fuel pump upgrade for 99

[Maj]

The car stuff ususlly runs at 2.5 bar pressure and bikes or late cars at 3 bar, so a bosch reg off a std ba ford etc will not work , be sure you get an adjustable one or the correct pressure , also the walbro external pumps seen on ebay work well and are smaller diameter than the vl pumps .
This would be overkill for you with the big bosch pump but shows the layout on my 08

The little Sard regulator would work well, there very temp stable, better than some of the bigger regulators that i have seen 5-7 psi pressure variation from hot to cold
