Thread: VN fuel pump

Just have to change the connection plug over, you will have to remove the Landy pump from the cradle and fit the VN pump in it's place, easy, Regards Frank.

Standard shrink tube won't stand up to petrol after a while - I used insulation from 240v wire and small tie wraps.

the plug 'kit' is available as a 'fuel miser' part. the wires don't solder together well at times depending on their condition, if they look dark instead of bright copper when you strip them back then don't bother trying to join them with solder, a GOOD crimp join will suffice as they aren't under any duress.


use proper submersible efi rubber hose too, or it will break down over time and fall to bits

I've done quite a few pump replacements using the Bosch pump kit (BFP772) for the VN. It contains a replacement pump connector cable. Ordinary crimp joiners suffice to make the connections. It is possible to reuse the original LR plastic pressure hose but it is quite an effort to get it off the old pump without wrecking it. Once off a regular hose clamp will hold it on the new pump. If you do wreck it you will need a chunk of submersible EFI hose, generally around $30 a foot.

Hi , thanks for the replys, I've ordered the Bosch pump. As I trying to be a step ahead of murphy when I do the job, trying to get submersible EFI fuel line is not working either no one in Albany has heard of it or if they have, don't carry it. So how Long does the non sub, EFI line last in the tank???. Gary

Regular EFI hose will swell up and burst within a month, not worth the risk.

One ebay seller has the proper stuff:
5/16" SUBMERSIBLE IN-TANK FUEL LINE HOSE SAE30R10 SPECS | eBay

Mackay also has some "in tank" fuel hose in their catalogue, haven't tried it yet. Also you can supposedly use PVC reinforced fuel hose, one member on here got some for his P38 from an industrial hose supplier quite cheaply. Personally I wouldn't as all the PVC fuel hose I've seen creeps out from under clamps and goes rock hard within a year or two.

Hi thanks for all the help so far, I've ordered the recommended Bosch pump, but curious whether the replacement non genuin Bosch pump could have been used???
My neighbour is a marine mechanic, and has silicon fuel line that they use in the tanks, would this be ok to use and using the EFI hose clamps ...thanks again. Gary

the bosch ones last a little better and so long as the hose is silicon inner and outer around the pressure web then you'll be fine.

The reason that normal EFI hose comes apart is that its only the rubber on the inside of the hose that is fuel resistant, the stuff on the outside of the webbing is just plain rubber.
