should a fuel filter fill right up?
Hi,
I had an issue with my r1 fuel pump not priming, it would tick away but never shut up. I removed a few hoses eariler today at pump end and carb end,
reconnected them after knowing fuel was getting through and low and behoild the dam thing primes!
"WOOHOO" i thought (and jumped straight in to start it, forgetting it was in gear and nearly went through the garage door...)
So then I decided it was time to fit a fuel filter. Now there isn't space to fit it between the tank and the pump, so I fitted it after the
pump.
After sorting a few leaks from poorly tightened hoses clips I flicked the ignition to see if the pump would still prime.
Fuel poured into the see through filter to about half way, then the pump stopped clicking or priming and went quiet.
Now I thought it was meant to fill the filter right up?
SVA is a week today and I want to make sure I have a car that can be tested and not thrown off the site!

are you running an injected system? is it a high pressure or a low pressure filter?

if the inlet and outlett are top an bottom then i'd expect it to fill right up, up they're on the sides, then i'd expect half way.
but i guess it dependeds on the shape of the filter etc.

its not vertical, nor is it horizontal, its at about 45 degrees.
its this item
http://www.cbsonline.co.uk/fuel-filter-nylon-ffny-345-p.asp
but it doesn;t look quite the same as that, but it was definatly that item I ordered. I mean its similar, but slightly different.

Hi,
Its running carbs, not sure about the filter, see link in earlier post to the actual filter I bought.

i have a low pressure filter that looks like that betweem my tank, and my pump. when primed it only fills up about 1/2 to 2/3 of the filter. mine is
fitted horizontally.

I dont think it will fill then, basically your pump is creating flow through the system but its not heavily pressuring the whole thing with fuel. I
wouldn't be worried if it was filling halfway.

thanks guys. I just need to get the car on its wheels so I can rock it back and forth to get neutral... then I can try and start it again!

I had a similar problem with a fuel filter on the out let of my swirl pot....It would trap air. As I'm running fuel injection I figured any air
in the system is not good, so I changed the position to between the tank and the lifter pump...From here it seems to fill....

if its at 45 degrees, you'll get an air lock in there as the outlet is below the bubble, but as long as everything runs properly, it
shouldn't be a problem

ehem don't you think it would be a good idea to have the starter only work in neutral as on the bike?

I've got my filter mounted vertically between tank and pump (to protect the pump from debris - highly recommended if you can find some space)
and it certainly fills up completely but it only did this after running for a while. Initially I had an air bubble but after driving it the bubble
disappeared. I think the bubble gets broken up by vibration and bits of the bubble get passed through eventually leaving no bubble.
Either way it shouldn't be a problem as long as the pressure is correct it will either purge air or pass fuel and your float chamber will fill
with fuel or pass air accordingly.
Cheers,
Craig.

How many cars with manual gearboxes have you driven with this feature?

No. Otherwise if you stall it in first you have to try and get it into neutral before starting. On my BEC I just put down the clutch, start the engine
and off we go (ie I disabled the neutral start feature).
