Having a moment of doubt. Should I stick with the tried and tested 80l. Or spend a bit more (£60 as a guess) and the hassle of fitting for the 100l

Decisions decisions....

80L tank frame drops in nicely ;) And Teilo reckons he can be competitive on them :y But I'd go for the 4 hole if ordering from him. Or test the 100L single hole from the other place :-/

At the end of the day it's another 65 miles. That wouldn't be all that significant to me but YMMV. :-/

Against a (proportionately, much) more expensive tank, trickier install, no cubby holes around it and no room above it to shove bits of wood, pipe, etc. through.

If I were doing it again I would use an 80L again.

From what I remember, there isn't much difference in price between Teilo's 4 hole 80l and the other place's 100 single hole...

On the one hand, the 80l in the MV6 hasn't caused any issues with range, and I have places (currently) to fill up on route to work at 73.9p.  If I had to detour, maybe the 100l would prove more beneficial.

But then the 80l slips in so nicely, and I could probably get the tank fitted myself without bothering other people for help.  And no concerns over extra weight, higher CoG and handling.


Hmmmm

I'd go 80L if/when I do it again in a saloon and 77L(?) toroidal in an estate

You've got a single hole, I've got a 4 hole. On a single hole there's only one hole in the tank to fill, fuel feed, pressure relief and level. On a 4 hole they all have their own holes.

4 hole tanks fill quicker if you can find a high flowing pump.

Single hole tanks, or actually the multivalve, are restrictive in how much LPG they can flow

Dont think the quick filling side is going to be an issue. Do more powerful engines need a four hole then ?

I believe 4-hole is recommended for 3.0 ltrs and above due to fuel flow requirement .. especially at WOT/High RPM .... (and single hole might explain the lag some folks get ??? Although vapouriser will also have a large effect  :)  )

TB's flows enough LPG (but is approaching borderline). The Lag is present on 4 hole setups too ;)

But, after my visit there on Friday, we think we're getting somewhere. Seems to be caused by the Vaporiser. At gear change the injector times spike down (followed by the LPG times as it's a piggyback system), causing the LPG pressure to "overshoot" and cause brief flooding when the injectors open again. This is hopefully going to be fixed with the new vaporisers :y

Just out of interest, do you know if your system has a timing processor?

If I knew what one of them was I would be able to answer you !!

Write ups for my system ...
