Hi all i was hoping for some help i have a basket case 88 fj1200 that i bought for pennys was running although quite rough i have sent the carbs out to be cleaned but i want to revert the fueling back to standard as someone had converted it to a gravity feed tank. Ihave already bought a pump petcock fuelfilter and most of the fuel lines but was wondering what size fuel line do i need going from the pump to petcock as you can no longer get it new aslo what size clips for it
The fuel pump models have a smaller needle and seat, you will need to replace those with the correct sets for the fuel pump model. The Yamaha part number listed is 3CF-14107-15-00 but you should be able to find them cheaper elsewhere such as http://www.rpmracingca.com/proddetail.asp?prod=3CF-14107-15 (http://www.rpmracingca.com/proddetail.asp?prod=3CF-14107-15)
I recently added a fuel pump to my 89 and I used 5/16 (~8mm) fuel line because its what I had laying around and it seems to work just fine.
Out of curiosity, what fuel pump did you go with?
Thanks for the reply melloncollie i have bought a used fj1200 pump from ebay only because it came with the mounting bracket what size clamps do i need for 5/16
5/16?
The bike is metric. Gravity fuel lines are 10mm and pumped (I think) is 6mm. That is internal diameter. The line(s) may have a different wall thickness. So pick a clamp that will compress the line you have.
I used all 1/4" lines on my '89.
1/4 inch X 25.4 = 6.35mm. Seems legit...
Don't forget to check your float needles: https://fjowners.com/index.php?topic=9836.0
I had not realised the needle and seat would be different thank's for that in advance
Don't forget, RPM is the only place you can still get the genuine Yamaha fuel pump.
Once these are gone, there are no more...
