what i mean buy goes out is it stops pumpin fuel, i can take the line off the carb side of pump turn it over no fuel sprays out. and my other 620 was sittin in a collection for years, looks like show room new. but last time i took it out for drive it started to sputter a little but it was on almost empty tank when happen, it my have bad gas settled in bottom, it was running fine and i assued the guy had drain it but maybe not, it has a og nikki pump. that way i think settlement is blockin pickup on low tank. also the place that cleaned the tank, though that i should remove the strianer inside the tank and add an extra in line filter. but i wasnt sure bout that idea so i didnt remove it, what u guys think?

my 620 keeps killing fuel pumps, first time i just replaced the pump. couple days later it went out again, replaced it again under warrenty. i was thinkin just a bad part, but couple days later went out again. so the third time i pull tank took it and had it cleaned had a little trash in it but no rust so i didnt pay the extra money to have it red coated because there was no rust. while the tank was getting cleaned, i cleaned the hard lines with carb cleaner and blowed them out very good with air. replaced all hose's and filter, even cleand the return line. everything seem good to go, got tank back put on hook everything up put in some good top grade gas. and it went out again took a little longer this time maybe bout week r two. i have no mech. expirence but i think something this miner i could do, what am i donig wrong. any advise i would be greatful thanks also got another 620 thats starting to sputter a little to, could the enthol gas be eatting the pump up.

haven't bought one yet, doning little research first. the one that looks like the L, i read in wiki that it came in the bluebird and vanette and that it would bolt right to 620 mount. that it would been better choice than sd22 because of that?

can anyone tell me if the ld20t will mount up on the stock mounts. i have heard this is true but wanted to confirm.
