Hello. This is my first post in the forum. I purchased a FL350. My Bad. LOL
And Yes I already have a service manual.
It does not run at the moment because of old broken fuel lines and perhaps in need of a top end.
However it appears that it had once been running by using an electric fuel pump with a fuel pressure regulator attached?
The pump and regulator still works.
Is there any reason why I should not use this setup?
And if I do what setting do you think the fuel regulator should be set on. It has 1-5 on it with 1/2 marks in between. And how would you recommend plumbing the lines.
The old vacuum line that use to go the the stock pump is blocked off.
From the looks of it when I got it, this setup had been used for quite some time.
If the general opinion here on the forum says NO, then should I just go back to the standard stock setup??
And if YES to that question , what type of fuel pump?? I have seen "replacement" type pumps from different sources of FL350 part people.
They say they will work but fit a little different
That is the exact pump and set up a guy had on the first machine I bought but the yoyo forgot to block the vacuum line for the original pump. Yup you guessed it Boooooooom. You said it needs top end work and this may be one of the reasons. The problem with that set up is the pressure will over come the fuel needle in the carb and fuel will piss all over and you will also have flooding issues. Give it up and go back to the way Honda had it. Buy a pump from polaris #3085275. That's the one I use on both my machines with no issues. When buying a pump you need to do a flow test. You need to get approx. 40z in 10sec and this pump does that. On my brothers machine with a high mod
Engine it uses 10oz per min fuel (actual fuel use). As a final note here I will have to say that after you do the rebuild and it has passed the pressure and vacuum test you WILL ONLY run avgas or race fuel. I currently have nine melted pistons in my shop. The fuel we get today does not meet the min octane rating in the Honda manual and it is total crap in my opinion. We are all big boys here -- your on your own. Trust me I have experience on the fl350.
