New fuel pump on a DG engine

[elsid]

A few days ago my 1985 Autosleeper with DG engine would not start. On checking I found that fuel was not getting to the carb. I removed the carb and tried it out on the bench, it would not lift fuel from a can next to it on the bench and even after priming it would only pump a feeble amount. I 'phoned around the local suppliers and was told by two of them that their catalogues only listed electric pumps for the 1982 to 1990 DG engine, one offered a Pierburgh at £89.85 + vat + £6 delivery, one offered a pump that would fit but had the inlet and outlet in the wrong place for £40 + vat and Bridgwater VW had a new pump for £58.85 inc vat. I ordered the pump from VW and it arrived the following day, it is a Pierburgh which is the same as the original except the inlet is 8mm instead of 6mm. I had to make up an 8mm to 6mm adaptor to fit the inlet pipe to the pump. After fitting it the engine would not start before the battery was nearly flat, it was not enough to lift the fuel from the tank. I recharged the battery and fitted a short piece of tube to the inlet of the pump and ran it to a can of petrol, the engine started straight away. I ran it for a short while and then refitted the inlet pipe to the pump and restarted it. It is now running OK, touch wood!!

ps, check your fuel pump actuator rod is the correct length or you may not have solved your problem.......

elsid, should have gone to Spec.................. I mean JK or GSF.

First off.. the one GSF sells doesnt fit... so dont bother with that..

Second off.. have you checked the fuel filter as the new pump ought to pull the fuel up pretty quickly.. fuel filter should be a large one, not the crappy small ones that GSF sell...

Having been transported home by RAC yesterday,I got one from GSF and fitted it to my DG this morning (before I read this post). The bloke at GSF said they had some problems with the one they used to stock. The inlet pipe is in a different position but I could still connect the fuel line around the vent, also the diameter is bigger but I got over that with a new lenght of 7mm fuel line from the filter.
Next job is to replace the rest of the fuel lines as they are looking tired - I'll follow Oldjets earlier posting for this
