hey guys i just got my allen kit in the mail for my 99 4.6l F150 and i was going through the parts and its missing the fuel pump and supplemental fuel pressure regulator.. ok i got the kit from www.Jdmotorsports.org and they said it was a complete kit.. now that i got it they are saying that the kit dosent come with those parts!! so i called allen superchargers and i know i got lucky when they picked up but the guy said i needed those parts unless i were to get bigger injectors, chip it and get a tune.. What should i do? on one hand im missing parts from what was said a complete kit and on the other hand i got it really cheap off there hands brand new minus some key parts..

If anyone has installed one of these kits please help me out with any info..

melmans expy has one of those on it

 

When I bought my kit it had a fuel pump and FMU(I think that's the supplemental fuel pressure regulator your referring to.
I got it right from AED.
You will need one or the other set up.
I ended up putting in a bigger fuel pump(255 Walbro) 42 # injectors and 90mm Lightning mass air sensor. And a custom tune.
That is the way I would recommend doing it. It may cost a little more but you'll be one step ahead of the game.

thats what im thinking about doing now that i have read up on how the FMU works. it dosent seem to be very reliable and if it does fail my engine could be ****ed..

 

Hey guys how is your gas mileage now that you changed your injectors and fuel pumps ? i dont want to go to big because its my daily driver you know.. what injectors and pump would you recomend for me if i was trying to keep it somewhat gas friendly???

 

Melman got his from Troyer Performance you might want to give them a call for your tuning

 

If your worried about gas you might as well turn around and sell that thing right now
I don't think the injector size will effect the mileage as much as your heavy foot will. When you feel the power of a roots blower,,it's sooo much fun to drive it's hard to take it easy and save gas!!!
If you can drive it normally ,,your gas mileage will improve!
Most go with the 42#s and 90mm mass air. There made for each-other and makes tuning much essayer. + by going with the 42s it will leave you some room for upgrades!

I'm running 60 ponders with my setup and 2/255 fuel pumps.

no its not that its just its my daily driver you know.. im pretty good at keeping my foot off the gas but ill have to see how fun it really is first!! I wanted the S/C for more power not really to go fast.. i have 37's that slow my truck down allot and was looking to get it back but now that im missing those key fuel parts in the kit it looks like ill have to go this route !! not to bad just take me a little longer than planned
