Have had my Pinto running on Twin 45 throttle bodies for 3 years now without a glitch. On the way home from SFS this year the car wanted to stall. I believe the fuel is vaporising as it seems to happen on hot days. For ease of installation when I setup the car, I mounted the surge tank next to the radiator in the engine bay. It is fed by the standard carby mechanical fuel pump. The swirl pot then feeds the high pressure bosch pump (mounted under the air filters) and then to the fuel rail. I think my problem is that the hot fuel never leaves the engine bay thus creating the problem. The car has done approx 10,000k's with this setup and has done it well but I am starting to lose faith in it's reliability.
 
I am looking to design a new fuel system and change the injection to sequential at the same time. I would like to run an in-tank fuel pump and possibly even a non-return system. Not sure if anyone has done anything like this so I am after information or ideas. I will be modifying one of the drop tanks I have to take some kind of swirl pot but I am not sure how it would seal or what fuel lines / connectors I would need. Would also like to fit up some kind of carbon cannister or purge line. Any ideas appreciated as I need to do something before summer comes back again.

How about bolting a Skyline intank pump system into the drop tank and trying that? You'd need a new fuel line from the tank to the engine though.

Just a thought - the fuel could be getting pressurised by the heat in the engine bay, resulting in incorrect pressure at the injectors (or inconsistant pressure). Do you currently have a fuel pressure regulator fitted? with return line to tank fitted?
My basic understanding of a fuel injection set-up is you will need a return line to the tank.
I could be wrong - just a thought.

Brett, I have a fuel pressure regulator at the end of the fuel rail, just before the fuel returns to the surge tank, then excess back to the tank via a return line. I think the main problem is that only a small amount of fuel is leaving the hot engine bay.
 
I am going to take a trip to the wreckers on the weekend to look at various fuel tank setups (mainly the pump coverplates) and see what I can get to graft into the Escort tank.

This is kind of what I was thinking, except I am not keen on cutting the boot floor for the pump to stick through.

Excellent. I have a spare drop tank here if you need a spare to help dummy things up.

i just run a side tank (should cut down on surging itself) and a vl fuel pump

dont like your surge tank in the engine bay. but as you said it worked fine for several years. check your high pressure pump isnt getting hot. we had bosch high flow which was still pressurising but found it was heating up and inturn heating the fuel. Unused fuel is returned to the surge and heated more.

Thanks RallyRS, I agree that the surge tank in the engine bay was not an ideal spot. When it happened the first time you could hear the high pressure pump whining like it was aerated. 
I have been doing some research today by visiting the local wreckers to see what setups there are around that may be able to adapt easily to the Escort drop tank. I found this site also which I quite like. http://www.tanksinc.com/index.cfm/page/ptype=article/article_ID=6/art6.htm
Thanks for your ideas and experiences, I hope to get this sorted soon.
