I am going to do a service on Renzo’s TC Jubilee. It has the upward facing oil filter, rather than the later hanging oil filter. The current oil filter is a Borg & Beck BFO 4085, does anyone know the Unipart equivalent part number (GFExxx), also where I can source one as many white Unipart filters seem to have dried up on eBay.
Thanks in advance.

I run a GFE 121 on my MGB with the same inverted arrangement

When I stripped down my 1.8 I remember it said Halfords on it (I assume the chain Halfords and not just a coincidence brand, but I don't really know ) but I'm not sure on the number, I can find it out for you tonight though if it'll help

Thanks guys, I’m hoping to find a pukka white Unipart one GFE121. David where did you find yours?

I may have some GFE121 in white, I will have a look.
I have a Mann filter on mine currently. I also have some of the early black yellow ones.
Shed is due for a clear out mid next week as I need to check what I have and what I don't need.

Chris last one was a ebay special they are listed quite often as was a popular filter back in the day it also fits a Ford Pinto if memory serves me correctly that as a Motorcraft EFL90 Mahle OC23
Below is from my Mann Filter catalogue

G Thread
H Overall height
bar Bypass valve opening pressure (where present)
R Number of anti-drain back valves

Notes: ◦Unipart and Champion filters are 4" or 100mm overall height
◦Always use a filter with both bypass and anti-drainback valves
◦The specified bypass pressure for the MGB is 13-17psi, or 0.896 to 1.172bar, a filter should be selected that falls within this range.

Thanks David. Paul if you have a pukka white Unipart one that would be great.

I will have a look Chris.
I was put on to the Mann filters as Chris Wilson (Jubilee owner) found that the internal valve in these held the oil in the filter very well. Some of the Unipart filters when fitted and after sitting for a while empty and then the oil pump has to fill the filter before oil pressure is reached. Which is not good.

I find the GFE121 on my MGB holds oil well unless its not been used for 3 weeks or so. I have a ignition kill switch I use as a immobiliser I switch that in allowing me to crank it until gauge shows pressure then enable the ignition.

Always a sensible precaution regardless of non return valve effectiveness. Of course if you have a mechanical fuel pump and twin SUs this safety feature is built in due to the time it takes for it to refill the float bowls...

Spot on!

Thanks David - got a bid on it.

This site gives a different Unipart number GFE422
https://www.oilfilter-crossreference.co ... CK/BFO4085

This ebay listing says "It has the Part No. BFO4085 and is the equivalent to Unipart oil filters GFE121 & GFE422."

FYI also used on Avenger, MGB, and most 70s Fords https://webcat.borgandbeck.com/PartDeta ... nfoBFO4085
