Gen 1 Fuel Filter Mod & Pump Replacement

Grab a foot of this too.
 
I see your starter relay mounting position is changed, why?
Man those steel subframes look ugly, I’m used to seeing my aluminium subframe lol, that subframe you have looks unusual.. what’s going on there?
Don’t know anything about the starter relay, unless that is what the main positive wire is connected to. If that’s it then it was moved when I put the gsxr1000 tail on. The busa subframe had to be modified to adapt the Other

got the tail reassembled this morning and got a shot of the inside of the tank. Also replaced the vent hoses on back of the tank and drilled the bypass hole out to 1/4. As an added bonus I found out that the pump is out for delivery a day early

Aaaaaaaahh, yes, of course! The pieces are falling into place now lol.
I'd forgotten all about your GSXR1000 tail end . . that's why the starter relay is repositioned and the subframe looked weird.
Duhhhhhh. Mystery solved!
Bike's looking good mate . . she'll be a rocketship next time you take her for a spin, with that fuel system all sorted!
 
To quote Isoroku Yamamoto. :I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve.

Is perfect as the giant is awake and that throttle response is pissed off!!! Lol

I will need to have it tuned on the quick as my wb reads 10.8-11.4 afr cruising around. A lol too rich for my taste. Now on to pictures so that someone here who shall remain nameless will give me my damn pie back! ;)

I drilled holes in the terminals to run wire through then soldered

So basically the whole reason for the modification is to have the ability to change the real filter without replacing the entire enclosed unit. X<$200 and some time vs $600+ for a drop in replacement.
Speaking of which...
@SSGT_Bwhere is your filter located now and how did you make the injector tester-cleaner connection?

Absolutely necessary if you plan on keeping the bike more than 10,000 miles IMO!

@SSGT_B how did you make the injector tester-cleaner connection?

i used a pice of rubber hose that fit over the injector. A 1/2 pvc cap from my sprinkler system. Glued cap over one end of hose. Drilled a hole in the cap and glued the spray nozzle into the cap. Used a clamp on the hose to hold it on injector. For power I used a 9v battery with a power lead I made from scrap projects. Honestly about 1.50 worth of materials I had laying around. I can take better pics of it for you tomorrow if you like

I could tell the wiring and pvc cap, but I wasn't sure how you connected it to the fuel injector. Easy peasy!

So it doesn’t float free in the fuel, it’s enclosed? There has to be more to the fuel filter than that though right? Never had one out on the bench.
It is completely surrounded in fuel. its in the lowest possible point the fuel can be in the tank - in the very bottom on the "pump assembly" - that bulge that protrudes out of the bottom of the tank - its in there.

after that the fuel then goes through the actual filter in the upper part of the assembly (the one we drill) before being fed to the injectors.
