Questions Post AFPR & 255 Walboro Install

[johnny boy 93]

Hey guys,

I Installed my new afpr, and my new 255 pump in the last couple days and got everything running last night. Now I id everything properly I believe, but I just had a couple questions.

1. I used weather proof shrink tubing on the fuel pump where I had to solder. Will the gasoline eat away the gunk that comes out of the weather proof shrink tubing. And in turn, will this create a short and cause a problem. I really don't want to be driving my car down the highway and then have it randomly combust or set on fire because the shrink tubing I used did not seal properly.

2. When I rev my car now if I go up to about 3000 rpm then let it drop and quickly rev right after oh say about 2000 my car has a little hick up. Is this just the new fuel pump or what?

Questions, comments, and answers appreciated.
John

Stupid question but, did you set base fuel pressure???

not sure what weather proof shrink tubing is... but gasoline can disolve certain rubbers and plastics, just not most. Not sure about clear heat shrink tubing, but the black and color tubing should be fine

Gasoline does not conduct electricity (like water does), so as long as there is no possibility for direct positive to negative contact, you'll be fine

HI John,

If you bought Dual Wall heat shrink similar to the one at Adhesive Heat Shrink : BuyHeatShrink.com : Adhesive Polyolefin : Dual Wall heat shrink you will be fine. Gasoline will not dissolve or permeate through the inner adhesive layer. It is a high temperature Nylon hot-melt adhesive, resistant to gasoline and common automotive fluids.

Hey guys,
Yeah should have been more specific. I set base fuel pressure to the proper amount without vaccum. It just has this weird hickup. for some reason. Any ideas?

 

[rEclipserGST]

what kind of afpr did you get? how much did it cost? i alrdy have a 255 walbro and i still need an afpr

 

[johnny boy 93]

I got an aeromotive. It looks great and works great, but for some reason this stupid hicup is bugging me.

might need to do a re-Wire on the Pump if u havent cause i get the same thing and i think i might try that on mine and see if it fixes the prob.

Yeah, I was afraid you would say that . Well you plan to do it anytime soon?
