Hose from fuel pump to swirl pot ?
Discussion
Hi All
As car up on ramps and axle stands doing a lot of checking cleaning underneath, and noticed the hose stated is starting to split/crack just after where fitted with the jubilee clips at both ends, there is a fair bit of hose so was thinking of just cutting back as required and refit with new clips. Will I get petrol coming from here when I disconnect, would expect some but will there be a lot as tank is half full at moment.
Thanks

There's an almost random selection of hose sizes on the rear tank set up, and I suspect it changed over the years. I wouldn't try and shorten an existing piece of hose as it hardens with age, new hose is readily available so why do that?
On my cars (both '86) the pipes into the 'swirl pot' are 5/8" and the outlet is 1/2".
Most of the rest of the pipe is 8mm (from pump to engine) but the return line to the nearside tank is 10mm at the tank (so needs an 8-10 adapter); and the vent off the 'swirl pot' to the nearside tank is 6mm (1/4"?).
The large diameter pipes are available from Merlin Motorsport (as fuel/oil hoses) and the big filler pipes, if you need them, can be bought from cbsonline. Make sure it's all unleaded compatible, diesel fuel hose or unlined silicon pipe will NOT do!
I wouldn't advise just changing one of them, do the whole lot while you're in there. Removing the nearside tank makes the job a doddle too; empty the tanks first by wedging the AFM flap open and running the fuel pump using the ignition switch to drain the fuel into cans. There's a one way pressure sensitive valve on the pump outlet so you can disconnect that without loosing gallons of fuel (only the fuel in the line to the engine will drain out).
And make sure no-one wanders up to you with a lit fag while you're at it...

Thanks for info was going to ask where you are located replying at that time but you are in Florida it seems, was there last year with the family, we were supposed to be doing Daytona but unfortunately we didn't make it. In fact they are going back in a couple of weeks.
Thanks for your input
