Tank looking amazing - but I’m still having some major problems with leaking from the fuel pump baseplate!!

Gotta work on it some more when I get a spare moment!

I’m at a loss at the moment!

Base plate looks nice and flat.. The specified Loctite 518 was used and has oozed out as the pump was bolted down - a nice bead of sealant showing all the way around.

Despite this there’s a constant drip drip drip off one of the front bolts.
I’m a little concerned about the length of the bolts - the original are no longer long enough and the ones Rich sent me only just bite and one of them doesn’t torque up and feels like a stripped fastener (not the one where the leak is evident).
I’m sure it’s not stripped as I got nowhere near the specified torque setting of 7nm... I recon this is just because the bolt is only just reaching the threads.
I’ve ordered a set of bolts, 5mm longer and will see if that enables me to torque all of the fasteners down to spec.

If that doesn’t work - I’m at a total loss

Thought about making an additional gasket out of fuel gasket paper. If that doesn’t work I have a very pretty and expensive paper weight!

Odd that it's doing that. Sadly have to strip the pump out and see what's going on.

Best of luck though I can imagine it's a more than little frustrating.

Ta - but don’t want to resort to bodging it by sealing with tons of goo just yet!

Gonna do all I can to sort it before I bother Richard - and there’s not much he could do unless I ship it back to him - pump and all. I’d like to avoid having to do that if I can.

If you have the original Gasket I can cut one  for you in a thicker material using it as a template . ( when I am in the UK .)  -  I have a stock off  various thicknesses in the back of the garage for such occasions.
I am guessing that you fitted a new gasket when you transferred the pump to the new fuel tank ?
 

Petro-Chem Grade NACF  Materials
It  will  give a better compression fitting between the base of the tank and pump plate .

Zax, thanks for the kind offer... there is no gasket between the tank and the pump unit base plate. It relies on a big O ring that sits in a recess all the way round the perimeter to make the seal.

My thought was to make an additional gasket to sit outside the o ring to supplement it.

As it is I’m just leak testing my latest attempt at making a seal off the bike...
Gave everything a forensic level clean and used copious quantities of Loctite 518. So far with about a litre of fuel - no leaks!!

The longer bolts are too long and ‘bottom out’ so I’m going with what Richard supplied - the one that feels stripped, I have gone without a washer to get more of the thread in play. This is allowing me to nip it up to my satisfaction - but I daren’t put 7nm torque to it. The rest are all good.

Use the longer bolts and put extra washers so you can play around with the length, you want to use as much thread as possible preferably so the pump tightens down just before the bolt bottoms out.

Hi Richard, you have some advertizing malware on your OS

Download Malwarebytes free for pc, Mac or android.

http://www.malwarebytes.com/

Run it and it will clear that up for you.

Tanks look stunning. Any news on gen 1/gen 2 tanks yet?
Question everything.
