The thing most inspectors miss because they don't remove the hose to check is that each copper pipe connected by a rubber hhose shoud have a formed nipple on the end, plain tube is not allowed, something I quite agree with.

Different brass tails are used in the welding industry which look like they could be adapted,used for different welding gases.
