Gen2 fuel pump & fuel filter replacement for dummi

I attached the ground lead using a large worm type clamp. In my understanding, this ground lead is for static charge - possibly not needed at all.

I also attached the ground lead with a stainless jubilee type clip.  Seems all good.

Never heard of one igniting due to static buildup so perhaps not needed?

ok just to follow up, seems like the pump from fuelperformance works fine, and the filter from demon tweaks works fine as well.

I didn't use Jubilee, I used "fuel injection" clamps from Halfords, which are more seamless than Jubilee, but not as great as the Otiker (sp) clamps. Does anyone have any top tips for just how tight to make those clamps on the various fuel hoses in the fuel pump assembly? Additionally I was wondering if there is any ideas on how to mitagate these hoses from coming undone in addition to the clamps.  If you could lets say "wire" the fuel filter to the base so that it can never move beyond the length of hose between the filter and base, even if a clamp came loose it wouldnt be able to move enough for the hose to pop off....etc...any ideas?

This happened to me mate about 1000 miles after replacing my hose that was split. I used the oetiker clamps and theý were on tight but it still came off.

I think it was down to the fuel softening the hose which made it pop off. When I put the clamps on again I doubled some of them up where I could fit them on and had no bother since.

You tighten them beyond what seems reasonable, it goes in the tank and after a few heat cycles probably need to be tightened up a bit more once things grow/shrink/soften. The hose I'm using inside my tank is supposed to be fuel proof, I didn't check to see via some printed numbers if it was.   This entire design seems half assed, I wish they would just have done some molded mount w/gromet the fuel filter attaches to the plate with instead of this tiny piece of hose with 2 clamps.

Sorry should have explained that better. It was the big hose that had popped off, not the little piece. So I used 4 clamps instead of 2 just to make sure it wasn't going to come off again. I'll be taking my tank off the bike shortly anyway so I'll double check.

I used submersible fuel line aswell but don't think it takes much to blow the hose off once it's slightly loose or softened up.

The genuine hose is hard to come by,plenty of sources sell ' in tank fuel hose' but it's not the real deal.

The thicker the wall thickness the softer and more pliable it gets when submerged,so a clamp that is tight enough when new could soon go soft after a few months and relieve some of the clamping pressure


I think BMW do a kit of hoses,filter and clamps that will swap into our bikes for a very reasonable price

AF1 Racing has been selling this: http://www.af1racing.com/store/Scripts/prodView.asp?idProduct=6565

ok, well my problem was the clamp at the very end of the line...final clamp fuel pump hose into mounting plate.  Looks like maybe I didn't put the clamp far enough toward the base plate. All the other clamps look fine.  So 2nd try hopefully will be ok.  Getting pretty quick at doing this job though!!!!

AF1 does seem to have it all, minus the actual fuel pump itself.  Which is a generic item, mine is from FP but I'm sure it's the same as at least a dozen other uses.

Nope,I'm talking about genuine BM parts from the dealer

I found the info on AF1 I think when I researched it for my bike

I can't remember what model it was for but I think it was for one of the newer boxer twins,not sure though

It was for the U shaped corrugated pipe.,new fuel filter and short final pipe with all clips (and they weren't worm drive type)

Guaranteed to be the real deal for in tank use ( well as much as increased Ethanol allows) they listed part numbers and it was a very reasonable price given their reputation for quality

I would have gone down that route but I had a nearly new new pump /filter assy to hand anyway so I just bought a length of the proper spec Cohline R10 fuel tube/a handful of oetiker clamps and fitted that.

Well actually I reused the OEM spring clamps in the end

Never had any issues since so hopefully that sorted the issue of the lower hose disintegrating in the fuel
