742/743 Do I need 2 fuel filters?

[onepoket]

I have a 742 that has a reman Kubota v1702 in it. I just bought it about 2 weeks ago and Ive been going through fixing leaks and doing general maintenance. I noticed that there appears to be the inline fuel filter that was on the 742 still in place as well as the right side frame mounted fuel filter that is on the 743. Can I safely remove the inline filter? And if not does the entire filter just get replaced or is there an element inside that gets replaced? Thanks for any info. This is my first post, but I've been reading a ton of info on here as I have some drive issues as well, but I'll leave those for another time for now. -onepoket

They generally only have the single CAV style filter mounted to the frame, but people put the inline ones for that extra bit of filtering. No reason why you can't take it out.

Tazza, Thanks for the reply. So, as it turns out what I thought was an inline filter is actually a fuel pump. I couldn't tell because the mounting piece covered any labels. I was attempting to remove the "inline filter" since I was replacing the frame mounted one anyway. So, I took it out and it had a E8135 on it, searching the internet for "E8135 fuel" brought up a fuel pump. So, my new question is, do I need this pump? I thought the pump was on the engine itself am I wrong? Is this a holdover piece from when it had the Ford gasoline engine in it? I'm at a loss now, I can't start the thing anyway, not sure if its a battery thing yet or not, it cranks once or twice but won't turn over, then there seems to be not enough juice to try again. Could the pump be causing problems with the engine starting? Thanks for any info. PS Sorry for the lack of formatting, I tried switching on the HTML editor but it does not allow me to type into the field so this is the only way that works.

the Kubota 1702 has a mech. fuel pump on the engine, and a primer bulb near the frame based fuel filter. I have seen electric fuel pumps also added. If it were me I would take out the primer bulb put in a electric pump there, go to the filter ( and relocate it towards the back )and disconnect the mech. pump .

I have had machines with electric pumps fitted before too, not sure why but they were there. Great for if you run the machine dry often, saves effort priming the system by hand.
I have never had issues with mechanical pumps, but yours may be bad, that's why they installed the electric one?

Yeah, not sure if the mechanical one is bad, how would I test it? My thinking was the electric pump was in there as a holdover from when the machine went from the Ford gas engine to a reman v1702 Kubota. Maybe they just left it in the loop. I do not have a primer ball so it did come in handy after changing the fuel filter.

Oh and my starting issue turned out to be a bad battery. Surprised by that because the guy I got it from replaced it about a year ago. Anyway, easy fix.

It is possible that it was used for the petrol engine and just not removed, it shouldn't casue any harm.
Glad you sorked out the starting issue, batteries just don't last as long as they used to.
