My RS Turbo S1 has been laying in storage for the last 15 years, finally getting around to getting her out again but I've hit a problem.

I've replaced the fuel pump as the last one was stuck.. but now I've put 20litres of fuel into the tank and with the pipe to the pump off I'm still getting no fuel out.

Have s1 got a swirl pit or something on outlet that could be blocked?

 

Possible that a breather has blocked, you need to check all the fittings and find a way to blow through the fuel lines or replace them all.

Drop the tank out and check for corrosion.

 

OK will do.

But if there's fuel in the tank should it not surley run out the bottom outlet pipe?

 

I'd drop the tank. 20litres is alot of weight behind whatever it blocking the outlet.
Probably a chunk of rust or similar but either way id have the tank off to remove the blockage and do a full clean out of the tank as otherwise 15yrs of shite will get forced through the entire system..

 

If I could get it unblocked I would let the fuel run out of her but there isn't even a drop coming out.

What's inside that outlet? I can only get in about 3 inches then hits a wall. Was thinking maybe try blow air in to try unblock it but I'm unsure of what's even on the other side.

 

There will be a swirl pot.
Even if you get it flowing, gravity draining wont clean the tank out.

 

OK I've now rigged up an external jar of fuel to try get her started. I've now got fuel coming to the metering unit but not going out to the injectors?

 

Bleed the injectors
But then again they could be clogged with crap too.....

 

No fuel even going up the lines out of metering head.

 

The metering units are very sensitive to any dirt/debris. The fuel can also turn into some kind of gloopy mess if its gone stale and sat in there- more so for 15yrs. Unfortunately they arent something you can split apart and clean easily (without completely ruining calibration).
Might be worth sending to a specialist to strip down and rebuild. Or swap out for a known working one if you have access to spares.

 

Just bit of an update.

Been working at it again today, when I crack open the steel pipe going to the pressure regulator I then get fuel going up the injector lines out of metering unit.

Does this indicate a bad pressure regulator? Nothing coming out return end either.

 

Anyone able to shed any light here? When turning the car over trying to start there should be fuel returning to the tank yes or no?
