1972 GMC K5 then and now

This is probably one of those threads:
http://www.chevelles.com/forums/89-efi/893641-return-style-fuel-filter-ls-fitech-install.html

He followed up and it worked for him.

So I read through that thread and the related one and see that a few people had luck with running the corvette filter return. They mostly ran it for convenience and space saving. One thing that was mentioned was the electronics being in the TB and that the fuel return might in fact help keep the unit a little cooler. That sounds appealing to me Since my engine has always seemed to run a little hot.

Could always throw one of their command centers in there. Eliminate the return line. Seems pretty trick http://fitechefi.com/products/40003/

Heard nothing but bad about the command center

 

[Lieferson]

I've heard and read more good than bad. can always send it back if it doesn't work the way it should..

 

[72gmck5]

The command centers have a bad rep and would add a lot more complexity and cost. The corvette filter works allowing the excess pressure to bleed back to the tank but I'm seeing now that it's also somewhat redundant having 2 FPRs. I'm thinking I'll just return that and the adapters I bought for it and get a regular filter, some new hardliners, and run a normal return.

Slow going but making some progress. I got the tank inlet over to the correct side and had to make some drop brackets to space the tank down enough to clear the bed floor, still sits .5" higher than the stock tank. A body lift would make this so easy.

nice work man.

 

[Bent77]

Plan on protection for that?

Plan on protection for that?

I mean its a metal tank so it should be fine, right?

 

[Bent77]

I've seen you drive. So...

I've seen you drive. So...

I only drove half that trail...

I do plan on making a skid for it.

Just for reference I used a 1.125 square tubing as the front crossmember. Sleeves the holes for the strap threads to go through.

Transmission #2 installed and seems to be running gooder. The trans work was warrantied out along with a new torque converter which we switched out for an 1800 stall instead of the 2500. The cause of the failure was the front pump bushing came loose and got chewed up taking the front seal with it.
took some time this last weekend to button it all up and it back on the road. Since yesterday was so nice out I decided to put it through the paces taking it up Butterfield Canyon to the Kennecott Mine overlook.
And now a little picture whoring.

My Jimmy wants to be just like your Jimmy when it grows up. Nice rig.

 

[72gmck5]

I had to feed mine copious amounts of dead presidents to make it grow to were we are today.

Up and running! The instant gratification when it fired up on the first try!

The linkage is the same as a Holley and their bracket pn20-121 just needed a little alteration to fit and operate the tv cable.

 

[skunked]

f*ck yeah!

 

[72gmck5]

Been driving the Jimmy daily and it's been awesome. The engine runs smooth, has more consistent power. Fires up on the first try, no pumping the gas pedal, and no fumes from flooding.
There's still some fine tuning needed but it's night and day difference on drivability.

Today I dropped it off at the local firestone to get some new rubber installed. 38/13.50/r17

Should have it back in an hour or so.

Back and looking a lot better than the 35's that came on the H2 wheels.
