I need to install a fuel filter between the fuel cell and BG280 fuel pump. Is a 40 micron filter to fine? I'm using VP 110 race gas will a filter that says gas only work with this type of fuel? Should I stay away from paper type elements

I ran a paper element with race gas for years with uot issue. I think the only time you "NEED" a SS one is when running alky.

I use a brass screen type filter to get any of the
larger items then then the finer filter after the pump,
pumps dont like to suck so dont add any restriction

Thanks. How about the Micron size?

Call Barry Grant and ask them what size to use in front of the pump. There (BG) paper element fiters are 10 micron, way to small for most electric pumps according to Magnafuel I switch from the BG 500 filter to a 100 micron in line and my AFR went richer at WOT

I run a system 1 with a 30 micron between the tank and pump with no problems.

Plenty of flow
