Been covered previous in this forum, two grades of "rubber" fuel lines, one internal and external layers of fuel resistant grade hose and another whose which is not fuel rated as immersed in fuel, on the outer layer, cost the indicator. The later which causes degraded internal to tank fuel line problems.
Worked on many bikes and cars with internal to tank fuel pumps, and filters. The well known Suzuki TL and TL1000R fuel tank access panel leak a particular difficult design fault to mitigate. Worse the internal fuel filter was bespoke, moved an all metal fuel filter to external access, straight forward to replumb the internal hoses and metal fuel lines. External pump will have significant modifications most probable. Less drama to use a best that can be bought generic pump like a 007 series and expect many years trouble free operation internal, external filter however is a worthwhile modification. Include a piccy later, 7C outside this morning...brrrr
As a guide for what it is worth, few pumps are manufacturer specific, a general purpose "007" style pump can be substituted, two variations, plug and screw terminal, the latter required for tight spaced "pump/filter" towers internal to the tank. 3 bar pressure is usually sufficient, on cars and motorcycles of the era. Can actually rebuild sealed pumps, which have done several times, still running on a gixxer 1000. HTH j
*** oh and internal to most FI systems is a mechanical pressure limiter which yields the actual 3 bar/42psi output to external items, many pumps will pump to 90psi, measured here on the bench, when run without the pressure regulator, small circular metal part of the FI tower assembly.
