Fuel pump?

Big lumps of metals and spanners. Including servicing and fluids.

Fuel pump?

Post by Dubworth »

Hello, been having some intermittent fun with my 1985 DF recently. Occasionally it won’t start without fuel or spray start added directly to the carb. Once it it’s running however, it is flawless. Currently on holiday around Norfolk, the van drive great fit for hours, my wife then filled it up with petrol, it started a bit choppy and ran a bit rough before resuming normal service. Later on, it refused to start without some spray start.
I’ve recently serviced the van with oil, filters, plugs and a new dizzy cap. It has brickworks fuel lines that are approximately two years old. Fuel filter looks ok but I’ll be changing that as soon as possible to be safe.
I’m just wondering if this may be my fuel pump starting to weaken? Any help/advice welcomed :)

Could be. Worth taking it off and checking the pushrod for wear. It should be 100mm in length, easy and cheap to replace. You can then manually check your pump is working and repack with grease. Also check your fuel lines to see if you have any pinholes or loose connections.
Funnily enough i have a fairly new pump and pushrod fitted but in the recent very hot weather if i haven’t used it for a few days it takes a good 5 seconds to fire up whereas it has always fired up straight away. Once going it is fine.

Thanks :) I’ve ordered a push rod, some gaskets and a spacer from brickwerks. Would I be better with a high temp grease or white lithium do you think? I have both.
