Back to some Tech talk guys!
I bought a 71 roller that came orginally with a 1.7 D jet. I guess the PO found another motor a 1.8 L jet and this is what it came with. My question is this: Will I have to change anything with the fuel pump, on the late models the pump is up front, with the early models its in the back. Does anyone know if this is gonna be a plug & play or am I gonna need to do some rewiring. Thanks for any input guys! (IMG:http://www.914world.com/bbs2/html/emoticons/flag.gif) KevinP |

as long as you all of the L-jet wiring harness it should be an easy swap...I converted a stock 2.0 to L-Jet and had no problems....no big deal on the fuel pump location, you can keep it where it is.
you won't need the relay on the board for the fuel pump, it will be powered by the dual relay on the L-Jet wiring harness |

if you have the complete l jet and harness, its plug and play, but you dont need the the relay on the reg board for the fuel pump. the d jet fuel pump will work fine, but you can relocate it up front to prevent some of the hot start issues ( vapor lock )
damn you mueller beat me by one second This post has been edited by scott thacher: Jan 21 2005, 03:19 PM |

WARNING OPINION: Why bother ? if you gonna swap a moter from 1.7 go 2.0 ....Easy. The diff youd realize from 1.7 to 1.8 w ould not be worth it. (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

Unless of course the 1.7 doesn't work anymore and the 1.8 does? (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
