Fuel System for 403 + APS TT

[torinoman]

Recommendations? I'm not going for broke right now. The motor started as a nitro pig and has found a life as a DD. It has 11:1 comp and a giant cam so until I can afford to change the pistons and cam I'm going nice and safe. What pump setup can I get away with as its a DD? I know that 60lb injectors are called for but are the new 80s available yet? Should I go 80 now in anticipation of turning up the boost in the future?
I know these are very generic questions but whatever. Its built motor and turbo related so everyone loves to debate this stuff

For a similar setup I went with twin walbro inline pumps, havn't had an issue. Drilled the fuel tank for #6 fittings.

I'm sure you could leave the factory intank pump (or add a walbro), drill the tank for an additional Walbro to go inline and Y to the factory line. Would have to disable the intank regulator. Add a regulator at the fuel rail and return line.

80 lbs hr injectors are available

I think Fraser has the right answer but just wanted to throw another option.

Could do a walbro 255 and a boost a pump and save some money.

Assuming your running the 7lb waste gate springs on the APS TT? You need to get your compression ratio down.... can you put 317 heads on it and get the CR down?

APS has their fuel system that's all ready to go! Using one on mine to feed the supercharged 427

anything but the aps fuel crap, their engineering is crap! well, unless u wanna spend money re-engineering their crap. lonnies seems to make a nice system ready to go. i suggest a dedicated line to each fuel rail.

How much hp are you planning on making?

Ok, so what's wrong with it?

[2QWK4RU 06 GOAT]

Ok, so what's wrong with it? well it started with them sending crap fuel hose causing explosive vapors in the cabin, then their 16 gauge positive and ground wire running from the battery to the trunk... 2 high output pumps require just a bit more. hmm let's see, what else... the fuel line in their kit was the wrong length, their fuel rails had a few injectors puking fuel on the intake and now 4 the big finale! their fuel bucket was not engineered. All the fuel escapes

oh, btw, nice avitar.

Damn, sorry to hear that!! I've always been impressed with Peter's products! Did they rectify the problems for you? Hey thanks! That's the blower on my motor. How ya like your AP brakes?

[torinoman]

I'm hoping for 650-700 right now. Will a Walbro 255 and a BAP support that till I turn up the boost? Whats the power limits for 60s?

How ya like your AP brakes? aps didn't do shit, well except have me remove my tank twice to check bs. my brakes stop like a mofo! there is a harmonic issue with the fronts though. they are an oem fit, which is nice.

So did you start over or fix the problems? Nice, can't wait to try my Harrop's. How big are they? 15's/14's here.

How big are they? 15's/14's here. all lines are new except the tank drop in which needs to be modded next.... so for the most part yeah. i think they are just under 15 and 14 and a quarter in the rear. they bolt straight to the spindle and axle, no additional brackets. pm me with pics dnt wanna crap op thread.

60's should do, one pump will be at the ragged edge of safety.

safer alternative? whats the limit on the 60s?
