1988 YAMAHA RZR250 with 350 top end, fuel tap

[rzsteve]

Hi, can anyone please help? My bike had to be converted from the standard RZR250 carbs which have a vacuum tap to 31k 350 carbs which dont have a vacuum, will a later YPVS fuel tap fit the RZR tank? Approx measurements are centre of screw hole to other screw hole is 35mm, looking down from the reserve and fuel feed the unit is 55mm long and 20mm wide (the part that bolts to the tank). I would appreciate any advice and thanks in advance.

all my 31k had vacuum pipe on the carb, on the left side of the right carb

I've got my original RZR fuel tank, with tap and an F2 tank, with tap, both taps look exactly the same.
The Yambits part numbers (FTT008) are the same for the RZR and the F2.

Thanks guys, will have a closer look. The seller told me they were 31k carbs, do all YPVS carbs have a vacuum then? If so, dont know what I have on the bike!
