I've got an original '87 GN (only the wiper motor, power antenna, brakes and exhaust have been replaced) and my mechanic says the fuel pump is about to go (only 28 psi at idle).
I don't race it at the track, but never say "never". I like it being nearly 100% original, but a few improvements is not out of the question.
So, my question is "Should I replace the fuel pump with an original fuel pump (lifetime warranty) or should I upgrade to an aftermarket pump like WALBRO (1 yr warranty). BTW, the mechanic wants about $400 to replace with original spec fuel pump. Is that a fair price being that the pump is in the gas tank?
That is not a bad price, it should include a new fuel filter.
I would go with an aftermarket pump, Armstrong XP or the Walbro. You should also install a hotwire for the pump and a fuel pressure regulator.
Don't worry about ruining the 100% GN. These are expected upgrades.
Hello,
The nice thing about the fuel pump is that you can't see it. Some people are really in to the totally stock look and it can be done. A few years ago (they probably still do) Bowling Green Customs sells a stock looking adjustable fuel pressure regulator. It uses a little allen's head inside the vacuum side to adjust. You may want to dig in the archives as it was really hit or miss if people liked them or not. I do, and you can't tell it's adjustable from the outside. The hot-wire kit for the fuel pump, while a purist would know, could fool about 98% of the population that it's there. As for the fuel pump, suggestions have already been listed here, as the times it would take to change a pump/wire/regulator. I think in my garage it took about 3 hours (not in a rush, taking breaks, making sure things were right, ect.) Either way, good luck.

Roger that.
Thanks for the advice. I'm thinking of buying either the Armstrong XP or the Walbro fuel pump because I think they are better than the original. I might wait on the adjustable fuel pressure regulator though.
Anyway, thanks for the great advice!
