Colinb17's Little Red Rocket Build: 1988 Fiero

Wow. That means that under the same driving conditions, you should pick up at least 1-2 MPG's now.

I know you have heard me say it before, but I think you should run this through, if you haven't already. After a fuel filter change, unless yours in already new?

PO had a receipt that showed an oil change a few weeks before I bought it. only put a few hundred miles on it since then, but purely because I don't know what kind of oil/filter was used, i'll probably change it at 1000 miles.

PO put a reusable filter in it. looks like an AFE or Volant. so that's been cleaned.

I installed a new serpentine belt

I tested the oil pressure with a gauge, and then installed a new sender (oil pressure confirmed good)

fuel mixture is calculated based on coolant temp, so to make sure I'm getting a proper mix, I have a new coolant temp sender on my work bench, waiting to go in.

new plugs and wires is the next thing on my list that could have a noticeable affect

I ran the redline cleaner through the last tank of gas, so I'm banking on that taking care of the single fuel injector.

had some rotted/rotting vacuum hoses, so I replaced anything rubber and round under the hood

edit: I do need to change out the fuel filter. thank you for the reminder.

 

And the fuel filter?

 

I watch a lot of Roadkill. That always seems to be one of the first things that they need to do, but always forget until later. Lol.

 

edit made for filter.

the one installed is not the original one from the 80s, but the PO did not take a lot of time to clean the undercarriage, if ever at all, so it's ahrd to tell just how old it is. you have any favorite brands? I just need to figure out the fitting size

 

research complete! M16x1.5 inlet and outlet. found a replacement set of O-rings. just need a filter now.

 

Depends on who makes filters for it. If it is vehicle specific, or just a universal style?

 

K&N, AC Delco, Wix, Mann.

No Duralast, Fram, or anything cheaper.

Those at the top came up pretty quickly in a brief search.

 

universal it would appear, with female M16x1.5 fittings on either end




I will have to check, but I believe it is mounted to the firewall, with a hard line on the inlet and a soft on the outlet.

if the above is true, that would give me some flexibility as far as filter diameter and length.

it looks like the higher end filters come with AN6 fittings (male) standard. if I have the room, I could always get some M16x1.5 (female) to AN6 (female) adaptors.

 

Definitely Mahle.

 

I don't know if that's the one I have installed, I just know I can get that one. Those are good?

Is there any drawback to going with one like this? If I go too small on the microns, do I risk overworking the fuel pump? Or is it just not worth the money on a car like this?

 

If you were using very expensive injectors which required very fine filtration, then I would get the best filter you can. Yours is a much broader range, and I feel that the Mahle will do you perfectly.

 

Fantastic, thank you Mark

 

And I only have one injector..... No plural here

 

Tacoma vs fiero for scale.
Hood of the Tacoma is higher than the roof of the fiero.

Truck is at 1" of lift with 35s.

 

Stance.

 

you forgot the tic-tac-toe grid before it.......rookie mistake.

 

new spark plugs, wires, fuel filter, filter connection 0-rings, and thermostat have been ordered.

no idea what condition the thermostat is actually in (could be fine), but the mom and pop fiero parts store I order my stuff from is having one of their rare sales, so why not. can never have enough parts.

 

All parts which will only extend the life further.
