Just installed my 255lph High pressure fuel pump

[Stangfreak95]

Well one less thing left to do. Installation was a breeze except the damn fuel lines were ceased bad. Had a friend to help me take them off. I was doing this in my driveway as usual

Didnt try it yet but I'm sure it works. Tomorrow I'm going for the HPM driveshaft loop

Cool! I installed the same pump in my car a couple weeks ago. If I can do it and get the car running, you shure as hell can!

Yes they are in-tank fuel pumps. It really is not that hard. Just those stupid lines were hard to disconnect. Easily done in the driveway.

I can now say that I'm officially "looped" Installation was more complicated than I thought. I knew that I had to remove the carpets, seats but I had problems under the car.. My BBK O/R H-Pipe had always been a little crooked and thats what gave me trouble. Anyway...Its done.

One thing less to do: 31spline Axles and carrier

you know a bit about fuel pumps ?

cuz I think mine is ****ed ! I have to crank the ignition like 5-6 times to let the fuel go in the lines to start the car without hesitation... you know what I mean... If i start on first crank it just cant start, i have to pump the gaz and then it starts.. i guess my fuel pump is ****ed ?

Actually I dont really know about fuel pumps...I know that I needed one no matter what for the nitrous but I'm pretty sure mine was defective with all the idling/fuel problems I had. I started the car yesterday (didnt drive it) and it ran very good. No idle jumping like it use to do. No matter what this is a good mod for me.

If I still have those problems, then it's the injector tables that I have to change in My EEC Tuner but I have no clue what to change them for We'll see..

Sounds like the regulator is allowing the fuel to drain back to the tank. The reg should retain pressure for a little while after you shut if off. I don't mean overnight or anything like that. If you can put a guage on the fuel line run the car and then shut it off and observe the gauge. Pressure should fall slowly. If it goes away rapidly its time for a new regulator. If car stutters or falls flat on acceleration I would be more inclined to blame the pump. And I am wondering how the orignal poster had seized PLASTIC fuel lines?

When you put a 255 in, do you have to change all the fuel lines system? Or only the pump?

 

[pricha]

Just the pump..

I'm sure you know what I meant. The connections themselves were just not letting go with the plastic fuel disconnecting clips that I was using. Its a very common problem. Even if the car is rustless and has no winter, those lines were jammed on there believe me.
