i have an outbord fuelpump and its shorting out and i dont need that much pressure for my 302 so i am i going to get a stock fuel pump for my 302 does it goe on the block or on the firewall? and with my 302 am i going to have to lift it out to put new headers on them. And how much psi do i need in them i have a 73 with i think the 8 in. rear.
I assume you are going with a stock mechanical fuel pump in an older 302. It bolts into the timing chain cover on the drivers side near the oil filter. You probably have a block off plate on it that you will have to remove. Also, there is a cam eccentric inside that has to be in place....some people leave these off if they install and electric pump during a build. I hope you have this or you will have to stick with the electric pump or remove your timing cover to add the eccentric on the end of the cam. Good luck. Jim
Tell us more about the pump shorting out, is it stopping then starting? This is usually nothing but a bad ground or loose connection, if it is a Holley there is a small screen and such that can be cleaned or replaced in the bottom that could be plugged . If you run a fuel pressure regulator and gage, can set it at 4 to 6 psi. Yes, the engine will have to be raised a bit to install most headers, usually the right side will go in from the bottom but the drivers side has to be raised to get by the steering box etc. Air shocks are mainly for towing or carrying heavy loads, the pressure will depend on what height and ride comfort you want without a load, your choice.
air shocks I had air shocks in my mav for 2 yrs, mostly just to lift the rear, what I would do is air them up till the back end was all the way up then start letting air out till the car just starts to drop and leave it there, you wont get quite as hard ride and alot less chance of breaking the shock mounts,I would never run them fully maxed out!! I've had them on quite a few cars with out problems as long as your careful, NO HIGH SPEED U-TURNS, I learned the hard way back in my HS days I spun my old fairlane around at about 35 mph on dry pavement and tore the shocks right out of the shock mounts, bent both shocks, messed up fenderwells and wrecked a pretty new set of N50-15 M/T indy profiles. I've learned alot since then.
Most air shocks have a max psi of 125 lbs. I use them for load leveling for trailering (not on the Mavs, obviously) and 90-100 lbs holds the rear up with a trailer loaded and passengers in the SUV on the Cherokee. You shouldn't need anywhere that much just to bring up the rear on your Mav.
I just put a set of Air Shocks under my Mav. The ONLY reason I did this was to keep the differential bolts from beatin the crap out of my exhaust system. I only raised it about an inch which was sufficient to do this...took about 40 psi to do it. I may be the exception but I found the ride to be very good compared to the stock shocks that were on there. I wouldn't recommend raising them any higher or putting any load on them without welding in reinforcement plates at the top mounts. Of couse this is just my opinion and experience doing it.
my fuel pump is a morso 8psi... it keeps burning trew two fuses a day... its not a bad ground we already regrounded it two days ago.. its not a fault power line we checked that two.. its not dirty i clean it out every month i might stick with a electric with a lower psi..
Bad thing was they were on here when i got the mav.. but i was thinking of moving them to the front this is going to be street show car that i want and i want to put a cobra 351 in here full alum block(power-weight)just put the shoucks up there and keep them normal when i am driving but lower them when i am showing it off....dont wory i am not going to do this for a long time.
Why not air shocks? Honestly, Why not use air shocks? we have used them the last yr. We only put them on to raise the rear a lil. But I am curious as to why not use them. What are the pros and cons? Other than if you lift it too high. Bill:confused: Hoping I can finaly get to the interior!!! (but seriously doubting it)
Mainly because it tears the shock mounts apart. They were never designed to hold the kind of load air shocks put on them. I have spent a couple of hours welding mine back together because the previous owner put them on. There are MANY others on here that have had the same thing happen. Older Mustangs also have this problem.
Thank you. Well keeps looking as tho the interior is juss getting farther and farther away from me lol. Ever spend time & $$ on something THINKINg you are improving it, only to find out you screwed yourself? Over half of what Ive done/had done seems to be that way. oh well 1 Day!!!! LOL 1 DAY!!! I will get this car right. But looks as tho to do it I will be throwing away/hiding a bunch of reciepts. Bill
How well i find that mine are cracking and worn out?i dont see any damage now but i think my mav looks good with the back end lowerd...
just got back from autozone and found out its not my fuel pump its still good just some faulty ford harnes wiring that just gave up...well i orderd a new fuel pump with 3-4 psi.. i am going to clean up this one and sell it if any one wants a fuel pump i might trow in a fixer kit for it...
