Phoned up Riders of Bristol for an oil filter, they were happy to send me one but as I was passing Bridgewater last week I picked up one of the above from their partner shop, they said its the only one they stock for tubers/sportsers. Fitted it, not started it yet, read on google that it needs higher pump pressure. Should I be happy to use it, Harley reckon its better as its a premium type

Interestingly I currently use a 63812-90 which is longer but, IIRC, has the same 'mesh' size as yours, but has a larger surface area.

Larger surface area, would that need more or less oil pump pressure ?
If a filter needs a higher pressure does it mean higher pressure on the wearing parts of the pump? Only asking as I haven't got round to fitting the Lucky Hands pump yet.

More pressure = more load...

More surface area with the same screen size would allow more oil to flow through at any given pressure, A filter with less surface area could potentially cause an increase in load on the pump if what the pump was trying to move couldn't get through.

Would a hiflo oil filter be less wear on the pump, what about a thinner oil for winter ?

Hi,
IMO dont use the 99a filter it is made for tc motors and harleys with a much bigger pump delivery.
I have the right ones do you a swap if you want? and as for oil stick with 20/50 that meets hd spec

Do you want it right or right now ?

Cheers for the offer Tubbs, unfortunately I've fitted it already. Started but not been out for a ride yet, for an extra tenner think I'll just buy a 63805-80A or what you recommend. Salisburys not too far from me

Warming the motor before caning it is very important this weather. Mine never go WFO before 10 miles are done.
