budsaipan Posted September 15, 2011 Report Share Posted September 15, 2011 What is the proper fuel line size,do I need for twin mikuni 44's? It's a lz22. I have a fuel cell with carter fuel pump. What's the rize size all the way through from the fuel cell? It won't have a return either. Quote Link to comment
banzai510(hainz) Posted September 16, 2011 Report Share Posted September 16, 2011 the stock size line should be fine and run a fuel regulator. Really what ever hose size fits on there. pretty simple. The stock fuel pump could handle this Quote Link to comment
budsaipan Posted September 16, 2011 Author Report Share Posted September 16, 2011 I have a carter fuel pump since I wanted to go electric. Thanks! Quote Link to comment
banzai510(hainz) Posted September 16, 2011 Report Share Posted September 16, 2011 ON 510s there is a blue air condition wire under the fuse box. I dont know on 620s if there is one but can assume there is . Previous owner used this to power the eleltric fuel pump on my yellow car Quote Link to comment
budsaipan Posted September 16, 2011 Author Report Share Posted September 16, 2011 My truck came with AC. But it came with a mechanical fuel pump and I know it came that way because there's no sign of bolt holes where the electric fuel pump should have been for the ac models. Weird.. Good thing, I picked up a relay kit for the fuel pump. Do we need to wire in a fuel pressure switch to it? Quote Link to comment
