Hi Marco, thanks for the video. Wondering what is the absolute simplest way to wire these valves to one toggle switch. Basically, how do you reverse position on the valves? Cheers buddy

Hi! Thank you for the video. I own a C500 Y55 D with a perkins 4.203U on it, a 70’S model. Unfortunately the clutch master cylinder is missing, there is only the triangle flange there. Could you please inform me about the size of the bore for the clutch/brake master cylinder in inches so i can get the right one. Thank you in advance for your assistance. Kind regards. Mariangelo.

Hey Marco. So with the original 1terminal 6 port my left tank was not working and only my right. Then I set it up like this and now my right tank is not working and my left one is🤦🏾‍♂️ any idea why? When left tank is selected the valves have power. When right is selected there is no power which I thought was correct

Nice Baja, I had to subscribe! like yourself I pull a toad behind my converted bus. I have a subaru Outback XT I really want a baja though lol have any experience with a swapped Subaru 2.5 turbo?

Marco,i had a question , im working on a 90s model Clark lift that has that master cylinder with two caps on top,that sucker was high dollar and super hard to find and i pride myself on finding hard to locate parts, one of the caps on top has threads where the hose that goes to the reservoir hooks up to,my question is, because the fluid lines are connected to the bottom of the master cylinder instead of on the side like 90% of most master cylinders, bench bleeding this thing is not gonna happen, what are my options? just put some fluid in it and cycle it a bit or not even cycle it ? once i put fluid in it is gonna run out the bottom once i try to install the lines getting fluid everywhere. On a normal cylinder with fittings on the side as you well know you just get a bench bleeding kit and so forth and everything is cool , once you disconnect the bleeding kit and the lines are right there you just hook them up ad you might loose a bit of fluid but not much, should i still try and bench bleed it? thank you for your time!

I understand what you're saying and I agree. But there's some people like myself bet are confident enough to reroute all of those fuel lines do they make sense. Either you're smarter than you think or I'm dumber than I think. You did a nice job

THANKS FOR VIDEO!!

Hey my friend where did you get motor again and how much if you don’t mind?

I understand that only diesels had the fuel selector switch, I ask because I have a 5.8 gas motor and having issues with my rear tank

So I have not messed with the wiring at all, so all I have to do is splice and split the wires for both the FV1 valves and run the fuel lines correctly will it work? Also will it work with the same tank selector switch inside the cab??

I'm curious how these valves have held up. I have thought about using them on 2 tank veggie oil conversions, but these aren't rated to be mounted before the pump. Or maybe it was after the pump 🤷🏻‍♂️ anyway, I hope it works for you.

Genius… I’ve been scratching my head trying to find a better more reliable solution for my RV. Thanks for taking the time to post:

I think you could skip the return line switch by just using fittings for the return line I don't think it needs to be switched.

when the selector valve fails add another filter so you have a filter from each tank before the selector valve they dont like even finest of silt rust or water from the tanks it kills them fairly quick. hope that helps

to stop the problem happening install a good fuel and water separator for each tank before the valve them cheap metal filters dont filter good enough and the 2nd problem is water we had 8 work truck 2 a yr seem to always have problems and after pissing with them for yrs we put water and fuel filter 4 to 6 micron wix filters and after my 13 or so more yrs there only one selectors froze up and one the motor on it burned up and they can be taken apart and cleaned easily take it apart and work the plungers up and dow to free them and there good as new. hope that helps someone to save some money

These tanks when not working properly are such a pita I was planning on just ordering a 32gallon fuel cell.

Yeah I can't put something like that on my off-road rig though too much stuff to get caught

pure genius my friend

Is this setup still working? The 6 port Pollak valve "seems" like a good solution, but they are all plastic, made in China parts now. Not that they were all that reliable way back when they were invented anyway...

Where do you buy those at? Autozone? I tried to google that unit code you say but google brings up all sorts of random parts with that number like computer chips, pumps, motors.

With rockauto having a lifetime replacement for under $80, granted it is a Dorman. Why did you go this way?

where did you buy the valves ??

Same here, got a diesel & having issues as well. My plan is having the rear tank feed the front tank. Or have the positive line feed the return on the front tank with a 2nd fuel pump. If it doesn’t work I too have the manual valve I can throw in & have the lines go into a box in the bed & every time I need to switch tanks I reach back there & turn both valves. What I’m thinking abt doing is having the positive line pull fuel from the back tank & the return is the front tank, then watch for the gauge to stop, then switch to the front. There’s multiple ways of doing this. I’m stuck on the rear tank rn & I only get 10 gallons.

Does this work if they’re one pump in each tank?

Can you show how you wired those two new pumps to the truck please?

Marco I am having issues with this...could you possibly help?

dude your asking to blow up!

hey, I am about to attempt this with a 1994 f250. I assume they're going to know when I say I need a toggle switch. The biggest issue I'm going to have is the wiring part.I would like to be able to try to contact you when I get to that to save me a headache

Hello, well done and thanks for sharing your experience as there is not that much information on Clark C500 models here. Does your C500 got a side shifter? Mine is a C500 Y40 PD, which has the valve installed but no control linkages and lines from the valve to a connector at the front. Regards Heinz

Who did you email for wiring diagram? Do you still have it?

Did you have a problem of one tank over filling another tank? Without the switch?

Gr8 vid

If so...do u have the electric pedal from the cobalt

This is an 2.0 LSJ ECOTEC

what would help is to know what brand, model and year of the truck you did this on and maybe even what engine, gas, or diesel. the only thing you can tell from your video is that it's a dually of some kind so it's 3/4 ton or bigger.....

What engine? 2.0l lsj supercharged?

Nice bro...how is that engine handling

You certainly helped me Thank you

Marco, do those new FSV1 selector valves still work? ill be picking one up. how did you wire up your switch to the selector? im having trouble trying to figure out how those FSV1 selectors operate, does the toggle switch reverse polarity of selector to open each port? is one port always open? or is it a selective valve? please respond soon marco, greatly would appreciate. -James

What cv's and CV angle did you end up with?

Thanks for all your help Marcos✊

How much do they cost we're all three parts

Marco, watta bout the fuel gauge in the dash?. Does it still reads seperatly how much fuel each tank has correspinding to the actual tank you are using at that momment????..

My 82’ Chevy k10 doesn’t have a fuel selector valve and not sure how to wire the button switch either

Thanks for explaining everything and showing it up close. Good work!

Yes I'm available for anybody that needs more help on this I live in El Cajon California number is area code six one nine 971 7833

I have the axles but I need the 930CV no money for the project right now getting ready for the holidays taking the Jeep out to the desert thanks for the question subscribe so you can see the progress hit the bell for the new videos

I would have done the same thing gotta sacrifice one thing for another sometimes.. are you going to run that trans with that motor?

that looks great man nice work. did you get your axles in ?

I have been trying for years to sort out that problem. I have been finding used single pin valves but they have gotten hard to find. Great idea!!
