Re: XJR Jag

No, I won't be doing any special recalls. The whole discussion here is about verifying your own work before it leaves your hands. I've outlined how I have previously checked that shutoffs do really work as a pair. I'm happy to have made my own simple changes to check them individually now; I don't h...

Re: LPG Filler Relocation - Inside Boot..... but extendable?

There is quite a collection of regulations (UK, EU) and industry codes (UKLPG) about LPG in vehicles. Some apply to propulsion fuel, some to "domestic" e.g. heat and light. Some apply to new build vehicles, some apply to type-approved retrofit kits, some apply to any other retrofit. CNG and LPG have...

Re: XJR Jag

A test that checks for snags after valve fitting and also works with pre-fitted multivalves ... simply roll the tank about and watch the pointer. There is sadly no equivalent watching or fingering action for 4-hole setups. No doubt some never use 4-holes because [insert some reason]. Simon, no-one h...

Re: lpg feed pipe size on 500 bhp engine.

You could extend the runtime a little before freezing by adding a bit of thermal mass, loop some water hoses temporarily and fill the vaps. Be sure to hook the diaphragm onto the valve lever, so that 'inflation' pulls the valve closed. The odd dinky spring is I think there to help that happen from r...

Re: XJR Jag

Fifteen years ago we'd be fitting mostly Stargas and BRC valves. Whether because of that or the splash-tinker-fillup later process, no particular issues with foam floats. I maintain that if there is going to be a snag on filling, it should happen to the installer. The generosity of the 20% don't rea...

Re: XJR Jag

But you reckon that's intrusion / dismantling. Of course there is no reason an installer couldn't or shouldn't take his own work to bits before delivery, and then do or redo leak checks etc. The term is used to highlight that fillstop checking at installation is not intrusive so there is little exc...

Re: Flashlube System Pipe Connection

To give a bit of perspective, I've never seen any injector problem attributable to this kind of lube system. We've all seen goopy injectors or deteriorating rubbers where no lube system is involved at all. The simpler vacuum type systems give maximum dose at minimum demand, and vice versa. The more ...

Re: XJR Jag

Tubbs, my old mate, my bestest friend - no-one is suggesting brimming tanks first go. You add a splash, do the work, then top it off later. And if you let it out without checking fillstop and level gauge, then I think you are wrong too. I'm not entirely sure what you mean about the pin shooting out,...

Re: XJR Jag

You do not properly understand the word "intrusive". Do compare what I wrote both here and there, it says "this is what I do" - fill to check. This comes before the fullpage explanations of why you don't, then why you do sometimes. There's enough info amongst it for any other readers left to conside...

Re: bad starting on gas

Leaky injectors do happen. There's no reason you can't find more than one issue on an elderly system. With pressure monitor tool (gauge or software), you can check for leakage after gas shutoff. Gas leaks may not be the only reason for poor starting. The petrol host system has an element of self-tun...

Re: XJR Jag

It's not about anything going wrong in time, simply verifying your own work at point of sale. This ain't an onerous, complicated, intrusive check. It takes longer to justify not doing it, than to actually do it. There's a choice of attitudes clearly visible here - "how much can I do" , or "how littl...

No, he told us himself he usually puts half a tank in, and never fills it.

I am envious of your car by the way - a 'proper' (6-cyl) XJ with all that oomph.

Re: DIY closed loop

In this day and age, a microchip costs much the same as a 555. It's capable of performing additional support functions - RPM safety shutdown, tank level display - and adding finesse like sensor failure detection and overrun fuel cutoff. Even for a one-off hobby project, development using something l...

Re: XJR Jag

The argument is over Simon's attitude. He laughingly says that no other installer makes this simple check, that simply isn't true. Comparing "scores" is a bit tricky, Catch-22 style - Simon has never known a new fillstop fail ... trouble is he doesn't check them. I've had exactly two on new installs...

Re: Cold starting, not a problem, just a discussion.

Even gravity can have an effect, say you park up on a slope with a manifold full of gas/air mix - it can settle out overnight and the heavier-than-air gas can run up one end of the manifold, out the air intake, or whatever - any of which could have a good or bad effect on restart. Could depend on wh...

Assuming it is switching normally, the usual suspects would be clagged distributor, DFCO valve, goosed VG392 reducer (regulator), perished vacuum pipes. Search old posts for help on these topics.

You're always telling us no-one else works to your standards, so accept it here too. Some of us do always fill a new conversion, verifying capacity and fillstop action. That's a lot easier if you have your own pump of course. It's not a margins issue for us, cost appears on the bill as explained to ...
