i want to by pass my origanal fuel filter with hose and a unaversal filter.from the frame rail to the tb. what type of fuel line should i use since it's pressureized.has anybody done this ? what brand of filter did you use ?

 

I would have to ask why....? Wouldn't it be easier to remove the old filter and install a new one?

You will want to use 3/8" steel fuel line (from your local parts store) and a few fittings. Flared fittings and a flare tool are the best route, but if you wanted to just use compression fittings you can get away with that too. Although pressurized, it's considered relatively low pressure and won't break open a compression fittings.

 

you only have about 15ish psi of pressure in your 88'. So blowing a hose wouldnt happen unless its loose or not connected to some kind of flared end.

 

to workshop forever.it seems i have take the whole line out from the frame rail to the tb to install a new filter. those two hose clamps under the filter i can't even see let alone get a screw driver on them. this makes me want to just go with the hose and universal filter...to workshop and chris regarding the flaired ends. the fitting on the frame rail is a hose with two hose clamps holding it. then to the bottom of the fuel filter the hose slips on with two hose clamps . why would i need flaired ends ?

 

where have you gone .no answer to question

 

Been busy,sorry.

Forgot about the rubber sections of the fuel rail.

Cut the steel line on the other end,reflare it so the hose will have something to grip onto.
Run from that,into another flared steel line. use a clamp, you should be good to go.

 

that sounds like the easiest fix and the simplest .how do i get the fuel line off the bottom of the fuel filter that has two hose clamps on ti.i can't seem to get to them do i have to take off the power steering pump ?

 

Do you have the 2.8? I know on the 4.3 the fuel filter is on the frame in front of the tank. Im honestly not sure how exactly the filter is rigged on the 2.8. I "think" its up in the engine bay,which from what you said i guess it is. If it has rubber hoses running to the filter,just follow the hoses back until you hit a metal line and cut the hose there and get it off the steel line,then just run fresh hose up to where you can reinstall it onto a steel line. Im not sure how its ran on a 2.8,so maybe im totally off.

 

First off the pressure isn't dropped to 15 psi (if even that high) until it gets to the reg in the throttle body. Its something like 60psi in the feed line.

On a 2.8 4x4 the filter is behind the powersteering pump in the engine bay. On a 2.8 2wd its on the frame rail just about under the drivers seat.


I've never had any of the problems you describing with my engine. It takes all of 15 minutes to swap the filter on my 87. Ya might as well just pull the entire feed line off from the frame and run all rubber hose up to the tb. You can then use whatever cheap ****** filter you want. Just make sure the filter is designed to handle the pressure of a fuel injection pump. Carb filters won't work.

 

I apologize, my answer was based on the 4.3, which has the filter on the frame rail under the rear door. I did not realize it was different with the other motors.
