NEED HELP: 1974 1.8L Will Only Start with Brake Clean, Runs with AFM disconnected only Options

[Nor.Cal.914]

Hello everyone,

I have a 1974 1.8L that needs a new fuel pump and the customer purchased this pump from Pelican:

https://www.pelicanparts.com/More_Info/0439...59&DID=4630

I have already figured out the line routing in terms of inlet and outlet, but I do have a few questions about some other aspects. Being that the stock pump is a 3-port pump, first question is, what was the reasoning behind the 3 ports instead of just an inlet and outlet? My first thought was maybe an internal FPR, but I see there is a one in the engine compartment so that doesn't seem to be the case, but please correct me if I'm wrong! Second question involves mounting the pump. I have a 1975 so I'm not as familiar with how the 1974's were setup. This car has the coil style ring bracket around the pump which I'm now trying to figure out if I can utilize to mount the new pump. Main issue of course is the fact that all 3 lines came out on one side of the factory pump, whereas this pump has inlet/outlet on either side.

So my question is, what have you guys done to mount your pumps either in the same location or where did you place it instead of the factory location? Thank you in advance for the help! (IMG:style_emoticons/default/beerchug.gif)

i just noticed another thing.
the fuse board or whatever you want to call that item on the left hand side of engine bay is chock full of the circular relays.
the old L jet does not actually use all of those.
they are mostly absent in your L jet application.

suffering brain fade at present, i could pull the cover off mine (which appears to be missing in the car you are struggling with hence its all visible) to see exactly what is required and not required.

but again its saying to me someone has been playing around in the engine bay with a slight degree of confusion. which is entirely understandable. D jet info would confuse the average folk amongst us - which i include myself as.

i really had to work at it about 5 years back to unravel what an L jet was v a D jet. (IMG:style_emoticons/default/biggrin.gif)
but i am glad i did. my head is now full of useless technological archeology that no one under the age of 45 or 50 is the least bit interested in. (IMG:style_emoticons/default/biggrin.gif)
