AJRTDDI Posted November 4, 2014 Share Posted November 4, 2014 Hey guys. Iv decided to carry on with my project. Iv finished up a lot of welding. battery tray.. fuse tray.. both sills both rear wheels.. ect lol I'm dropping in the st170 engine and escort Rs gearbox Because my mk4 was rocking a 1.4 carb. What can I do for fueling ? Because st170 is ofcourse injected and non return system it uses the control module to adjust fueling via voltage to the pump Can I install a inline pump or do I need a new tank ?

AJRTDDI Posted November 4, 2014 Author Share Posted November 4, 2014 As anyone ever sent a 5v signal back to the ecu on the fuel rail sensor too trick the ecu too allow the ignition too work. Then just use something like a sierra pump and filter with a return style rail with fuel regulator? Quote Link to comment Share on other sites More sharing options...
AJRTDDI Posted November 4, 2014 Author Share Posted November 4, 2014 Had them specs from a ford forum St170/SVT fuel specs Specs are as follows: Max Power Consumption @ 30Lph/270kPa = 50W Max Current Draw = 10.1A Nominal (NEW) = 8.49A Nominal Performance = 154Lph Min New = 125Lph General Test Condition = 12.0V/350kPA Range: 208-284LPH It's gonna be hard to run a inline pump on a returnless system.

MattDRX Posted November 7, 2014 Share Posted November 7, 2014 Can you not get the whole fuelling system off of a smacked one in a breakers yard? plenty of CAT c's about, bit of a pain to change a fuel tank over, aftermarket fuel pumps are also horrendous money as you've probably found out, I'd go with just taking one from the Focus, at least you'll be happy knowing it'll work without issue.

AJRTDDI Posted November 7, 2014 Author Share Posted November 7, 2014 How would I fit a focus tank in a escort tho.. ? Quote Link to comment Share on other sites More sharing options...
AJRTDDI Posted November 7, 2014 Author Share Posted November 7, 2014 Can I fit a efi tank and swap the pump from standard one to st170. Not all mk4 are I line pumps ? Quote Link to comment Share on other sites More sharing options...
AJRTDDI Posted November 8, 2014 Author Share Posted November 8, 2014 I have a feeling this is a stupid idea. I think missing pcm unit and cluster will stop the engine running ?? Quote Link to comment Share on other sites More sharing options...
